junction compensation stabilizes.
8.5.1 Using the RJ sensor
Use the RJ-ON key to turn the Resistance Junction Temperature compensation ON or OFF. With the temperature
compensation ON, the display will show the RJ-ON icon and the internal temperature (top right of the LCD).
8.5.2 Temperature Monitor Function
The calibrator offers a temperature monitoring function to observe the voltage value measured from the input terminals. In
the TC measurement mode, pressing the
(T.DISPLAY)
key shows the voltage value measured. Pressing the key again
shows the measured temperature value.
8.6 Measuring Temperature with an RTD
Step 1:
Ensure that the test lead cables are not connected to the instrument under test.
Step 2:
Using the function key
(FUNC)
, select the RTD measurement function.
Step 3:
Connect the test lead cables to the terminals of the instrument under test as shown in Figure 14.
Step 4:
Using the measurement
(RANGE)
key, select the desired range from PT100, PT200, PT500, PT1000, Cu10, and
C50.The selected function, the default measured value, and the unit of measure are displayed.
Notes:
z
The RTD measurement function is unavailable if the TC /RTD source function is ON.
z
The calibrator defaults to the 3-wire connection method when measuring RTD. When using the 2-wire connection
method, pay special attention to linking (shorting) the “COM” and “LOOP” terminals.
7.6.1 Temperature Monitor Function
The calibrator offers a temperature monitoring function to observe the resistance value measured from the input terminals. In
the TC measurement mode, pressing the
(T.DISPLAY)
key shows the resistance value measured from the input terminals.
Pressing the
key again shows the measured temperature value.
8.7 Measuring Frequency
Step 1:
Ensure that the test lead cables are not connected to the instrument under test.
Step 2:
Using the function key
(FUNC)
, select the frequency measurement function.
Step 3:
Connect the test lead cables to the measuring terminals of the instrument under test.
Step 4:
Using the measurement
(RANGE)
key, select the suitable range (500Hz, 5KHz, 50KHz).The selected function, the
measured value, and the unit of measure are shown in the upper part of the LCD.
Note:
The frequency measurement function is unavailable if the frequency, pulse, contact or pressure source function is ON.
