displayed only if a calibration interval has been set up)
3. L. BUMP – the last bump test date
4. BUMP DUE or BUMP XXXd. – denotes if a bump test is due or how many days until it is due (will
be displayed only if a bump test interval has been set up)
5. TWA – current Time Weighted Average readings.
6. STEL – current Short Term Exposure Limit readings.
7. HIGH – peak sensor readings.
8. CLEAR ALL prompt – press Power/Menu Button once during CLEAR ALL prompt to clear the TWA,
STEL and Peak sensor readings.
Calibration Information - The date of the last calibration, along with the number of days remaining until the next
calibration is due, will be displayed. If calibration is due, the detector must be calibrated (refer to the Calibration
section, page 12).
Bump Test Information - The date of the last bump test, along with the number of days remaining until the bump
test is due, will be displayed. If a bump test is due, the detector must be bump tested (refer to the Bump Testing
section, pages 9-11).
Peak Levels - The detector will display the current TWA and STEL readings, followed by the peak concentrations
recorded for each sensor since the last “CLEAR ALL”.
Clear Peak Levels - Pressing the Power/Menu Button during the “CLEAR ALL” prompt will cause the TWA, STEL and
peak concentrations to be cleared. Note: this does not remove the information from the internal memory logs of the

Option Menu
The Option Menu is accessed by pressing the Power/Menu Button once during the “SHOW OPTION” prompt. The
detector will display in the following order:
1. FW VER – the current rmware version
2. TWA - the set alarm limits for Time Weighted Average
3. STEL - the set alarm limits for Short Term Exposure Limit
4. LOW - the set alarm limits
5. HIGH - the set alarm limits
Firmware Version - It is recommended to use the most current rmware version available. The most current rmware
version can be easily downloaded from the Resources page of the GCT website at www.gascliptech.com. Firmware can
be installed using the GCT IR Link or MGC Simple Clip Dock.
Alarm Set Points - The current alarm limits for TWA, STEL, LOW and HIGH will be displayed in sequence. Set points can
be adjusted using the GCT IR Link or MGC Simple Clip Dock (see Adjustable Options section, page 7).
ADJUSTABLE OPTIONS
The following options can be congured using the GCT IR Link or MGC Simple Clip Dock:
User ID/Message - An optional, user-programmable, text message containing up to 46 alpha-numeric characters can be used
to show company branding, a detector identier or any other pertinent information. The User ID/Message will be displayed right
after the date and time each time the Main Menu is accessed. Default User ID/Message is "GAS CLIP TECHNOLOGIES".
Alarm Limits - This option allows you to set sensor low and high alarm limits. Each sensor contains separate alarm threshold
values that tell the detector when to go into alarm.
Caution: Conrm alarm levels with local laws/regulations before operation.
SAFE Display - If Safe Display is enabled, screen will display “SAFE” as long as there are no gas or detector alerts.
Self-Test Lock - If a sensor fails a self-test, the detector shows “Err” on the display and goes into high alarm. By default, the alarm
can be silenced by pressing the Power/Menu Button. The Self-Test Lock option prevents the alarm from being silenced.
Maintenance Notication - If Maintenance Notication is enabled, the detector will periodically ash the maintenance LED
when a bump test or calibration is due. Otherwise, if the option is disabled, the detector will only show the maintenance text on
the display.
Dock Lock - This option restricts bump tests and calibrations to only being able to be performed with MGC Simple Clip Docks.
Manual tests will not be able to be performed.
Latching Alarms - Alarms are non-latching by default, therefore, once the gas readings fall back within the set limits after an
alarm condition, the detector will cease to alarm and return to normal operation. Latching alarms will hold the detector and its
display in its peak alarm condition until the Power/Menu Button is pressed.
Life Display - If this option is enabled, screen will display "Life Remaining" as long as there are no gas alarms or detector alerts.
O Lock - This option prevents the user from deactivating the detector's sensors with the Power/Menu Button.

