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
