10. Current Measurement
n
First disconnect the power supply to the circuit being measured
and/ or to the load, and discharge all capacitors within that circuit.
n
With the function selector switch (6), select A for currents >660mA
and mA for currents <=660 mA. When measuring current of
unknown magnitude, select the highest measuring range first.
n
Select the function corresponding to the measured quantity by
briefly pressing the yellow multi-function (5) push button.
n
Each time the push button is pressed, alternate switching takes
place between DC and AC. The change-over is acknowledged by
a sound signal.
n
The symbols DC and AC (21)are displayed as per selected function
on the LCD.
n
When selecting a range with the function selector switch (6), the DC
function is always set by default.
n
Connect the multimeter in series with the load, as shown. Ensure
that the connections are tight (with least resistance).
Notes on Current measurement
n
The multimeter must be used only in the power systems, where the
current circuit is protected by a fuse or a circuit breaker of 20 A, and
when the nominal voltage of the system does not exceed1000V
AC/DC.
n
Make the measuring circuit connections mechanically strong and
secure so that they do not accidentally open. The conductor cross
