Using the Handheld Infrared Thermometer

• 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

2-11 for details. The IR thermometer provides an analog output

of 1mV/degree. (0.5 mV/Deg on OS524E)

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

the trigger.

• Moving Surface Scan - Measures the Temperature of Points on a

Moving Surface:

1. Mount the thermometer on a camera tripod and aim at a fixed

point on the moving surface.

2. Pull the trigger and press the key to lock the trigger.

3. If necessary, adjust the emissivity. The thermometer is now set

up for measuring the temperature of a moving surface.

4. To record the temperature profile of the moving surface,

connect the IR thermometer to a strip chart recorder. Refer to

Figure 2-11 for details.

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

• Fixed Point Monitoring Over Time - Monitors the temperature at

a fixed point over time:

It is recommended that you use the ac adapter for long

term measurement of temperature.
