Do Not Touch Test Leads while test is in Progress!

15) OUTPUT CONTROL
This control adjusts the output voltage of the tester. Clockwise (CW)
rotation increases output and counterclockwise (CCW) rotation
decreased output. Full CCW is the MIN (minimum) point output and
full CW is MAX (maximum) or 100% of the testers rated output.
Note:
A “Zero Start Interlock” is connected to the output control for
use during Surge and HiPot testing. The user must return the output
control to MIN each time before pressing the Test button (6). In other
words, if the Test button is pressed while the Output control is above
zero the instruments output is disabled until the Output control is
rotated to MIN.
16) FOOTSWITCH CONNECTOR (REAR PANEL)
A footswitch may be connected to this socket which is in parallel to the
Test button. The footswitch will operate the tester in a manner
identical to the Test button, freeing the user’s hands from having to
operate the switch.
17) SURGE/HIPOT SELECTOR. This function, like Function selector
(12), is a relay that selects the type of test, Surge or HiPot, to be performed.
The name of the test chosen is displayed on the lower portion of the CRT
for reference.
For testing windings and stators, it should always agree with the
position of the Function Selector.
Three Phase Selector Switch
This is an optional high-voltage rotary switch that selects which test
lead is hot, open, or ground. If this switch is present on the tester, refer
to Appendix D: Three Phase Operation for a description and
instructions to use this switch for surge testing.
18) LEADS ENERGIZED INDICATOR LIGHT
This indicator light will illuminate when voltage is applied during a
test.
19) TEST LEADS (LOWER SECTION)
Test leads, one red and three black or ground leads, are provided for
contact to the windings. Test leads are insulated to 60kV.
