- Replace the battery with another one of the same type (9V battery). Be careful
to connect the leads the right way round.
Always close up the housing carefully and tighten all the fastening screws
before starting to use the multimeter again.
Use a damp cloth and a mild cleaning agent to clean the device. Never use
abrasives or solvents
Using the multimeter
A. Measuring a DC voltage:
Important: Never exceed the permissible measuring range of 600 V DC!
Never touch a circuit or components in a circuit if the voltage being
measured is above 25 V AC or 35 V DC!
1. Connect the red test cable to the "VΩmA" jack and connect the black one to
the "COM" jack.
2. Set the rotary switch to the relevant measuring range "V
– straight line". If
there is any doubt at first regarding the measuring range, start with greatest
measuring range and then reduce it a little at a time until the ideal measuring
range is found. If any measured value appears on the display although the test
probes have not yet been connected to the object, this can be attributed to the
sensitivity of the measurement input and of no importance.
3. Connect the test probes to the measurement object. If an "-" appears on the
display, this indicates that you have reversed the polarity.
4. Now read the measured value off, retaining it if necessary with the "Hold"
button.
B. Measuring an AC voltage
Important: Never exceed the permissible measuring range of 600 V AC!
Never touch a circuit or components in a circuit if the voltage being
measured
exceeds 25 V AC!
1. Connect the red test cable to the "VΩmA" jack and connect the black one to
the "COM" jack.
2. Set the rotary switch to the relevant measuring range "V
– wavy line". If at
first there is any doubt about the measuring range, start with the highest
