2.2 Fuse Requirements
An AC input fuse is necessary when powering the instrument. The fuse is located at the back of the instrument. If
the fuse needs to be replaced, ensure the AC input power cord is disconnected from the instrument prior to
replacement. Refer to Table 2.1 for fuse requirements.
Before replacing fuse, disconnect the AC power cord first to prevent electric shock.
Only use same rating of the fuse. Using a dierent fuse may damage the instrument.

2.2.1 Fuse Replacement
1. Check and/or Change Fuse
• Locate the fuse box above the AC input in the rear panel.
• With 2 fingers, press both le and right sides of the fuse box and pull it out.
• Check and replace fuse (if necessary) for the required line voltage operation.
2. Check and/or Change Line Voltage
Line voltage is selected and configured via fuse holder orientation.
• The beige colored piece is the fuse holder and line voltage selector. To change the line voltage
configuration between 110 V and 220 V, pull this piece out of the fuse box and rotate it 180 degrees.
• Re–insert the fuse box. The configured line voltage is visible through an opening visible at the end of
the holder. It will display either 110 or 220. If neither of these labels is shown, pull out the fuse holder
and turn it until it shows the line voltage configuration desired.
Figure 2.1: Change Line Voltage Configuration
Do not connect power to the instrument until the line voltage is configured correctly.
Applying an incorrect line voltage or configuring the line voltage improperly will
damage the instrument and void all warranty.
Disassembly of the case by any unauthorized persons will void the warranty.
