Lower Display Mv Source Tests; Lower Display Voltage Source Tests - Fluke 724 Calibration Manual

Lower Display mV Source Tests

1. Press M on the UUT until SOURCE appears on the lower display; then press V
until mV appears on the lower display.
2. Set the HP 3458A to measure dc voltage in the 200 mV range.
3. Connect the UUT to the HP 3458A as shown in Figure 7.
4. Use the arrow keys on the UUT to set the UUT output to the current values in Table
17 and verify that the HP 3458A readings are within the limits shown.
5. Press Mon the UUT to disable the sourcing function.

Lower Display Voltage Source Tests

1. Press M on the UUT until SOURCE appears on the lower display; then press V
until V appears on the lower display.
2. Set the HP 3458A to measure dc voltage in the 20 V range.
3. Connect the UUT to the HP 3458A as shown in Figure 7.
4. Use the arrow keys on the UUT to set the UUT outputs to the currents in Table 18
and verify that the HP 3458A readings are within the limits shown. You can use a
lower voltage range on the HP 3458A to verify the 0 V range.
