[AC test] module is a general, integrated test modules, it consists of a separate 3 -phase
current and 4 phase voltage (this instrument). By setting the corresponding voltage or current
as a variable, assigned a certain change to the variable step length, and selects the
appropriate test methods ( e.g. , manual, automatic, operation stop , operation return ) , easily
test the action value of various voltage, current protection, return value and action time ,
automatically calculate the return coefficient .
(1) Variable selection
Select a single variable or multiple variables simultaneously variable, marking [variable]
column with "√” is OK.
(2) The step length of the variable
The step length can be selected in accordance with the requirements of accuracy. Such
as: voltage step length, such as the current step length.
(3) [each step time]
It is the time interval of each step length for automatic test. Manual test do need to set
this parameter.
(4) [Automatic test ( stop action ) ]
During the output procedures the involved variable change according the set step length
and time, other fixed value not change. Until the relays act, record the action value and action
time. Stop the output, the program automatically returns.
(5) [ Automatic test (action returns ) ]
During the output procedures the involved variable change according the set step length
and time, other fixed value not change. Until the relays act, record the action value and action
time, this moment the device also maintain the output state, and then make the step length
and time interval changes in the opposite direction, until the relay contacts return, the device
terminate the output, recorded return value , the program automatically returns .
(6) [Manual test ( action to stop ) ]
The program continuous output current value, click