ADJUSTABLE OPTIONS continued
TWA Method - The algorithm used to calculate the TWA (Time Weighted Average) can be set to either an average over a moving
window (OSHA) or as a cumulative average (ACGIH).
TWA Interval - The TWA Interval denes the time frame over which the long-term average is calculated. Default is 8 hours.
STEL Interval - The STEL Interval denes the time frame over which the short-term average is calculated. Default is 15 minutes.
Sensor Enable/Disable - Individual sensors can be disabled. A disabled sensor is completely removed from the detector’s display
for sensor readings, alarm limits and calibrations. This option can be enabled/disabled only with the GCT IR Link.
Caution:
A disabled sensor will not measure gas or detect alarm conditions.
Bump Interval - The Bump Interval controls how often the detector noties the user to bump test the sensors. The interval can be
individually adjusted for each sensor.
Calibration Interval - The Calibration Interval controls how often the detector noties the user to calibrate the sensors. The
interval can be individually adjusted for each sensor.
Calibration Gas - When the detector is calibrated, it scales the sensor readings to match the concentrations of the applied gases.
The calibration gas concentrations can be adjusted to match the respective levels contained within the gas bottle.
Default is 25ppm H2S, 100ppm CO, 18% O2 and 50% LEL (2.5% vol CH4). This option can be adjusted only with the GCT IR Link.
%-by-Volume CH4 - Allows the detector to display gas readings as %-by-volume CH4 rather than % LEL. The conversion rate can
be congured by specifying what the methane concentration is for 50% LEL (typically 2.5% in N. America and 2.2% in EU).
Language - The detector is able to display all its text prompts in any of six languages: English, German, French, Spanish, Italian or
Portuguese. Note: “OL”, “ERROR” and sensor icons (H2S, CO, O2 & LEL) remain the same for all languages.
Activity LED Period - This option allows the detector to ash a single LED at a specied interval to indicate that the detector
is on. The interval between ashes can be set anywhere from 5 seconds to 120 seconds.
• If using GCT IR Link Software - under the Advanced Options section, locate the Activity LED Period box and set the
desired interval by either clicking on the UP arrow or typing the desired interval directly into the box. To nalize, click
on the WRITE button at the bottom of the screen. To disable this function, type "0" in the Activity LED Period box and
press ENTER. The box will display "OFF". Click on the WRITE button to nalize.
• If using GCT Manager Software - place a check on the Activity LED box, then go to the LED Period(s) box and set the
desired interval by either clicking on the UP arrow or typing the desired interval directly into the box. To nalize, click
on the WRITE button at the bottom of the screen. To disable this function, type "0" in the LED Period(s) box and press
ENTER. The box will display "OFF". Click on the WRITE button to nalize.
NOTE: Simply setting the interval in the Activity LED Period box or the LED Period(s) box without clicking on the
WRITE button will not enable/disable this function on the detector.

DETECTOR MAINTENANCE
Battery
This detector is designed so that the battery will not need to be charged during the life of the detector. If the battery is too
low, the detector will display "LOW BAT". If this occurs prior to detector's end of life, contact GCT for technical support.
DO NOT substitute any other battery type than specied and supplied by GCT.
Bump Testing
The detector can be congured to keep track of regular bump testing intervals in a Bump Log. The interval can be individually
adjusted for each sensor using the GCT IR Link software. When a programmed bump test comes due, or if the last bump test
has failed, then the detector’s display will continually ash “BUMP DUE” until the detector has been successfully bump tested.
Performing a bump test that will be recorded in the Bump Log can be done either automatically (insert the detector into the
MGC Simple Clip Dock), or manually (apply gas according to the Manual Bump Test Instructions described below).
Manual Bump Test Instructions
Press the Power/Menu Button two separate times in quick succession (double-tap) to access the Main Menu. The
display will then show, in the following order:
When the screen displays “SHOW STATUS”, quickly press and release the Power/Menu Button to display the current
calibration status followed by the current bump test status. The next step depends on the following situations:
• When a bump interval has been programmed into the detector and a bump test is due, the current bump
test status will show: “L. BUMP ___” (the date of the last bump test) followed by “BUMP DUE”. Audible, visual &
vibrating prompting to apply gas will automatically start. The display will alternate between “BUMP DUE” and
“APPLY GAS”. Clip the MGC-S Calibration Cap (provided with the detector) into place over the sensor ports. Apply
gas to the detector at a ow rate of 0.5 LPM and do not disturb while test is being performed. Once all of the
sensors have been tested, the detector will go into alarm. Remove the MGC-S Calibration Cap and the detector
will return to normal operation after a short period of time. The bump due date will be automatically reset. The
bump test will be recorded in the Bump Log.

• When a bump test has failed, the current bump test status will show: “L. BUMP FAILED” (indicating that the last
bump test had failed). Audible, visual & vibrating prompting to apply gas will automatically start. The display will
alternate between “BUMP DUE” and “APPLY GAS”. Clip the MGC-S Calibration Cap (provided with the detector)
into place over the sensor ports. Apply gas to the detector at a ow rate of 0.5 LPM and do not disturb while test
is being performed. Once all of the sensors have been tested, the detector will go into alarm. Remove the MGC-S
Calibration Cap and the detector will return to normal operation after a short period of time. The bump test will
be recorded in the Bump Log.
Under no circumstances should a detector that has failed a bump test be used.
During a manual bump test, the audible, visual & vibrating prompting to apply gas will continue for approximately
two minutes. If gas is not applied within the two minutes, then the bump test will automatically fail. The prompts will
cease, the detector will return to normal operation, but the display will continually ash “BUMP DUE” until the detector
has been successfully bump tested. Please note, to abort a bump test at any time, press the Power/Menu Button once
and the detector will return to normal operation.
Note - Users may simply apply gas to the detector at any time during normal operation to run a
bump test without going through the steps above. Be aware, this will not be recognized by the
detector as a Manual Bump Test therefore it will be recorded into the Event Log as an Event, not into
the Bump Log as a Bump Test.
If a sensor fails the bump test, display will show “ERROR” and designate which sensor (CO, H2S, O2 or LEL) did not
pass (see "ERROR" display screens below). If this occurs, contact GCT for technical support.

