OPERATION FOR CHECKING INSULATED FLANGE BOLT(S)
A. On single insulated pipeline flange type insulators (where the bolts are insulated only halfway through the
flange), make positive contact with the fixed probe of the Tester to the insulated flange and make positive
contact with the flexible probe to each bolt on the same side of the flange. Read meter for every bolt.
Meter readings will be same as when checking single in-line insulators described above.
B. On double insulated pipeline flange type insulators, make positive contact with fixed probe of the Tester
to one side of a double flange and the flexible probe to each bolt, individually, on the opposite flange side.
Read meter for every bolt. Meter readings will be the same as when checking single in-line insulators
described above.
In the event an insulated flange indicates a definite electrical short, but all bolts indicate they are insulated
properly, the electrical short exists across the flange insulator.
TROUBLESHOOTING
TUNING TEST
The model RF/IT is factory tuned to display the intensity
of the radio signal being received. As the intensity of the signal
increases, the display moves farther to the Left. The RF/IT can
be field tested to check the tuning of the LCD display.
A. Find a single electrical conductor to use for the test. A
length of aluminum bar, or other bare (uncoated) length
of metal, approximately 18” (450 mm) in length will
suffice.
B. Prepare the RF/IT for use, by inserting the probes into
the main instrument.
C.
Turn RF/IT on. Note the LCD shows bars to the “100”
mark at the far Right of the display.
