CHAPTER 9 : Operation Procedure
9.1 Setup
Before the operation of this instrument, make sure that all Test Parameters have
been set properly according to the Test Parameters Setup Procedures. Also check
the system setting of Remote Control, LCD Contrast, Alarm Volume, Fail Stop,
Single Step, and Memory Lock.
The Power Source to the DUT inputs must be an unbalanced
single phase supply. This means that there is only one HOT or
LINE conductor and the other conductor of the power source
must be at a low voltage reference potential. This low voltage
reference does not need to be physically earth grounded but
should not carry any large voltage potential. The 220 - 240V
US style line power
IS NOT
suitable to be connect to the DUT
inputs. This style of power distribution is a balanced type with
two HOT or LINE conductors.
DO NOT
connect a line
conductor to the N or Neutral terminal of the DUT inputs. This
condition can be very dangerous to the Line Leakage Tester
user.
Be sure to connect the appropriate test leads to the device under test (DUT) or test
fixture, as shown in the diagram below. Please be sure to use a Power Source
which has only one line conductor that is of the balanced type as stated previously.
Be sure to connect the safety ground terminal (on the rear panel) to a suitable
known good ground before energizing this instrument.
