Power supply socket polarity
Note:
Only use the power supply adapter delivered from manufacturer or distributor of the test
equipment to avoid possible fire or electric shock!
1.6 Maintenance
1.6.1 Replacing fuses
Fuse
M 0.315 A / 250 V, 20 x 5 mm
This fuse protects internal circuitry of low-value resistance function if test probes are
connected to the mains supply voltage by mistake.
Warnings:
 Disconnect any test leads/accessories from the instrument and switch off the
instrument before opening battery/fuse compartment cover. Hazardous voltage
can exist inside the instrument!
 In case a fuse has blown in the instrument, follow the instructions in instruction
manual to replace it!
 Replace any blown fuses with exactly the same type of fuse. Inserting the wrong
fuse into the instrument can impair the operator’s safety and/or damage the
instrument.
