Temperature Measurement Configuration
This section contains information to help you configure the meter for
making temperature measurements. To measure temperature, you will
need a temperature transducer. Transducer descriptions and specific
comments about their usage are given on page 263. The meter supports
three general categories of transducer:
•
RTD (Resistive Temperature Device)
•
THERM (Thermistor)
•
T/C (Thermocouple)
The meter supports specific types of transducers in each category:
RTD’s

Once you set the measurement units, probe type, and transducer type,
the setting is stored in
non-volatile memory. This makes the last probe
type used the default probe type.
Measurement Units
•
The meter can report temperature in
°
C (Celsius),
°
F (Fahrenheit),
or K (Kelvins).
•
The measurement units set are stored in non-volatile memory.
•
Front Panel Operation: Set the units under the
2: UNITS
command
in the TEMPerature menu.
•
Remote operation: Set the units using the following command:
UNIT:TEMPerature {C|F|K}
