Testing Fuses
To test the internal fuses of the meter:
1. Turn the rotary selector switch to the Ω position.
2. To test FS1, plug a test lead into VΩHz input terminal and touch the probe to the mA input terminal. The
display should indicate between 0.0 to 0.2 Ω. FS1 (1A 600V - Bussmann BBS-1 recommended). If display
reads higher than 0.2Ω, replace the fuse.
Fuse Replacement
Refer to Figure 1B to replace the fuse:
Figure 1B
Use only a fuse with the amperage, interrupt, voltage, and speed rating specified.
