6.2 Fuse Replacement

If a current greater than the rated value flows when the instrument is in the current-

measurement range, a protection fuse may blow.

If this happens, replace that fuse. The instrument contains the following types of fuses.

W ARNIN G

• Be sure to disconnect the instrument from the circuit under test and test leads before

replacing the fuses.

• Turn the function switch to OFF (turn off the power) .

• Do not operate the instrument with the casing left open.

• In order to avoid damage to the instrument or any possible accident, use fuses of the

specified rating.

Fuse rating:

F1 M-8926 (440mA/1000V, SIBA GmbH & Co. KG, 50 210 06.0.44)

F2 M-8927(10A/1000V, SIBA GmbH & Co. KG, 50 199 06.10)

High breaking capacity type

To replace the fuse:

1) Remove the screw on the back of the casing.
2) Remove the back cover.
3) Remove the blown fuse from the fuse holder.
4) Install a new fuse in the holder.
(Make sure the fuse rating.)
