relay action can record the action value and action time, then terminate the tester output, the
program automatically returns.
(7) [Manual test ( the action returns ) ]
The program continuous output current value, click

button the variable amount
that increments a step, click [ ▼ ] button the variable amount that is descending a step . If the
relay action can record the action value and action time, now the tester also keep the output
state, the user can manually step changes in the opposite direction as the original tester, until
the relay contacts return the test stop output, and record return value, the program
automatically returns.
(8) [ Open parameters ]
Select the appropriate folder, open the previously saved parameters.
(9) [ Save parameters ]
Save the current parameters to the user-specified folder.
(10) [Default parameters]
Interface will restore to the default parameters, generally: voltage initial 57.73V, current
1A, the phase difference each 120 °, frequency 50Hz and positive sequence.
(11) [Save report forms]
Test results saved to the specified folder, default: DATA / REPORT.
(12) [ View report forms]
View or print the test results from file DATA / REPORT.
(13) [ Positive sequence][ negative sequence ] switch
Program automatically interchanges B, C phase.
(14) [ Sequence component switch]
The program will automatically convert parameter to sequence component model as
follows: U +, U - , U0, I +, I - and I0. The voltage and current are in positive sequence,
negative sequence and zero-sequence, must be access to a three-phase current and
three-phase voltage, can be directly sequential component changes to facilitate component
relay.
