☞
This compensation will be used in all further single or AUTO-TEST R
PE
measurements. It will be active even after switching off and on the GT-
650/GT-900 tester.
☞
CORD and PRCD functions are using their own compensation (the same
for both functions) independent from above described one. See the
information on how to compensate/uncompensated test adapter in
chapters “IEC CORD Test (CORD/PRCD)“ starting on page 39 and “PRCD
Test (CORD/PRCD) (GT-900 only)” starting on page 43”.
☞
Whenever test lead or adapter is changed, the compensation has to be
redone. Wrong compensation will direct influence the test result and may
give wrong judgement for limit.
☞
Compensation is always carried out using test current of 5 A, while second
measurement (self-test) is using selected test current (0.2 or 5.0 A).
How to cancel actual test lead compensation:
Open test loop (disconnect test lead from terminal PROBE 2) and carry out the
compensation as described above. The result >11.00

will be displayed and “C”
symbol will disappear from the top display line.
Limit value setting
Limit value is offered in all functions except in P/I
L
and CLAMP (range 0 … 60 A).
For limit value setting press the “LIM” (or “PAR”, see explanation in each function
separately) menu key, then use the menu keys “+”, “–“, “STD” (Standard) or
“CALC” (Calculation). The menu key F8 “EXIT” can be used to exit limit value
setting display.
☞
In case test result comply with set limit value, the symbol “ ” is displayed and
two short sound signals are present after finishing the measurement. In case
of non-compliance, the symbol “X” is displayed and one longer sound signal is
present after finishing the measurement (see the details in chapter
“ACOUSTIC SIGNAL” on page 77). The limit value is saved as a parameter of
the measurement result and is transferred to PC in case of data transfer.
Start of the measurement

For single measurement press the START key and release it. In this case
measurement time is defined in MENU / SETUP / MEASUREMENT TIMES menu,
see the chapter “SETUP menu” on page 76. Watch elapsed time on displayed bar
graph during the measurement.

For continuous measurements press and keep pressing the START key for at least
2 seconds until “CONT” (continuous) information is displayed. Measurement
time is limited to 5 minutes maximum in this case. Continuous measurement is
available in all functions except in CORD, PRCD and AUTO-TESTS.
