POWERFIX PDM 250 A2
12 - English
AC current measurement
Connect the black test lead to the COM jack [5] and the red test lead to the 10A jack [8]
(for currents > 200mA) or to the mA/Ω/BATT jack [9] (for currents < 200mA).
Set the range selector switch [4] to the desired range in the AC current measuring range A
~
.
If you do not know the current, first set the highest possible measuring range and then reduce
it gradually to the lower ranges until you obtain a satisfactory measurement result.
Connect the test probes [7] in series to the test object.
The measurement result is then indicated on the display [1].
DC current measurement
Connect the black test lead to the COM jack [5] and the red test lead to the 10A jack [8]
(for currents > 200mA) or to the mA/Ω/BATT jack [9] (for currents < 200mA).
Set the range selector switch [4] to the desired range in the DC current measuring range
A
.
If you do not know the current, first set the highest possible measuring range and then reduce
it gradually to the lower ranges until you obtain a satisfactory measurement result.
Connect the test probes [7] in series to the test object.
The measurement result is then indicated on the display [1]. A negative sign is indicated in
front of the measured value for a negative measurement result.
Battery test
Connect the black test lead to the COM jack [5] and the red test lead to the mA/Ω/BATT
jack [9].
Set the range selector switch [4] to the corresponding battery voltage range 1.5V or 9V in
the BATT range.
Connect the red test probe [7] to the positive pole and the black test probe [7] to the
negative pole of the battery.
The measurement result is then indicated on the display [1].
In the measuring ranges BATT 1.5V and BATT 9V, the battery to be measured is charged by
an internal resistance, thus you obtain practical information on the condition and
functionality of the tested battery.
