[:STARt]:LEVel[<chan>]:NEGative <voltage>

ARM[:STARt]:LEVel[<chan>]:NEGative <voltage> selects the input voltage level which will arm a measurement cycle. The ARM:LEVel:NEGative setting is used only when either of the ARM:STARt:SOURce(s) is set to INTernal1 or INTernal2, and the corresponding ARM:STARt:SLOPe<n> setting is NEGative or EITHer. The value programmed is retained (but not used) when other sources are selected, or when the corresponding ARM:STARt:SLOPe<n > setting is POSitive.

The allowable levels depend on the measurement range as set by the

SENSe:VOLTage:RANGe command.

Comments Executable while initiated: No

Coupled Command: Yes. The command is coupled to the ARM[:STARt]:SLOPe, ARM[:STARt]:SOURce, and SENSe:VOLTage:RANGe commands. The level value is limited to the range limits.

When POSitive and NEGative voltage levels are specified, the levels must be separated by an amount defined by:

(50 mV / 1.0235V) * measurement range

This accounts for offset errors in the levels specified and enables the levels to be detected.
