Read First: Safety Information
Understand and follow operating instructions carefully. Use the meter,
test leads and all accessories only as specified in this manual; otherwise,
the protection provided by the meter can be impaired.
WARNING
To avoid possible electric shock, personal injury or death,
follow these guidelines:
Do not use if meter appears damaged. Visually inspect the meter to
ensure case and jaws are not cracked.
Inspect and replace test leads if insulation is damaged, metal is
exposed, or probes are cracked. Pay particular attention to the
insulation surrounding the connectors.
Always ensure the meter, test leads and all accessories meet or exceed
the measurement category required in the working environment. (i.e.
CAT rating)
Note that the measurement category and voltage rating of
combinations of the meter, the test leads, and the accessories is the
lowest of the individual components.
Do not use meter if it operates abnormally as protection may be
impaired.
Do not use during electrical storms or in wet weather.
Do not use around explosive gas, dust, vapor, amperage or in damp or
wet environments. Do not submerge or expose the meter to water and
do not use if the meter has ever been exposed to water or other fluids.
CAUTION, when pressing the test button, the selected DC voltage is
present at the exposed test leads tips.
Do not apply more than the rated voltage to the meter.
Replace battery as soon as battery indicator appears to avoid
false readings.
Remove the batteries for storage or if the meter will not be used for
longer than one month.
Battery leakage will compromise the safety of the meter and cause
damage to internal components.
Remove the test leads from the meter prior to removing battery cover.
Do not use without the battery and battery cover properly installed.
Do not attempt to repair this unit as it has no user-serviceable parts.
Use the proper terminals, functions and range for your measurements.
Never ground yourself when taking electrical measurements.
3
Connect the black common lead to ground or neutral before applying the
red test lead to potential voltage. Disconnect the red test lead from the
voltage first.
Keep fingers behind the guard rings of the probe tips.
Voltages exceeding 30VAC or 60VDC pose a shock hazard so use caution.
CAUTION
To protect yourself, think “Safety First”:
Comply with local and national safety codes.
Use appropriate personal protective equipment such as face shields,
insulating gloves, insulating boots, and/or insulating mats.
Before each use:
- Perform a continuity test by touching the test leads together to
verify the functionality of the battery and test leads.
- Use the 3 Point Safety Method. (1) Verify meter operation by
measuring a known voltage. (2) Apply meter to circuit under test.
(3) Return to the known live voltage again to ensure proper
operation.
Always work with a partner.

When connecting the test leads to the DUT (Device Under Test) connect
the common (COM) test lead before connecting the live lead; when
removing the test leads, remove the live test before removing the
common test lead.
The figures on the following pages show how to make basic
measurements.
Measuring ACV/DCV : Auto Sense Function
If the measured voltage is above 660 V ac/dc, “>660Vac/dc”
will appear on the display.
Auto sense mode: The meter displays ACV or DCV whichever is higher
(>0.3V).
If the measured voltage is above 660Vac/dc, “660Vac/dc” will appear on
the display.
6
Measuring Earth-Bond Resistance
Measuring ACV/DCV: Auto sense +LPF function
PRESS
The Low Pass Filter (LPF) mode when activated in the AC Voltage Mode
rejects or blocks unwanted voltage at frequencies > than 1k HZ. The Low
Pass filter can greatly improve measurements on complex waveforms
such as adjustable speed drives or variable frequency drives.
7
1. Before starting the test :
(a) The circuit under test must be completely de-energized.
Check the fuse before testing.
Connecting to an energized circuit while the test is active will
blow the fuse.
See Testing the fuse later in this manual.
If the detected voltage is above 2V, “>2V” will appear on the
display.
In this condition, the test is inhibited.
(b) Short the test leads before measurement, and press the blue
button to compensate the probe resistance for <2Ω.

1. Before starting the test:
The circuit under test must be completely de-energized. If the
voltage detected is above 30V, “>30V” will appear on the display.
In this condition, the test is inhibited.
2. Press the blue button to display insulation resistance or Leakage
current during the test or when the test stops.
3. Lock mode: Press the Lock button to enter the Lock Mode. Then
press TEST button to start the test. The test voltage will continue to
be applied until the TEST/LOCK button is pressed again. NOTE: The
red lightning bolt will appear when the test voltage is applied. The
test button must be depressed or the test mode locked on to indicate
that the test voltage is being applied.
4. Release the TEST button before removing the test leads (to enable
the tester to discharge capacitive circuits). If the screen displays
volts, wait until it reaches zero.
5. The meter displays the “>” symbol and the maximum resistance
for the range when measured resistance is higher than the maximum
display range.

Using the Compare Function
Measuring PI/DAR
1. Before starting the insulation test:
Press the COMP button to select the compare value among
100kΩ, 200kΩ, 500kΩ, 1MΩ, 2MΩ, 5MΩ, 10MΩ, 20MΩ,
50MΩ, 100MΩ, 200MΩ and 500MΩ
2. If the measured value is greater than the selected compare value, the
green Pass indicator will illuminate.
PI (Polarization Index) = R10-min/R1-min
DAR (Dielectric Absorption Ratios) = R1-min/R30-sec
R10-min : the insulation resistance measured at the 10 minute mark
after pressing the TEST button.
R1-min : the insulation resistance measured at the 1 minute mark after
pressing the TEST button.
R30-sec : the insulation resistance measured at the 30 second mark after
pressing the TEST button.
10
The measured values of DAR test
DAR = R1-min/R30-sec
When the measured resistance is higher than the maximum range, the
screen will display “Err” symbol for PI/DAR value.
TEST button : Press once to start/interrupt the PI /DAR test.
Blue button : Use to display and check the time left of the PI/DAR test.
The measured values of PI test
PI = R10-min/R1-min
On many installations, the quality of the insulation is so good that both
the initial measured value and the subsequently measured value (when
performing the PI or DAR tests), will be the maximum that the meter can
read. Dividing one into the other will of course read the value of 1, which
in this case may be perfectly good. It is strongly recommended that
in all cases, you contact the manufacturer of the device under
test or the appropriate manual, to ensure that any reading
meets the manufacturers specification for determining if a part
is good or bad.
11
Using the Store Function
Store/Recall button:
The screen will be flashing the MEM symbol and the number of the
stored data twice when the Store/Recall button is pressed.
1. Press once to store the voltage value during voltage test
2. Press once to store the PI/ DAR, insulation or Earth-bond
resistance value when the individual test is completed.
3. The memory is divided into five segments, each segment has
100 maximum data points. The method to store the data is first
in/first out when the memory is full.

Battery and Fuse Replacement
Refer to the following figure to replace fuse and batteries.
Testing the Fuse
CAUTION:
Use only a fuse with the
amperage, interrupt, voltage,
and speed rating specified.
Fuse rating : Fast, 315mA,
1000V, Min Interrupt
Rating 10000A.
Replace the batteries as
soon as the low battery
indicator “ ” appears,
to avoid false readings.
When the battery is too low
for reliable operation, the meter
displays “bAtt.” The meter will
not operate at all until the battery
is replaced.
1.5V x 4 alkaline batteries.
Remove the test leads before
testing the fuse.
If the display is reading FUSE,
the fuse is bad and should be
replaced.
