5.1.5.1 Power-On Self-Test (POST) of the Insulator Tester
During the Power-ON Self-Test, the Infrared transmit/receive interfaces are tested to insure that
the two IR receivers can detect the following 2 states:

Presence of infrared on the two IR receivers,

Absence of infrared on the two IR receivers.
This is implemented the following way in this order:
1. After the memory test (Green LED flashes 4 times), the 2 IR receivers must detect the
presence of infrared,
2. Then the sound beeps and the LED will flash Amber up to 10 seconds till the 2 IR
receivers detect the
absence of infrared.
The operator should manually interrupt the Infrared beams immediately after the start of the
sound to make sure the 2 states of the Infrared are verified. Otherwise, only the “presence of
infrared” state will be verified.
Once the infrared beams have been broken, or after
flashing 10 times, the LED and the tone will turn off.
Once the Insulator Tester has been switched on and the
POST procedure is finished, communications between
the Probe and the Windows-based software on the
Tablet/Laptop must be tested.
