23. High Voltage Guidelines (4250 only)
Use the following considerations to determine high voltage specications:
● Customer needs, engineering necessities, or manufacturer’s specications for wires and connectors.
Note: Do not confuse the rated running voltage with a maximum hipot value.
● Voltage applied to a cable which may be limited by the spacing between pins in a connector and the separation of
the conductors in a cable.
● Available high voltage selections for the Insulation Resistance Settings (see page 21)  see the table below.
● Highly capacitive cables that the amount of high voltage that can be applied to the cable.
■ HV Insulation Resistance Table
The “HV Insulation Resistance” settings are limited by the high voltage settings. The table below shows the available
Insulation Resistance settings at each of the high voltage settings.
Voltage Min IR (Meg) Max IR
100 V 10 100
200 V 20 200
300 V 30 300
400 V 40 400
500 V 50 500
600 V 60 600
700 V 70 700
800 V 80 800
900 V 90 900
1000 V 100 1000
■ HV Insulation Resistance Guidelines
IR Settings may be based on any of the following factors:
● Contamination: Fingerprints and mold release on your DUT may require you to lower the IR threshold.
● Humidity: A humid environment can aggravate the eects of contamination between contacts and aect insulation.
■ High Voltage Duration:
Insulation Resistance Duration may be set using the following guidelines:
