7.1.1 Ground Terminal
Wing nut ground terminal for connecting the safety ground lead to earth ground (connected to the instruments
housing and the ground pin from the mains connector, there is no measuring or AC supply functionality)
A separate green/yellow earthing cable is provided for the purpose of safety grounding the instrument. The Safety
Ground cable should be connected to the Earthing Screw on the left side of the front panel of the Midas micro at
one end and to the station grounding system at the other end.
For safety reasons the earth cable should be the FIRST lead to be
connected to the set and the LAST to be disconnected.
7.1.2 Ventilation Slots
The ventilation slots allow air cooling with the integrated fans.
Do not block any of the ventilation slots. Keep clean for proper cooling.
7.1.3 High Voltage Output
Plug receptacle for connecting the high voltage output cable (grey) respectively the test object
7.1.4 Emergency Stop Button
When the Emergency Stop Button is pressed the test is automatically terminated (high voltage is switched off and
it is not possible to switch the high voltage on until the button is released)
The emergency stop switch is directly integrated in the safety interlock circuit
(hardwired) without any interaction of the built-in CPU or software.
7.1.5 Low Voltage Point V
4 mm plug for connecting all parts which capacitance shall not be measured (with this reference “v” potential the
HV transformer and the entire HV circuit is enclosed Guard. It is also the low voltage point of the HV supply,
NOT the system earth)
7.1.6 Measuring Input HV GND
Plug receptacle for connecting the low voltage test lead HV GND. This input is used for measuring grounded
specimens. The maximum input current is limited to 200mA.
7.1.7 Measuring Input A
Plug receptacle for connecting the low voltage test lead A. The maximum input current is limited to 200mA.
7.1.8 Measuring Input B
Plug receptacle for connecting the low voltage test lead A. The maximum input current is limited to 200mA.
