This adjustment procedure requests approximately:
•
1000
Ω
•
2000
Ω
•
4000
Ω
The actual value used must be entered.
1.
For the 0
Ω
connection, connect a short to the 4 terminals for 4W RTD/
Ω
.
2.
For the 5522A connections, see Figure 15 for connections.
3.
Follow the steps in the menu.
4.
Use the 5522A to enter 4000
Ω
(nominal) and enter the actual value calculated as
described above.
5.
Repeat for all calibration points.
Step 12: TC SOURCE, TC mV Source Adjustment
The adjustment of the TC Source output range is similar to the first part of the voltage
source calibration. Use the test leads and a DMM for this procedure.
Use a copper TC mini-plug cable with low thermal EMF jacks on the other end to
connect the Product to the DMM. Make sure the polarity is correct. Set the DMM to read
dc volts.
Enter
12
at the PC. The calibration of the TC source output range is similar to the first
part of the voltage source calibration. The Product outputs two calibration points, after
the output becomes stable, enter the values on the PC.
After the mV reading on the DMM is entered, you are prompted to enter the second
calibration point.
