If you are working in a constantly varying environment, where ambient
temperatures are not constant, do the following:
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.
