21 AC Line Input A multi-function power input module is used to house the AC line input, main

power switch, and safety fuse. The module accepts a standard AC line cord,

included with the power meter. The power switch is used to shut off main

instrument power. The safety fuse may also be accessed once the line cord is

removed. The instrument’s power supply accepts 90 to 260VAC, so no line

voltage selection switch is necessary.

Caution Replace fuse only with specified type and rating:

1.0A-T (time delay type), 250VAC
