The display can settle in within a range of 0 Ohm (if all cores are short-circuited) up to, for 
example, infinity (in the event of overload) if one core is interrupted. Due to good insulation 
assured by undamaged cables, a test value of 10 MOhm with a tolerance of 20% has been 
established for this rational test procedure.
All values within a range of 8 to 12 MOhm thus indicate that the test has been passed.
In the event of an error, the actual defect, i.e. core short-circuiting, core interruption, core 
reversal or too little insulation, must be determined. Do not touch the connector plugs of 
long extension cables after testing, because they may be electrically charged.

Continuity Test with Extra-Low Voltage
Objects can be tested for continuity with the help of the “Durchgang” (continuity) indicator 
lamp (10). Connect the DUT to the two connector sockets (11) to this end. Testing is 
conducted with safety extra-low voltage of no greater than  33 V AC.

PE Indicator Lamp
Indicates whether or not voltage is present.
Error Lamp
The red error lamp indicates exceeded limit values when measuring protective conductor 
current, insulation resistance, equivalent leakage current, contact current, leakage current 
and differential current.
Piezo Buzzer
In the event that the error lamp lights up in order to indicate that the respective, critical limit 
value has been exceeded, the buzzer also generates an acoustic signal.
