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 gives a
quick measurement of the relative temperature.
2 Avoid contact between the thermocouple probe and the
measurement surface.
3 After a constant reading is obtained, press to set
the reading as the relative reference temperature.
4 Touch the measurement surface with the thermocouple
probe.
5 Read the display for the relative temperature.
