MaxTester Copper Test 125
8 SmartR™ Features
SmartR features, consisting of Pair Detective and FaultMapper, allow you
to determine the condition of the line under test, as well as identify and
locate a variety of common circuit faults.
Pair Detective
The Pair Detective test consists of a series of 10 consecutive individual
tests and applies a high voltage to the line during isolation testing. Before
proceeding with this test, ensure the line is inactive.
At the start of any test, the unit checks for the presence of dangerous
voltage and an active circuit. If dangerous voltage is detected, a dialog box
is displayed to inform you and the test will stop. If an active circuit is
detected, a dialog box is displayed to ask you whether or not to proceed
with the test.
