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 loading capabilities of the 95x at ambient temperatures
≤
30C. For ambient
temperatures above 30C linearly reduce the maximum loading power and current by 1%/C.
Output powers above 200W have a limited test time (e.g., 4 seconds at 250W).
If option HSS-2 is fitted, then the maximum loading is restricted to a maximum of 5mA.
Capacitive loading is only limited by the maximum ramp time (9999.9sec) and the maximum load current, typically
this is a 1F load.
951i, 952i and 956i :
<50mA, reduce by 0.05mA per V above 6000V
953i, 954i and 955i :
<9000V : <30mA, reduce by 0.0067mA per V above 6000V
>9000V : <10mA, reduce by 0.0025mA per V above 9000V
957i :
<10mA, reduce by 0.001mA per V above 10000V
SURGE CURRENT LIMITING AND SHUTDOWN
Impedance Limiting
951i, 952i and 956i : 6.5K
Ω
953i, 954i and 955i : 12.5K
Ω
957i : 24 K
Ω
Peak Shutdown Current
951i, 952i and 956i : 80mA (50mA if DUT GROUNDED set to YES)
953i, 954i and 955i : 40mA
957i : 20mA
Option HSS-2: 5mA
TEST VOLTAGE
Test Voltage Range
951i, 952i and 956i : 20 to 6500V
953i, 954i and 955i : 40 to 11000V
957i : 75 to 15000V
Opt. HSS or HSS-2 : 20 to 5000V
For line voltages below 115V linearly reduce the maximum test voltage by 1%/V
unless Opt. LOLINE is fitted (there is no reduction for Opt. LOLINE).
Test Voltage Accuracy
Except 957i: <(± 0.25% ± 1.25V ± (0.01% + 0.05V) per mA load)
957i: <(± 0.75% ± 2V ± (0.01% + 0.05V) per mA load), add 0.5% above 10000V
Opt. HSS-2: <(± 1% ± 2V ± 1V per mA load)
