Manual - 8500A Series Peak Power Meter - Giga-tronics

Operation
2.2.1 PCB-Oriented Voltage Selector and Fuse Holder
The number on the selector card, visible through the window, indicates the nominal line voltage to which
the power meter must be connected.
The line voltages and fuse ratings are:
Line Voltage
Fuse Rating
100/120 Vac, ±10%, 50, 60 or 400 Hz ±5% 1.0 AMP Slo-Blo
220/240 Vac, ±10%, 50, 60 or 400 Hz ±5% 2.0 AMP Slo-Blo
To select a different operating line voltage and fuse, refer to Figure 2-2 and proceed as follows:
1. Open the cover door, rotate the fuse-pull to the left, and remove the fuse.
2. Select the operating voltage by orienting the PC board so that the correct voltage label is on the
top left side.
3. Push the board firmly back into the module slot.
4. Rotate the fuse-pull back into the normal position and reinsert the fuse into the holder. Use care
to select the correct fuse value.
Operating voltage is shown
in the module window
