  • Page 106 2.6.12 Start Wait The Start Wait time is a delay time – after connection to the device is made and before current is applied to begin the ground bond test. This feature is normally used in a probing application. For example: If a 2 second start wait time is programmed, once the continuity between high and low GB connections is made, the G6100 Plus unit waits the 2sec programmed start time then applies current to the DUT.
  • Page 107 Menu. 2.7.1 Offset The Guardian 6100 Plus provides automatic offset for lead or fixture effects. During the offset process a correction is made (subtracted out) as the result of lead leakage current and stored in instrument memory to be applied to ongoing measurements. For maximum measurement accuracy it is recommended that offset be performed after power-up, any time the test parameters are changed and any time the test leads or fixture are changed.
