4.9 Temperature Monitor Function
Using the key, you can show the monitored temperature on the
LCD, as described below.
■ When the Voltage, Current, Resistance or Pulse
(Continuous Pulse Train or Number of Pulses) Range Is Selected
The reading of a sourced signal remains changed to the temperature
detected by the built-in temperature sensor of the calibrator as long
as the key is kept held down. Thus, you can monitor the room’s
temperature.
■ When the Temperature (Thermocouple or RTD) Range Is Selected
• Pressing the
key once allows you to monitor the electromotive
force (mV) or resistance (Ω) equivalent to the preset temperature.
The monitored value does not reflect the correction made by the
RJ sensor.
• Pressing the
key once again changes to the temperature
detected by the RJ sensor connected to the calibrator or the
internal temperature of the calibrator.
• Pressing the
key one more time reverts to the initial normal
setting mode.
TIP
• In approximately 10 seconds, the temperature monitor function automatically
returns to the initial normal setting mode.
• The reading of internal temperature may become higher than the room’s
temperature because of a temperature rise within the calibrator. With an
external RJ sensor, it is possible to measure the room’s temperature more
precisely.
• For a reading of monitored temperature, the unit symbol (mV, Ω or °C) blinks.
Thus, you can discriminate between a setpoint and a monitored value.
