Note
The test voltage can be up to 10 % higher than the test voltage
you select.
Select a Ramp or Steady-State Test (1537/1537-II only)
The ramp test function is an automated test that checks insulation for a breakdown.
During a ramp test, the output voltage starts at 0 V and increases linearly (100 V/s)
until it reaches the specied test voltage or until the Tester senses a sudden drop in
measured resistance.
If the Tester senses a sudden drop in resistance:
• Ramp stops
• Tester automatically discharges
If the test successfully meets compliance without breakdown, the result is the same
as a normal insulation test and shows the data.
To enable or disable the ramp function:
1. With the Tester turned on, push
to go to the Ramp test function. When the
ramp test is on, RAMP shows on the display.
Set a Timed Test (1537/1537-II only)
You can control the duration of an insulation test by setting a timer. The time (test
duration) can be set in 1-minute increments up to 99 minutes.
At the end of the elapsed time, the insulation test is complete and the test stops.
To set a test time limit:
1. With the Tester turned on, push
to enter the Timed Test Menu.
2. Push
or to congure the time.
3. Push
to set the time limit.
