DCW Dwell XXX.X s
MXX-X - . - - KV - - - - A
At the end of the dwell cycle when the voltage begins to ramp down, the display will show the
values being updated in real time as follows:
DCW Ramp-down XXX.X s
MXX-X X.XX KV XXXX A
NOTE: In order to see the DCW values measured during the dwell cycle the review key must
be pressed.
IR Ramp Down
The IR ramp down feature allows the IR voltage applied to the DUT, to be reduced linearly
over a specified period at the end of an insulation resistance test.
There are three set up screens associated with this feature that will allow control of Ramp-Up,
Dwell, and Ramp-Down.
The setup screens will appear as follows:
Ramp Up = XXX.X s
Range : 0.1 - 999.9
Use the “Numeric” keys to enter the Ramp Up time setting, then press the “ENTER” key. The
program will store the Ramp Up Time setting and advance to the Dwell Time parameter
automatically. The unit is “second” and 0.1 second per step.
Delay Time= XXX.X s
Range : 0.5 - 999.9 0=Constant
Use the “Numeric” keys to enter the Dwell time setting, then press the “ENTER” key. The
program will store the Dwell Time setting and advance to the Ramp Down Time parameter
automatically. The unit is “second” and 0.1 second per step.
Ramp Down = XXX.X s
Range : 1.0 - 999.9 0=OFF
Use the “Numeric” keys to enter the Ramp Down time setting, then press the “ENTER” key.
The program will store the Ramp Down Time setting and advance to the Frequency parameter
automatically. The unit is “second” and 0.1 second per step.
Press the “EXIT” key to exit from the setting mode to the operation mode if all parameters
have been set.
