MEASURE OFF Key
Turns on/off the MEASURE mode. Turning off the mode causes the
measured value shown on the LCD to disappear. If the MEASURE
mode is not in use and therefore turned off, the power to the measure-
ment circuit within the calibrator is also turned off. This strategy saves
on battery power if the calibrator is running on batteries.

HOLD Key
Holds the measured value being displayed. Also used to start CPM or
CPH measurement or communication.
10 MEM Key
Used to turn on/off the memory function.
SOURCE Mode – Functions for Generation
11 Output Terminals
These terminals are common to all of the source functions.
12 Function Selector Switch
Selects a source function and its range.
13 RANGE Key
Used to further select from range options within the selected function.
• If you have selected the 100 mV TC range, use this key to select the
voltage output or the type of thermocouple, as the key cycles through
the 100 mV, K, E, J, T, R, B, S, N, L and U options.
• If you have selected the 400
Ω
RTD range, use this key to select the
resistance range or the type of RTD, as the key cycles through the
400
Ω
, Pt100 and JPt100 options.
• If you have selected the PULSE range, use this key to select the
frequency range, as the key cycles through the 500.0 Hz, 1000 Hz
and 10 kHz options.
14 SOURCE ON Key
Turns on/off the source output.
15 PULSE SET Key
If you have selected the PULSE range, use this key to cycle through
the frequency, amplitude and pulse count options for pulses being gen-
erated.
16 TEMP Key
Allows you to monitor temperature by selecting from the room tempera-
ture (
°
C), reference junction temperature (
°
C), thermocouple (mV) and
RTD (
Ω
) options.
