Specifications
2-3
Ground Bond Floating
(Fixed port 3)
HV output can be set to HV, Low, or Off.
Maximum Voltage is 5kVAC, 6kVDC (TUV list is 5kV)
Maximum Current is 40mA ac or peak dc
WAC maximum add 10 counts extra error
WDC maximum add 2 counts extra error
(Floating Ground)
Ground Bond can be set to Close or Open (Floating
Voltage 1000Vrms or 1400Vpeak AC maximum)
Ground Bond Close, the maximum current is 30Amp
Maximum (add 2mΩ extra error).
1. Twin Port ON for 20mAac, 6mAdc maximum.
Twin Port ON for less than 1/2 duty cycle output only.
WAC:<1000V, >30mA the max. continuous duty time is 120sec.
WDC:<1000V, >8mA the max. continuous duty time is 120sec
The current resolution is 1.2 count for WAC, and 1.6 count for WDC calculated
value.
2. Reference 1.2kV Resistance Load Only.
With standard test lead, to get best accuracy, does not need process OFFSET.
Exceed 1.2kV add 5 counts/kV for WAC mode; add 2 counts/kV for WDC mode.
WDC mode 0mA-0.01mA range, add 5 counts.
WAC mode 0-0.1mA range, add 10 counts.
WAC mode less than 500V add extra 3 counts.
3. Design Specifications
Validation point is 1.25kV with a 250kΩ resistor.
4. 10GΩ ~ 50GΩ without scan unit onl y.
5. Twin Port ON for 25Amps output maximum.
Twin Port ON for less than 1/2 duty cycle output only.
GB Scanner output, add extra 2mΩ error.
For optimal accuracy, use the standard four-wire type for measuring.
If the Offset is lower than 10mΩ, it is over test specification. Using the Offset can add
an extra 5mΩ error.
Electric Strength Test potential for the high voltage terminal was based on circuits in
Measurement Category I (CAT I).
