When measuring 36 V DC / 25 V AC voltage make
•
sure that the wires are not connected to a current
measuring connector and that the function
switch is not in resistance or diode measuring
mode. Always check if you have connected the
wires into the proper connectors.
Be careful when measuring voltage above 50V,
•
especially with high voltage equipment.
Avoid connecting to "live" circuits.
•
Turn off the power in the circuit before
•
connecting the multimeter to measue current
and do not measure above 20A.
Before measuring resistance and diode make
•
sure the circuit is not under power.
Only replace fuses to the same type and value.
•
When replacing the fuse or battery make sure all
•
external power sources are turned off and that
the multimeter is turned off as well.

Maintenance

Handling
Keep the multimeter dry. If it is exposed to
•
moisture wipe it dry immediately. Liquids may
corrode the circuits.
The multimeter must only be used at normal
•
temperatures. High temperatures decrease
the lifetime of electronic devices, damage
batteries and distort and damage plastic parts.
Handle the multimeter with care. A drop may
•
damage the circuits and the case which may
cause incorrect operation.
Protect the multimeter from dust and other
•
dirt that may cause premature abrasion.
Clean the multimeter with a wet cloth. Do not
•
use chemicals, solvents or strong detergents
for cleaning.
Battery replacement (1 x 9V)
Disconnect any external circuits from the
•
device. Turn the multimeter off and remove
the measuring wires from the connectors.
Unscrew the screw at the bottom and remove
•
the bottom cover.
Remove the depleted battery and replace it to
•
a new one of the same type.
Fuse replacement
Disconnect any external circuits from the
•
device. Turn the multimeter off and remove
the measuring wires from the connectors.
Unscrew the screw at the bottom and remove
•
the bottom cover.
Replace the melted fuse to one of the same
•
type and value (5x20 mm, 200 mA / 250 V „F"
type)
