5.1.5.1 Power-On Self-Test (POST) of the Probe
Upon switching the Probe on, the POST process commences and the infrared detectors are
verified.
The power-up sequence for the 3782091C/x Composite Insulator Tester is described below:
1. Apply power by sliding the switch located on the side of the Probe, underneath the Switch
Cover, toward the RS232 connector
2. The LED will flash Amber once
3. The LED will then flash Green four times
4. After which, a long tone begins and the LED will flash Amber 10 times or less if the IR
sensors (IR1, IR2) are manually interrupted.
5. If the Red LED begins flashing, then the Probe’s infrared sensors are being obstructed.
Ensure that there are no obstructions and that the lenses are not fouled. The Red LED will
stop flashing the moment the infrared beams are unobstructed.
To fully check the 2 infrared beams (IR1, IR2), make a hand-pass through the beams, inside the
sled near the Probe at the beginning of the long tone.
Once the infrared beams have been broken, or after flashing 10 times, the LED and the tone will
turn off. The Probe is in “sleep” mode.
Once the Insulator Tester has been activated and the POST procedure is finished, communications
between the Probe and the Windows-based software on the Tablet/Laptop must be tested.
