ARM[:STARt]:LEVel[<chan>]:POSitive <voltage>

Example Setup to arm only when the signal on channel 2 falls through -0.48 volts.

ARM:SOUR1 INT2	Set arming source 1 to arm when the
	specified level is met on channel 2
ARM:SLOP1 NEG	The signal must fall through the level set by
	ARM:LEVel2:NEG for arming to occur
ARM:LEV2:NEG -0.48	Arm when the signal passes through the
	-.48V level

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

ARM[:STARt]:LEVel[<chan>]:POSitive <voltage> selects the input voltage level which will arm a measurement cycle. The ARM:LEVel:POSitive 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 POSitive 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 NEGative.

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.
