Using the Composite Insulator Tester & Software
36
5.2.1.2 Performing a Vertical Scan
A single scan is performed to verify the Composite (Polymeric) insulator.
1. Following the instructions of the Tablet Operator, if the LED is not flashing, press the Push-
button on the Probe (See Figure 15) and place the Insulator Tester against the insulator
nearest possible to the low voltage end of the Composite (Polymeric) insulator, per Figure
16.
2. Then slide forward the Insulator Tester toward the high voltage end of the insulator. A
tone will sound each time a reading is taken at each insulator skirt (shed). The Insulator
Tester may be moved at a speed from 1 skirt (shed) per second up to 10 skirts (sheds) per
second.
3. Remove the Insulator Tester from the insulator and wait for instructions from the Tablet
Operator.
It is important to avoid moving the Insulator Tester backward at any time during the execution
of a scan of the Composite (polymeric) insulators. The adjustable skids can be removed to
accommodate large Composite insulators.

Performing a
Vertical Scan
Place the Probe close to the low
voltage end of the insulator and slide
the Probe forward along the
insulator, moving the Probe from 1
skirt (shed) per second up to 10 skirts
(sheds) per second, toward the high-
voltage end and withdraw the Probe.
