5.3 Fuse Replacement
Please replace the fuse according to the following steps:
Shut down the instrument power supply.
Disconnect the test lead from the circuit being measured, and remove it
from the instrument.
Loosen the bolts fixing the back cover with a PH1 screwdriver, and take
off the back cover.
Take off the old protective tube, and replace with a new one of the same
type or specification (F630mA/250V).
Install the back cover, and tighten the bolts.
Only fuse with specified ampere, fuse rated value, voltage
rated value and fusing speed could be used.
To avoid any electric shock or personal injury, before opening the
back cover or replacing the Fuse, please shut down and check to
guarantee that the test lead has disconnected from the
