Preface
Dear Customer,
we like to congratulate you on the
purchase of your new digital multimeter!
You have chosen a product which
combines deliberate technical features
with an appealing design.
Please read this manual conscientiously
and carry out the given instructions before
and while you are using your new device.
Capability Characteristics
This portable multimeter is ideal with its
compact design.
Measures electric current, voltage and electric
resistance.
It performs diode, transistor and continuity
testing.
Test leads and a transistor test adapter are
included.
Security Advices
Before using the device, please check it for any possible damages. In case of damage do not operate it.
Do not measure voltage sources which exceed 600 V.
The device may not become subject of mechanical stress and should not be exposed to humidity or high
temperatures.
Contamination of the sensors can falsify the result of measurement.
If the results are out of the testing range while it is adjusted manually then the display shows “1”. In
this case change the testing range.
If the voltage of the device operating batteries is to low exchange it.
Clean the device with a dry and soft cloth only.
Caution! Should the device itself get damaged, please let the repair to the manufacturer or to a qualified
service agent.
Please dispose packaging materials properly and do not let play children with it.
The device itself is no toy either. Do not let children play with it too.
