2-4. Selecting 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 5500A Calibrator from one of four line voltage settings:
100 V, 120 V, 200 V, and 240 V (47 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. Remove the fuse compartment by following the first two steps in "Replacing the
2. Remove the line voltage selector assembly by gripping the line voltage indicator tab
3. Rotate the line voltage selector assembly to the desired voltage and reinsert.
4. Verify the appropriate fuse for the selected line voltage (100 V/120 V, use

2-5. Connecting To Line Power

To avoid shock hazard, connect the factory supplied three-
conductor line power cord to a properly grounded power outlet.
Do not use a two-conductor adapter or extension cord; this will
break the protective ground connection.
Use the rear-panel ground terminal for a protective grounding
wire if there is any question as to instrument earth grounding.
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.
