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 5522A 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 3). 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
left side of the compartment and gently pry until it can be removed with the fingers.
3. Remove the line voltage selector assembly by gripping the line voltage indicator tab
with pliers and pulling it straight out of its connector.
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
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.
