5.3.
DC CURRENT MEASUREMENT
The maximum input DC current is 24mA. Do not measure currents
exceeding the limits given in this manual. Exceeding these limits could
result in electrical shocks to the user and damage to the instrument.
1. Cut off power supply from the circuit to be measured
2. Press the MODE key and select the measuring mode MEAS mA. The symbol "MEAS"
is shown on the display
3. Insert the green cable into the input terminal mA and the black cable into the input
terminal COM
4. Connect the green lead and the black lead in series to the circuit whose current you
want to measure, respecting polarity and current direction (see Fig. 5)
5. Supply the circuit to be measured. The value of current is shown on the main display
and the percentage value with respect to the full scale on the secondary display.
6. The message "-OL-" indicates that the current being measured exceeds the maximum
value measurable by the instrument. The instrument do not perform current
measurements with opposite polarity respect to the connection in Fig. 5. The value
"0.000" is shown at display
