
The output current values can be set in two states, the tester will count time
when press the ENTER button.

There are two ways to record the action time. Firstly, as soon as the tester
receives a single from the relay under test; secondly, the current stop to output,

In this unit, the max output time of max output current is 120s.
Test process
1) Select test item.
2) Set current values.
3) The first state output current value should be smaller than trip current value of relay.
4) The second state output current value should be bigger than trip value of relay, and
makes the relay act.
Press the
Run button, the tester will start to output the first state current value. Press
the ENTER button, the state will change into the second state and start time counting at
the same time. As soon as the tester receives the acting signal from relay or stops to
