Programming An Insulation Resistance (Ir) Test - QuadTech Sentry Plus Series Instruction Manual

The In-Rush current limit for the DC hipot test is a low limit which is monitored during initial charging of the device
under test. When activated (other than Off), current below the programmed value is considered to be a Fail
condition. This current monitoring is generally used to check that the charging current to the device exceeds a
specified value (> programmed limit), thus ensuring that the device is properly connected to the tester.
2.7 Programming an IR (Insulation Resistance) Test
This test is applicable to the Sentry 30 Plus instrument. With the instrument in 'stand-by' status,
press [F1] = PROGRAM. If continuing the 5-step example from ¶2.6, you are already in
program mode and on the AC test mode page. This example shows a GC test as Step1, an AC
test as Step 2, a DC test as Step 3 and how to program an IR test in Step 4. Follow the
arrows (!) on the right side of this diagram to program the individual IR test parameters.
