Replacing a Fuse
! Warning
To avoid personal injury or damage to the
calibrator, use only a 0.125A 250 V fast fuse,
Littelfuse
®
2AG.
Fuse F1 is probably blown if:
• in the mA input mode, the calibrator always reads 0.000,
even with a signal applied.
• in the mA output mode, with a short across the mA OUTPUT
jacks, OL is flashing on the display.
Fuse F2 is probably blown if:
• in the V output mode, with the test leads removed from the
calibrator, the display flashes OL.
• in the V input mode, the calibrator always displays OL, even
with a signal applied that is within the measurement range.
Replace a fuse as follows:
1. Remove the test leads and turn the calibrator off.
2. Remove the battery door.
3. Remove the three Phillips-head screws from the case
bottom and turn the case over.
4. Gently lift the top cover from the end nearest the input/output
jacks until it unsnaps from the bottom cover.
5. Replace the blown fuse with a 0.125 A 250 V fast fuse,
Littelfuse
®
2AG. Fuses F1 and F2 are the same type.
6. Fit the top and bottom covers together, engaging the two
snaps. Make sure that the gasket is properly seated.
Reinstall the three screws.
7. Replace the battery door.
