3.4 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.:

3.
• Differential Measurement — Measures the temperature differential
between two spots (the maximum and minimum temperatures
viewed)

• Static Surface Scan – Measures the temperature across a static

Using the Infrared Thermometer/Transmitter
Aim the sensor head at the desired target.
If necessary, adjust the emissivity using the
keys.
Read the temperature.
Aim the thermometer at the first spot.
If necessary, adjust the emissivity.
Aim at the second spot.
Adjust the emissivity of the second spot if required.
To display the differential temperature, press the
"dIF" appears on the display.
Read the differential temperature from the upper display.
Aim the thermometer's sensor head at a starting point.
If necessary, adjust the emissivity.
Slowly move the thermometer's sensor head so that the line of
sight sweeps across the surface. The thermometer measures the
temperature at each point on the surface.
To record the temperature profile across the surface, connect
the IR thermometer to a strip chart recorder that will accept an
analog input matching the analog output of the model OS550
that you have selected.
