Select a Ramp or Steady-State Test (1537 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 specified 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
C to go to the Ramp test function. When
the ramp test is on, RAMP shows on the display.
2. Push
D for 1 second to start the test.
Set a Timed Test (1537 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
G to enter the Timed Test Menu.
2. Push
L or M to configure the time.
3. Push
I to set the time limit.
4. Push
D for 1 second to start the test.
