Select Line Voltage
The calibrator comes from the factory configured for the line voltage typically applicable
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 verify the line-voltage setting, note the voltage setting that
you can see through the window in the power-line fuse compartment cover (Figure 2-1).
The permitted 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. To open the fuse compartment, put a screwdriver blade in the tab on the left side of
the compartment and pry until it can be removed.
3. To remove the line-voltage selector assembly, hold the line-voltage indicator tab with
pliers and pull it straight out of its connector.
4. Turn the line-voltage selector assembly to the necessary voltage and reinsert.
5. Make sure to use the correct fuse for the selected line voltage (100 V/120 V, use
5 A/250 V slow blow, 220 V/240 V, use 2.5 A/250 V slow blow). To install the fuse
compartment, push it into position until the tab locks.

Warning
To prevent possible electrical shock, fire, or personal injury:
•
Do not use a two-conductor mains power cord unless you
install a protective ground wire to the Product ground
terminal before you operate the Product.
•
Do not use an extension cord or adapter plug.
Make sure that the Product is grounded before use. The calibrator is shipped with the
correct line-power plug for the country of purchase. If it is necessary to use 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 Calibration.
After you make sure that the line voltage selection is set correctly and that the correct
fuse for that line voltage is installed, connect the calibrator to a correctly-grounded
three-prong outlet.
