Fluke 1750 Calibration Manual page 23

Calibration is controlled by 1750 Cal Wizard Software (Cal Wizard), which
communicates with the Recorder over Ethernet. Cal Wizard steps through the calibration
procedure, with instructions for making cable connections, setting the correct sources,
and finalizing the calibration.
The following steps detail the calibration adjustment procedure:
1. Connect the Recorder and the PC to the network with an Ethernet cable. This can
either be by direct connection or via a hub on an Ethernet network.
2. Connect ac power to the Recorder. Make sure the Recorder, calibrator, and PC
running Cal Wizard software are all properly connected to safety ground.
3. Allow the calibrator and Recorder to warm up (30 minutes for the Recorder). If
necessary, run Ohms-Cal or Zero-Cal on the calibrator.
4. Reset the calibrator. Confirm the following calibrator state: 0 V, Standby (OPR LED
off), EARTH Off (LED off), and EXGRD Off (LED off).
5. Start Cal Wizard.
6. With Cal Wizard, select the Recorder to be calibrated, and then click Connect.
If the Recorder is password protected, the correct password must be
supplied to continue.
7. Click Next.
8. Follow the on-screen instructions to perform each of the four calibration types. If any
of these procedures report a failure, the Recorder must be returned for inspection and
service. See Contacting Fluke.
9. If all calibrations are successful, click Apply to store the correction values in the
Recorder memory. This will take up to a minute to complete.
10. Click Finish. The Recorder will shut down and restart using the new calibration
values. This may take several minutes.
This concludes Recorder calibration.
