PM5A2
6. Setting Tests
The
PM5A2
insulation tester is an extremely versatile instrument that enables automatic performance of several
types of insulation tests, and records them in its internal memory and/or prints the results. Thus, it is necessary to
define the tests to be performed, setting the following parameters before starting the measurement: Test voltage,
Test duration for “TIMER” mode test, Maximum Voltage for step voltage test (SVT), and Minimum resistance limit
for “Pass/ Fail” tests.
6.1. Test Voltage Definition
In order to define the test voltage value, first it is necessary to select one of the voltage adjustment keys:
. These keys enable both the pre-programmed voltage selection (
) and the
and
keys
that increase or decrease the value of the step voltage test for 25 V, 100 V or 500 V, depending on the selected
voltage adjustment key.
As long as the equipment is on, the voltage adjustment key
will be selected. Press the adjustment key
selected again at the moment when leaving the test voltage selection mode.
Note:
Test voltage is the only one parameter that may be modified during tests.
6.2. Selection of the Operation Mode
The
PM5A2
insulation tester has four operation modes: Normal, with TIMER, SVT, and Pass / Fail. The first three
modes are selected using the
key; the “Pass/ Fail” test mode is activated pressing
key.

.2.1 Normal Mode
The normal mode is used in the resistance measurement with unique voltage, without time limit. When selected,
there are no special indications in the display.
