Using the Handheld Infrared Thermometer 2

2.2.1 Measurement Techniques

You can use the IR Thermometer to collect temperature data in any one of five different ways:

•Spot Measurement — Measures the temperature of discrete objects such as motor bearings, engine exhaust manifolds, etc.:

1.Aim at the desired target and pull the trigger.

2. If necessary, adjust the emissivity using the	and
keys.

3.Read the temperature.

•Differential Measurement — Measures the temperature differential between two spots (the maximum and minimum temperatures viewed)

1.Aim the thermometer at the first spot and pull the trigger. Press

the key to lock the trigger.

2.If necessary, adjust the emissivity.

3.Aim at the second spot.

4.Adjust the emissivity of the second spot if required.

5. To display the differential temperature, press the	key until
“dIF” appears on the display.

6.Read the differential temperature from the upper display.

7.Press the key to unlock the trigger.

•Static Surface Scan – Measures the temperature across a static surface:

1.Aim the thermometer at a starting point and pull the trigger.

Press the key to lock the trigger.

2.If necessary, adjust the emissivity.

3.Slowly move the thermometer so that the line of sight sweeps across the surface. The thermometer measures the temperature at each point on the surface.

4.To record the temperature profile across the surface, connect the IR thermometer to a strip chart recorder. Refer to Figure

2-7 for details. The IR thermometer provides an analog output of 1mV/degree. (0.5 mV/Deg on OS524)

5. After all the data has been taken, press the	key to unlock
the trigger.
