How to Select Line Voltage
The calibrator arrives from the factory configured for the line voltage normally
appropriate for the country of purchase, or as specified at the time of your purchase order.
You can operate the Calibrator from one of four line voltage settings: 100 V, 120 V, 200
V, and 240 V (47 Hz to 63 Hz). To check the line voltage setting, note the voltage setting
visible through the window in the power line fuse compartment cover (Figure 2-1). The
allowed line voltage variation is 10% above or below the line voltage setting.
To change the line voltage setting, complete the following procedure:
1. Disconnect line power.
2. Open the fuse compartment by inserting a screwdriver blade in the tab located at the
3. Remove the line voltage selector assembly by gripping the line voltage indicator tab
4. Rotate the line voltage selector assembly to the desired voltage and reinsert.
5. Verify the appropriate fuse for the selected line voltage (100 V/120 V, use 5 A/250 V
How to Connect to Line Power
To prevent possible electrical shock, fire, or personal injury:
•
•
•
The calibrator is shipped with the appropriate line power plug for the country of
purchase. If you need a different type, refer to Table 2-2 and Figure 2-2 for a list and
illustration of the line power plug types available from Fluke.
After you verify that the line voltage selection is set correctly and that the correct fuse for
that line voltage is installed, connect the calibrator to a properly grounded three-prong
outlet.
How to Select Line Frequency
The calibrator is shipped from the factory for nominal operation at 60 Hz line frequency.
If you are using 50 Hz line voltage, you should re-configure the Calibrator for optimal
performance at 50 Hz. To do so, from the front panel, go into SETUP, INSTMT SETUP,
OTHER SETUP, and then push the softkey under MAINS to change the selection to
50 Hz. Store the change. After the instrument is properly warmed up (on for 30 minutes
or longer), you must re-zero the complete instrument. For details, see the section on
"Zeroing the Calibrator" in Chapter 4.

slow blow; 220 V/240 V, use 2.5 A/250 V slow blow) and reinstall the fuse
compartment by pushing it back into place until the tab locks.
Connect an approved three-conductor mains power cord to
a grounded power outlet.
Make sure that the Product is grounded before use.
Do not use an extension cord or adapter plug.
