POWERFIX PDM 300 A1
First use
Never exceed the maximum permissible input values.
Before measuring, remove the cover of the test lead and switch on the multimeter by pressing the
on/off button [10]. The multimeter has an auto power OFF function and switches itself off
automatically after longer periods of non-use. However, you can also switch off the multimeter
directly with the on/off button [10].
You obtain a more accurate measurement result if you use the smallest possible measuring
range.
Overflow indicator
The multimeter has an overflow indicator. If a measured value exceeds the range limit of the
selected measuring range, "0L" is indicated on the display [1]. In this case, switch to a higher
measuring range immediately if possible, or remove the test probes [7] from the test object.
