Measuring Dc Current; Measuring Dc Voltage - Voltmaster MCM 1 Mode D'emploi

OPERATING MANUAL
If the measured current exceeds the set range over a long period, this can generate heat which
can impair the operating and function safety of internal circuits.
To prevent discharges and/or incorrect measured values, do not perform measurements on high-
voltage cables (> 600 V).
The measurement range selection is performed automatically
Measuring AC current
Make sure that the test leads are disconnected from the measurement sockets.
Clasp one of the conductors to be measured with the current transformer (tong jaw). Ensure that
the tong is fully closed.
Read off the measured value
Pressing the SEL / NCV button permits frequency read-off.

Measuring DC current

Make sure that the test leads are disconnected from the measurement sockets.
Clasp the conductor to be measured with the current transformer (tong jaw). Ensure that the tong
is fully closed. Ensure correct polarity.
Read off the measured value
The last figure can fluctuate, this is not an error.

Measuring DC voltage

The maximum input voltage in the DCV range is 600 V DC. To prevent danger from electric
shocks and/or damage to the instrument, do not take measurements of voltages over 600 V.
Insert the black and red test leads into the COM and INPUT inputs.
Apply the test leads to the circuit to be measured and read off the value.
