Atec Vitrek-V7x Series - Manual (Page 3)

Accuracy : 2.5%+10mA
Resolution : settable to 0.01A at all levels
Compliance: > 4.5Vrms (6V pk) for all currents
Method 4 terminal measurement
Resistance Max Resistance: Up to compliance V limit at defined test current (4.5ohms max)
Min/Max Limits : Defined for each step, min may be set to none
Accuracy : 2.5%+3mΩ (<2A), 2mΩ (<6.5A), 1mΩ (otherwise)
Resolution : 0.1mΩ (>6.5A), 1mΩ (otherwise)
Resistance Offset Test leads/fixture measurement offset may be universally applied
Test Timing
Ramp Time For AC/DC Hipot: 0 to 99.9sec (0.1sec resolution, 0.05sec accuracy)
Test/Dwell Time 0.1 to 9999sec or user end (0.1sec resolution, 0.15sec accuracy)
Ramp Down May be set to 0sec or same as Ramp time, automatically skipped if no failure and next step
is same AC/DC or IR test type
