3 USING THE MULTIMETER
3.1 Preliminary notes
If the battery is weak, the display shows the message “ ”, the battery should,
therefore, be replaced.
Check that the probes are in good condition. If they are damaged, replace them.
The function selector switch must be positioned on the appropriate scale before use.
Do not perform measurements of voltage or current that exceed the maximum capacity
of the instrument.
Properly insert the battery in its compartment.
Always select a capacity which is greater than the value of current or voltage to be
measured.
Make sure the probes are properly connected to the circuit.
Check that the rear cover of the instrument is always closed.
Remove the battery from the instrument when not in use for a long time.
Remember to turn off the instrument after use.

3.3 Measuring DCV and ACV voltage
1. Position the switch at the desired capacity.
2. Connect the red probe into the socket V/and the black one into the COM socket.
3. Select, using the relative measuring scale wheel in relation to the value to be
measured.
4. Connect the other end of the probes to the circuit to be measured.
5. Read on the display the measured voltage.
The polarity of the red probe will be shown together with the Voltage.
Measuring voltage
If the voltage to be measured is not known prior to the operation, position the function
selector at the highest scale.
When "Ol" appears on the display, this means that the voltage is above the maximum
permitted in that scale, consequently the next scale should be selected.
DO NOT ever try to measure more than 1000V as it will damage the instrument.
3.4 Measurement of DCA and ACA current
1. Connect the red button to the socket V/and the black button to the COM socket for a
maximum of 0.5A
2. Select the desired capacity using the switch.
3. Connect the other end of the probes to the circuit to be measured.
4. Read on the display the measured current. The polarity of the red probe will be shown
together with the current.
Measuring current
If the current to be measured is not known prior to the operation, position the function
selector at the highest scale.
When "Ol" appears on the display, this means that the current is above the maximum
permitted in that scale, consequently the next scale should be selected.
A fuse does not protect beyond 20A, the measurement time should be less than 15
seconds if measuring 10A continuously or 20A

3.5 Measuring resistors
1. Connect the red probe into the socket V/and the black one into the COM socket.
2. Select the desired capacity using the switch.
3. Connect the other end of the probes to the resistor to be measured and read the
displayed value.
Measuring resistors
The polarity of the red probe is "+"
When the display shows the symbol "Ol", it can mean that the circuit is open or that the
instrument is out of range: go to the next scale up.
The scale 200Mhas 10 constant digits (1M), the last 10 digits must be subtracted
from the value which appears in the short circuit.
Prior to carrying out measurements of resistors inserted in a circuit, make sure the
power supply to the circuit has been removed and any possible internal capacity has
been discharged.
3.6 Measuring capacitors
1. Position the function selector to "F" before connecting the capacitor, the display should
reset automatically and slowly.
2. Insert the capacitor to be measured in the "Cx" socket and read the value.
Measuring capacitors
The capacitor must be discharged before performing measurements.
NEVER apply current to the "Cx" socket or the instrument will be damaged beyond
repair.
3.7 Measuring inductance
1. Position the function selector to "L".
2. Connect the inductor to the ports "mA" and "COM".
Measuring inductance
When the display shows the symbol "Ol", it can mean that the instrument is out of
range: go to the next scale up.
the inductance may be different due to the different resistance of an inductor itself.
