Warnings and messages
Before and during the measurement the instrument performs different tests to ensure
safety and to prevent from damaging it. These safety tests include checking for any
external voltage or improper loading of test terminals. If a problem is detected, an
appropriate warning message will be displayed. Warnings and protective measures are
described in this chapter.
Voltage between test terminals C1/H and C2/E is higher than
allowed (>10 V). Disconnect the test leads and check why an
external voltage was detected!
Output was overloaded or test current abruptly fall down.
Overload can be caused by high spurious earth current. In this
case it is recommended to decrease the output power. See
chapter
Output current is too low. A too low current can be caused
because of bad connection or high probe resistance.
