Testing the Fuse
A fuse test is performed each time you turn on the tester. If leads are plugged into the L and
PE terminals, the fuse test is skipped. If a blown fuse is detected, testing is disabled, FUSE
appears on the primary display, and the tester issues a warning beep.
You can also perform a manual check of the fuse.
To manually check the fuse:
1. Turn the rotary switch to
switch setting.
2. Short the leads and press and hold
3. If the fuse is bad, FUSE or Err1 will appear on the display to indicate the tester is
damaged and needs repair. Contact Beha-Amprobe Service for repair (see Contacting
Beha-Amprobe).
