Measuring Temperature
To measure temperature, set up the meter as shown in
Figure 3-10. The meter begins temperature measurement
in the degree units last used (Celsius °C or Fahrenheit °F).
Once you have selected the temperature function, you can
change units by pressing the blue button. The meter
remembers the units selected until they are changed.
The primary display shows either the temperature or the
message 0PEn (for an open thermocouple condition).
Shorting the input will display the temperature at the meter
terminals.
The secondary display shows any non-zero temperature
offset. This offset is established as a calibrating value
during setup. Refer to Chapter 5 for additional information.
The following pushbuttons cannot be used when taking
temperature measurements:
Frequency ( N)
FAST MN MX ( O M)
Ranging ( R)
WWarning
To avoid the potential for fire or electrical
shock, do not connect the thermocouples to
electrically live circuits.
