environment specifications described in the “General Specifications” section later in this manual. Power Considerations The Meter operates on varying power distribution standards found throughout the world and must be set up to operate on the line voltage that will power it. The Meter is packed ready for use with a line voltage determined at the time of ordering. If the selected line voltage does not match the power that the Meter will be plugged into, the Meter’s line- voltage setting must be changed and replacement of the line fuse may be required. Selecting the Line Voltage The Meter operates on four different input line voltages. The selected line-voltage setting is visible through the window in the line-fuse holder on the Meter’s rear panel. 1. Unplug the power cord. 2. Insert a small screwdriver blade into the narrow recess to the left of the fuse holder and pry it to the right until the holder pops out. See Figure 1. 3. Remove the voltage-selector block from the fuse holder. 4. Rotate the selector block until the desired voltage rating faces outward. 5. Replace the selector block back into the fuse holder. 6. Install the fuse holder back into the Meter and reconnect the power cord. Changing the line-voltage setting may require a different line-power fuse for proper operation. Replacing the Fuses The Meter uses one fuse to protect the line-power input and two fuses to protect current- measurement inputs. Line-Power Fuse The Meter has a line-power fuse in series with the power supply. Table 3 indicates the proper fuse for each of the four line-voltage selections. The line-power fuse is accessed through the rear panel. 1. Unplug the power cord. 2. Insert a small screwdriver blade into the narrow recess to the left of the fuse holder and pry it to the right until the holder pops out. See Figure 1. 3. Remove the fuse and replace it with a fuse of an appropriate rating for the selected line-power voltage. See Table 3. 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.
