1.2.2 Power
The instrument is shipped in an operational condition and no special installation procedures are required except
to check and/or set the operating voltage and fuse selection as described in the following.
When the instrument is shipped from the factory, it is set for a power line voltage (120 Vac for domestic
destinations). The power line fuse for this setting is 0.50 A Slo-Blo. If the source voltage is to be 220 to 240 Vac,
the fuse must be changed to 0.35 A Slo-Blo (See Figure 1-1).
Figure 1-1: Fuse Holder
The voltage selector and fuse holder are both contained in the covered housing directly above the AC power
connector on the rear panel. To gain access to them, use a small screwdriver or similar tool to snap open the
cover and proceed as follows:
1. To change the voltage setting:
Use the same tool to remove the voltage selector (a small barrel-shaped component marked with
voltage settings). Rotate the selector so that the desired voltage faces outward and replace the selector
back in its slot. Close the housing cover; the appropriate voltage should be visible through the window
(See Figure 1-1).
2. To replace the fuse:
Pull out the small drawer on the right side of the housing (marked with an arrow) and remove the old
fuse. Replace with a new fuse, insert the drawer and close the housing cover (See Figure 1-1).
1.2.3 Power Sensor Precautions
Power Sensor safety precautions, selection, specifications and calibration are detailed in Appendix B to this
publication.
