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.
