Accuracy Verification Procedure; Voltage Measurement - Fluke 1730 Calibration Manual

Accuracy Verification Procedure

The procedure verifies the Energy Logger accuracy at ambient temperature
23 °C ±2 K (intrinsic error).
A complete accuracy verification of the Fluke 1730 consists of:
•

Voltage Measurement

•
Current Measurement
•
AUX Measurement
•
Optional Flexi or Current Verification
Voltage Measurement
1. Select the basic instrument setup required for all verifications, see page 18.
2. Connect the VL1730 "N" lead to the calibrator NORMAL LO.
3. The 1730 must be on battery power with ≥50 % charge.
4. Connect the calibrator NORMAL V output to the VL1730 L1+L2+L3 leads.
Sequentially set the calibrator to the voltages indicated in Table 9 and check
5.
that the Energy Logger reading is between the limits.
Do this for all ranges indicated in Table 9:
6.
•
set the calibrator to supply a 57.0 Hz sine wave for all voltages
•
wait until each reading has stabilized
The spreadsheet is the first choice for readings. Readings will have more
resolution from the spreadsheet.
7. Push  to select the Energy Logger voltage display.
