Performing A Ramp Test - Fluke 1550 User Manual

Performing a Ramp Test

The Ramp test is an automated test that checks the insulation for a
breakdown. During a Ramp test, the output voltage starts at 0 V and
increases linearly until it reaches the specified test voltage (500 V, 1000 V,
2500 V, or 5000 V) or until a sudden drop in measured resistance) is
detected. Then the Ramp stops, the test voltage drops to zero, and the
voltage at the breakdown point is stored in memory on the Meter.
To perform a Ramp test:
O
1. Press to turn on the Meter.
The Meter will be in TEST VOLTAGE mode with a 500 V default test
voltage.

2. Press or
2500 V, and 5000 V). The selected test voltage appears in the upper-right
of the display.
The nominal test voltage is 5-10 % higher than the voltage you select.
3. Connect the probes to the circuit you want to test.
To avoid possible electric shock or personal injury: before and after
testing, confirm that the Meter does not indicate the presence of a
hazardous voltage at the terminals. If the Meter beeps continuously
and a hazardous voltage is shown on the display, disconnect test
leads and remove power from the circuit under test.
