3 Making Measurements
To measure temperature, follow these steps:
1 Set the slide switch to the M position to disable the
output.
2 Turn the rotary switch to the position.
3 Press and hold for more than 1 second to select
temperature measurement.
4 Plug the thermocouple adapter (with the thermocouple
probe connected to it) into the positive and negative input
terminals (Figure 3- 4 on page 53).
5 Touch the surface to be measured with the thermocouple
probe.
6 Read the display.
If you are working in a constantly varying environment,
where the ambient temperature is not constant, follow these
steps:
1 Press to select 0 °C compensation. This allows a
quick measurement of the relative temperature.
2 Avoid contact between the thermocouple probe and the
surface to be measured.
3 After a constant reading is obtained, press to set
the reading as the relative reference temperature.
4 Touch the surface to be measured with the thermocouple
probe.
5 Read the display for the relative temperature.
