Voltage Test
1.
Place voltage limiter on something insulated from ground and
drilling unit (such as dry board or tire), but near frame of
drilling unit.
2.
Clip one lead to frame.
3.
Clip other lead to one voltage limiter mount.
4.
Move simulator switch to "voltage" and press test button.
5.
Watch screen and lights above display on strike system.
•
All lights should turn on.
•
Alarm and strobe should turn on.
•
Voltage "V" should show 90-110%.
It is normal for simulator voltage levels to drift below strike level.
When this happens, light in triangle should go off and alarm and
strobe should stop working. If the level drifts above strike level
again, light, alarm, and strobe should be turned on again.
