22
SPECIFICATION
Test Voltages (d.c.): 500 V, 1000 V, 2500 V & 5000 V.
50 – 5000 V variable in 25 V steps.
Voltage Accuracy (0 °C to + 30 °C): ±2% ±1 V of nominal test voltages (load resistance >100 MΩ).
±25 V for test voltages <500 V
Insulation Range: 100 kΩ to 1 TΩ analogue.
10 kΩ to 5 TΩ digital.
Insulation Accuracy (0 °C to + 30 °C): ±5% 1 MΩ to 1TΩ at 5 kV.
±5% 1 MΩ to 100 GΩ at 500 V.
±5% 1 MΩ to 10 GΩ at 50 V.
±20% 100 kΩ to 1 MΩ and 1 TΩ to 5 TΩ at 5 kV.
±20% 100 kΩ to 1 MΩ and 100 GΩ to 500 GΩ at 500 V.
For extended temperature range –20°C to + 50°C the percentage error doubles.
Short Circuit Current: 2 mA nominal.