the Calibration Log can be done either automatically (insert the detector into the MGC Simple Clip Dock), or manually (apply
gas according to the Manual Calibration Instructions described below).
Manual Calibration Instructions
To enter the Manual Calibration mode, continuously hold down the Power/Menu Button. Release the button when the
“ZERO OK” message appears. The detector will rst automatically zero the sensors at the current baseline reading, then
the “APPLY GAS” prompt will appear. Display will show:
Once the screen displays “APPLY GAS”, clip the MGC-S Calibration Cap (provided with the detector) into place over
the sensor ports. Apply gas to the detector at a ow rate of 0.5 LPM and do not disturb while calibration is being
performed. Sensor readings will be displayed as the gas is detected and as the detector adjusts the calibration
parameters. Once calibration is complete, the detector will display the next calibration date before returning to
normal (alarming) operation. If a sensor fails to calibrate, the detector will display “ERROR” (an error message for the
failed sensor). Check your gas connections and concentration before attempting a second calibration. If a sensor
fails to calibrate after a second attempt, contact GCT for assistance.
Auto Zeroing
To Auto Zero the detector, enter Manual Calibration mode as described above. Once the screen displays "APPLY GAS", briey
press the Power/Menu Button. The screen will then display "CAL ABORT" followed by the number of days remaining before
the next set calibration date. The detector has been successfully auto zeroed and returns to normal operation.
Auto Zero the detector only in a known clean air environment.
DO NOT Auto Zero in temperatures above or below the specied range of 0°C to 40°C.
Retest
To attempt recovery from sensor "Err", continuously hold down the Power/Menu Button during count downs. Release the
button when the "RETEST OK" message appears. The detector will retest sensors and auto zero the detector. Auto Zeroing
precautions apply.
Under no circumstances should a detector displaying "Err" be used.
Storage
Store the detector in a safe, dry place between 32°F and 77°F (0°C and 25°C).
Review the warranty period and the “Activate before..." date that is printed on the product box label.

DETECTOR RECORDS LOGS
During operation, the detector automatically records all usage activity. These records can be downloaded from the detector
using the GCT IR Link or MGC Simple Clip Dock.
The Event, Bump and Calibration Logs are always downloaded. Partial data logs may be downloaded in order to reduce the
transfer time. Partial data logs contain approximately 1 week of data. New data log downloads will only contain the data since
the last download. Full log downloads contain the entire data log, typically at least 2 months’ worth of data.
Event Log
The detector stores the last 50 alarm events. These are organized by rst in, rst out (FIFO) so the 51st event will replace the
rst event and so on. The detector records the specic alarm conditions for each event as follows:
• Date and time at the start of the event
• Duration of the alarm condition
• Each sensor’s peak alarm status and reading
Bump Log
The detector stores the last 50 bump tests. These are organized by rst in, rst out (FIFO) so the 51st bump test will replace
the rst bump test and so on. Bump tests are dierentiated from normal events when the alarm condition occurs inside of an
MGC Simple Clip Dock, or when the detector is manually bump tested according to the Bump Testing section. The detector
records the bump status for each test as follows:
• Date and time of bump test
• If the bump test was performed manually or with the MGC Simple Clip Dock
• Each sensor’s peak alarm status and reading
• The result of each sensor’s bump test
Calibration Log
The detector records the last 50 calibration attempts. These are organized by rst in, rst out (FIFO) so the 51st calibration will
replace the rst calibration and so on. Each calibration attempt will be recorded as follows:
• Date and time of calibration
• If the calibration was performed manually or with the MGC Simple Clip Dock
• Each sensor’s gas concentration calibrated to
• Each sensor’s calibration success status
Data Log
The detector records its current operational status every second. The logging interval cannot be adjusted, but the detector
compresses the data to reduce the storage and transfer times of redundant records. The typical logging capacity is at least 2
months of data. The following items are recorded into the log:
• Date and time
• Sensor readings and status conditions
• All user and sensor options
• Events (i.e. low alarm, high alarm)
