3-13. Resistance Calibration
The equipment listed in Table 3-14 is required for calibration of the resistance function.
(The equipment is also listed in the consolidated table, Table 3-1.)
Table 3-14. Test Equipment Required for Calibrating Resistance
Quan. Manufacturer Model Equipment
1 Fluke 5500A/LEADS Test lead set
1 Hewlett Packard 3458A with -002 option DMM
1 Fluke 742A-1M Resistance Standard, 1 M Ω
1 Fluke 742A-10M Resistance Standard, 10 M Ω
1 Guildline 9334/100M Resistance Standard, 100 M Ω
1 Guildline 9334/1G Resistance Standard, 1G Ω
Proceed as follows to calibrate the resistance function:
1. On the HP 3458A, perform the ACAL (autocal) ALL and MATH NULL functions as
described in the HP 3458A user documentation.
2. Verify that the UUT (Unit Under Test) is in Standby.
3. Follow the prompt on the Control Display to connect the DMM to the UUT for
4-wire ohms measurement as shown in Figure 3-10.
4. Press the GO ON softkey and wait for the internal calibration steps to complete.
5. Measure and enter the values into the UUT for calibration steps 1 through 8 in Table
3-15 as prompted.
6. Disconnect the DMM from the UUT, and connect it to the Fluke 742A-1M
Resistance Standard as shown in Figure 3-11. Scale the 1 MΩ DMM range to the
Resistance Standard as described in the HP3458A user documentation.
7. Connect the UUT to the DMM in a 2-wire ohms configuration as shown in
Figure 3-12.
8. Measure and enter the values into the UUT for calibration steps 9 through 11 in Table
3-15 as prompted.
9. Disconnect the DMM from the UUT, and connect it to the Fluke 742A-10M
Resistance Standard. Scale the 10 MΩ DMM range to the Resistance Standard as
described in the HP3458A user documentation.
10. Connect the UUT to the DMM in a 2-wire ohms configuration as shown in
Figure 3-12.
11. Measure and enter the values into the UUT for calibration steps 12 and 13 in Table 3-
15 as prompted.
12. Disconnect the DMM from the UUT, and connect it to the Guildline 9334/100M
Resistance Standard as shown in Figure 3-13. Scale the 100 MΩ DMM range to the
Resistance Standard as described in the HP3458A user documentation.
13. Connect the UUT to the DMM in a 2-wire ohms configuration as shown in
Figure 3-12.
