2.4 Programming a Ground Continuity Test
This test is applicable to the Sentry 10, 20 and 30 Plus instruments. A Ground Continuity (GC)
test is usually done first to verify the ground connection before high voltage is applied in the AC
& DC Hipot tests. With the instrument in ‘stand-by’ status, press [F1] = PROGRAM. The AC
test mode programming screen is displayed. Follow the green arrows (!) on the right side of
this diagram to program the individual GC test parameters.
