Aux Input Check; Optional Flexi Or Clamp Verification (Combined 1730 And Probe Specifications) - Fluke 1730 Calibration Manual

AUX Input Check

1. Connect 1730 AUX input cables, PN 4395217, to each of the 1730 AUX
inputs.
2. Connect the 1730 AUX input cable BNCs to a BNC-T with a dual banana plug
connector.
3. Plug the dual banana into the calibrator Normal HI and LO, Shield to LO.
4. For all the voltages in Table 11, set the calibrator and check that the values
are between the limits.

Optional Flexi or Clamp Verification (Combined 1730 and Probe Specifications)

This feature of the spreadsheet checks the 1730 combined with current probes.
These tests use the 552x and the 5500Coil. The Test Uncertainty Ratios (TUR) is
typically <2:1. This system can only source 1000 A, consequently, this test will not be
made at full-scale of the Flexi probes.
To connect the customer current probes to the 1730:
1. Connect the VL1730 "N" lead to the calibrator NORMAL LO.
2. Connect the calibrator NORMAL V output to the VL1730 L1+L2+L3 leads.
3. Connect the 5500 coil to the calibrator and the black jack to AUX LO.
4. Connect the red jack to either the AUX jack when <3A is requested or the 20 A
jack when >3 A is requested.
5. Connect all the current probes under test through the 5500Coil with arrows
pointing up for the correct phase match.
6. The spreadsheet Verification tab has an Attached Sensor drop-down list box to
select the probe that is connected.
