Description

The Greenlee TG-1000 Infrared 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:

•Laser sighting. The laser indicates the approximate center of the measurement area.

•User-adjustable high and low temperature alarms.

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

measurements.

•Lock mode. Allows long-term measurements without holding the trigger. The laser is 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 °C/°F button.

•To turn the backlight on or off: Press and hold the trigger, and then momentarily press the Lock

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), and Low Alarm Limit (LAL).

Setting Alarm Points

After selecting the HAL or LAL mode, use the °C/°F or Lock button to set the alarm point. A tone will sound if the temperature is higher than or lower than the corresponding set point.

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.

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 background, 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-1000 is 12:1.

1. Refer to “Typical Measurements” for speciﬁc measuring instructions.

2. Test the unit on an object with a known temperature.

•If the unit does not function as expected on an object of known temperature, replace the

batteries.

•If the unit still does not function as expected, call Greenlee for technical assistance

at 800-435-0786.

3. To measure the temperature of a selected area: Press and hold the trigger and point the thermometer at the object to be measured. The laser indicates the approximate center of the measured area. The measured temperature and advanced feature data will appear on the display. 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, difference, 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 temperature 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 temperatures agree. Write down emissivity value for future readings on this surface.
