1. INFORMATION BULLETIN

The Model CE-IT Insulator Tester is fully automatic and highly sensitive electronic instrument designed to test the
effectiveness of buried pipeline insulators. The CE-IT can also be used to determine isolation condition of
pipelines in road crossing casings.

The Model CE-IT circuit automatically adjusts to the voltage polarity present on the underground piping system
under test. A read out of the test results are displayed in English on the LCD meter:

GOOD: This is displayed when the Model CE-IT determines that the electrical load placed on the
pipe on either side of the isolator is not leaking from one side to the other, so it is able to build a
capacitive load, and therefore determines that the isolator is effective.

BAD INPUT SHORT: This is displayed when the Model CE-IT determines that the electrical load
placed on the pipe on either side of the isolator is leaking from one side to the other, so it is not
able to build a capacitive load, and therefore determines that the isolator is not effective.

BAD INPUT OPEN: This is displayed if the Model CE-IT is not able to electrically load one or
both sides of the isolator. This result indicated a broken lead wire to one or both sides of the
isolator on the pipe system under test.

The entire testing procedure is complete in less than 30 second and audible signal alerts the operator when test
cycle is completed. Although the Model CE-IT is equipped with power start switch, the instrument will
automatically shut off in 10 minutes if not in use, to conserve batteries.

The Model CE-IT is factory calibrated, ready to use and requires no field adjustments.

Functional Features:

• Senses external polarity

• Matches external polarity

• Sense external voltage

• Matches internal voltage reference with external voltage

• Sends charging voltage

• Senses flowing current throughout the testing cycle

• Gives result of test considering the above tested parameters

• Expected battery life exceeds 50 hours
