Description

The Greenlee TG-2000 Infrared and Contact Thermometer is a hand-held surface temperature sensing

device. The non-intrusive measuring capability of this unit is safer and quicker than other methods,

and is well suited to checking the surface temperature of circuit breakers, motors, HVAC/R equipment,

engines, etc.

This device measures surface temperature by gathering three forms of infrared energy — emitted,

transmitted, and reﬂected — from an object and translating that energy into a temperature.

This temperature instrument includes the following features:

• Dual laser sighting. The two lasers indicate the approximate diameter of the measurement area.

• User-adjustable high and low temperature alarms.

• Automatic recording of maximum, minimum, difference, and average temperatures while making

measurements.

• Probe jack. Allows the thermometer to measure contact temperature using any K-type thermocouple

with a standard mini connector.

• Lock mode. Allows long-term measurements without holding the trigger. The lasers are turned off in

Lock mode unless the trigger is held down.

Using the Features

Basic Features

• To turn the laser on or off: Press and hold the trigger, and then momentarily press the  button.

• To turn the backlight on or off: Press and hold the trigger, and then momentarily press the  button.

• To change between Celsius and Fahrenheit: If the LCD is blank, press and release the trigger.

Momentarily press the °C/°F button.

• To lock the trigger for continuous measurement: If the LCD is blank, press and release the trigger.

Momentarily press the Lock button. Momentarily press the Lock button again to return to normal

measurement. The unit will automatically exit Lock mode after 60 minutes.

Advanced Features

Press the Mode button to access the advanced features. They appear in this order: Emissivity Display

(E), Emissivity Setting (iEh), Maximum (MAX), Minimum (MIN), Difference (dIF), Average (AVG), High

Alarm Limit (HAL), Low Alarm Limit (LAL), and Probe (PRB).

Setting Alarm Points

After selecting the HAL or LAL mode, use the  or  button to set the alarm point. A tone will sound

and the alarm indicator will ﬂash if the temperature is higher than or lower than the corresponding set

point. “HI” or “LOW” will appear with the alarm indicator.

Temperature Probe

To use a K-type thermocouple temperature probe (purchased separately), connect the probe to the

probe jack on the side of the thermometer. Select PRB mode. The probe temperature will appear in

the lower right corner of the display. The temperature detected by the infrared sensor will continue to

appear in the center of the display. You may still use the Mode button to access the other advanced

features, but the probe temperature is displayed only when PRB mode is selected.

Note: The probe will not trip the high alarm and low alarm.

Measurement Review

After the unit shuts off, press Mode to review the measurement:

• MAX — the highest recorded temperature among all of the readings.

• MIN — the lowest recorded temperature among all of the readings.

• dIF — the difference between the maximum and minimum readings.

• AVG — a weighted rolling average of all of the readings.

Note: Values for MAX, MIN, dIF and AVG are reset each time the trigger is pressed.

Note: The AVG feature acts as a ﬁlter to eliminate ﬂuctuations from the temperature readings. It is not

an arithmetic mean, but rather a rolling weighted average of the readings that smoothes the data and

excludes sudden spikes.

TG-2000

Distance from Target

Thermometers measure the surface temperature of an object by sensing its emitted, reﬂected, and

transmitted energy. The sensor collects this energy from the area being measured (spot size). The spot

size varies as the distance to the target changes. The farther the distance from the area being targeted,

the larger the spot size.

When determining the appropriate distance from the object, the spot size must be somewhat smaller

than the target area. When accuracy is critical, the spot size should be half as large as the target. If the

spot size is larger than the target size, the thermometer will pick up the temperature of the back-

ground, resulting in inaccurate readings.

1 2

Object 1 is the correct distance from the unit. Note the target is slightly larger than the spot size being

measured.

Object 2 is too far away. The thermometer also measures the background because the target is smaller

than the instrument’s spot size. This can result in an inaccurate reading.

Distance to Spot Size

The distance to spot size is a ratio that provides the appropriate distance to the target.

The nominal distance-to-spot-size (D:S) ratio for TG-2000 is 16:1.

at 800-435-0786.

3. To measure the temperature of a selected area: Press and hold the trigger and point the ther-

mometer at the object to be measured. The dual lasers indicate the approximate diameter of the

measured area. “SCAN,” the measured temperature, and advanced feature data will appear on the

display. The scan icon will blink. Release the trigger after completing the measurement. “HOLD,”

the ﬁnal temperature measurement, and advanced feature data will remain on the display for

1minute.

4. To take more than one temperature measurement, or to locate a hot spot: Press and hold the

trigger, and scan the objects to be measured. The unit will record the maximum, minimum, differ-

ence, and average temperatures.

To perform other functions, refer to “Advanced Features” in the “Using the Features” section.

Limitations

• The thermometer cannot measure through transparent objects, such as glass or plastic. It will

measure the surface temperature of the glass or plastic.

• Steam, dust, smoke, or other particles can prevent accurate measurement by obstructing the unit’s

infrared sensor.

Locating a Hot Spot

To ﬁnd a hot spot, aim the thermometer outside the area of interest, and then scan across with an up

and down motion.

Emissivity

Emissivity is the ability of an object to emit infrared energy. Most objects or surfaces have an emissivity

value of about 0.95. Some objects, such as polished or shiny metallic surfaces, may have much lower

emissivity. Using an infrared thermometer to measure the temperature of such objects will produce

inaccurate results.

• Temperature readings will be inaccurate on highly reﬂective objects.

• Temperature readings will be inaccurate on objects if emissivity is not adjusted properly.

Followmasking and emissivity adjustment procedures.

Failure to observe these precautions may result in injury and can damage the unit.

Masking a Surface to Determine Emissivity

To determine the effect of emissivity on the measurement, cover the surface with masking

tape or ﬂat black paint. (Be sure to use tape or paint that can withstand the anticipated temperature.)

The emissivity of both these materials is about 0.95. Allow time for the tape or paint to reach the tem-

perature of the material underneath. Measure the covered area and a nearby area. The readings should

be about the same. If they are not, the emissivity may affect your measurements.

Compensating for Emissivity

• If the temperature of the surface is known, adjust the emissivity until the unit agrees with the known

temperature.

• If the material of the surface is known, adjust the emissivity according to the Common Emissivities

table on the following page.

• Otherwise, mask the surface as described above. Measure temperature of the masked area with

emissivity set at 0.95. Measure temperature of unmasked surface and adjust emissivity until tem-

peratures agree. Write down emissivity value for future readings on this surface.
