8845A/8846A Users Manual does not match the power the Meter will be plugged into, then the Meter's line voltage setting must be changed and the line fuse possibly replaced. Selecting the Line Voltage The Meter will operate on any one of four different input line voltages. The set line voltage is visible through the window in the line fuse holder, found on the Meter's rear panel. To change the line voltage: 1. Remove the power cord from the Meter. 2. Insert a small screwdriver blade in the narrow recess to the left of the fuse holder and pry to the right until the holder pops out, as shown in Figure 2-1. 3. Remove the voltage selector block from the fuse holder. 4. Rotate the selector block until the preferred voltage rating faces outward. 5. Replace the selector block back into the fuse holder. Changing the line voltage setting may require a different line-power fuse for proper operation. Check Table 2-1 for the appropriate fuse for the selected line voltage. With the voltage set and appropriate fuse installed, replace the fuse holder back into the Meter and reconnect the power cord. Replacing the Fuses The Meter employs fuses to protect both the line-power and current measurement inputs. Line-Power Fuse The Meter has a line-power fuse in series with the power supply. Table 2-1 indicates the proper fuse for each of the four line voltage selections. This fuse is located on the rearpanel. To replace this fuse: 1. Unplug the power cord from the Meter. 2. Remove the fuse holder by inserting a small screwdriver blade in the narrow recess to the left of the fuse holder and pry to the right until the holder pops out as shown in Figure 2-1. The Meter is shipped with a replacement fuse of the same rating as the fuse installed in the fuse block. 3. Remove the fuse and replace with one rated appropriately for the selected line-power voltage. See Table 2-1. 4. Replace the selector block back into the fuse holder. XW Warning To avoid electric shock or fire, do not use makeshift fuses or short-circuit the fuse holder. Use only Fluke fuses 2-4
