95x Series Hipot Tester Specifications
Specifications are valid at the 95x terminals for 1 year at ambient temperatures within ±5C of calibration temperature (add 5% of accuracy specification per C outside of this). All specifications are relative to the calibration standards used. Add ½ digit to all accuracies for displayed results (results available with enhanced resolution from interfaces).

LOADING CAPABILITY
The listings below show the maximum loading current and power capabilities of the 95x at ambient temperatures ≤30C. For ambient temperatures above 30C linearly reduce the maximum loading current and power by 1%/C.
For frequencies above 100Hz other than 400Hz, the user should linearly interpolate using the <100Hz and 400Hz capabilities shown in the applicable listing.
Where both a current and power limit is shown, the most stringent limit applies.

Accuracy
Add Test Current and Voltage Accuracies as percentages
Examples at 50 or 60Hz –
0.1ohm at 1A : 1% + 0.53% = 1.53%
0.1ohm at 10A : 0.55% + 0.5% = 1.05%
0.1ohm at 40A : 0.51% + 0.5% = 1.01%
0.01ohm at 1A : 1% + 0.8% = 1.8%
0.01ohm at 10A : 0.55% + 0.53% = 1.08%
0.01ohm at 40A : 0.51% + 0.51% = 1.02%
