The step and contact voltages are calculated using the following formulae according to the values of 

the erratic voltages:

 If the erratic voltages are less than 10% of the voltage to be injected:

 Press the button 

 to start the sequence. The sequence consists of:

 

A.- Acoustic signal indicating the start of the test.

 

B.- Connection of the current output contactor.

 

C.- Measurement of erratic voltages.

 

D.- Test at 25 V 

~.

 

E.- Injection of at least the required current.

 

F.- Voltage increase if the desired current is not reached.

 

G.- Current injection with 180º phase shift.

 

H.- Sample of results.

The test sequence can be cancelled at any time:

 

- By pressing the button 

.

 

- Changing the position of the safety key to 

TEST DISABLED

.

 

- Interrupting wireless communication with the Smartphone.

 

- Disconnecting the thermo-magnetic switch.
