Replacing the Fuse
W 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 the mA measurement display
reading does not respond to current applied to the current (mA)
inputs.
Replace the 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 current
(mA) inputs until it unsnaps from the bottom cover.
5. Replace the fuse with a 0.125 A 250 V fast fuse, Littelfuse
type 2AG.
6. Carefully fit the case top and circuit board assembly
together, making sure that the O-ring is properly seated
between the pressure sensor and the pressure fitting on the
case top. Fit the case bottom onto the case top, engaging
the two snaps near the display end of the case. Reinstall the
three screws.
7. Replace the battery door.
