PM7000 Start Guide Issue 1 090608 5
Always make sure that your logger is positioned in a way that ensures it is
mechanically stable. There must be no possibility of the test leads becoming
disconnected from it while they remain attached to any external power source.
For your safety and to avoid damage to the logger do not connect your PM7000
to a live voltage source outside the specified range of 0-600 (+ 10%) Vac. For
measurements between 600 and 1000 Vac please refer to the manual. These are
a special case.
Under no circumstances should you remove the front panel of the logger while
it is connected to a power source.
In line with safety requirements the PM7000 gives correct over range voltage
readings. No danger will arise for an operator relying on any indicated values.
However, this does not remove the possibility that a single fault in the unit
could give misleading results, leading to a hazard for the operator.
