Accuracy specifications shown are valid at temperatures within ±5C of the calibration temperature. Outside of this range, add 10% of the specification per C.

Decrease maximum ACW, DCW, and IR voltages by 2.5%/1000ft above 5000ft ASL altitude.

All accuracy specifications are valid at the V7X terminals, and as such, do not include any effects due to user wiring resistances, leakages or coupling, or other user-generated leakages or interference.

Resolutions shown are for displayed measurements, limits, and settings. Internally all measurements typically have 10x better resolution, and all limits and settings are implemented with the same resolution as entered by the user. Via an interface, all measurements are reported with 5 digit resolution.

Generally, user settings can be defined with up to 4 digit resolution and a selection of units (e.g. µA or mA) from the front panel; or with up to 6 digit resolution from an interface.

Unless otherwise specified, user terminated dwell/test periods can extend for up to 2 days.

Not all test types are available in all models of V7X.
