• 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.
