Remote Operation 4-13
RI?: Remote Inhibit Status Query
Input: RI?
Returned: 0 if the remote inhibit is inactive, or 1 if it is active.
Remarks: One character plus up to two terminators are returned.
VOUT? (V?): Output Voltage Query
Input: VOUT? or V?
Returned: A number between 0 and ±32.0000 V.
Remarks: Returns nine characters plus up to two terminators.
VMAX: Programs an upper (soft) voltage limit that the unit will accept.
Input: VMAX[voltage] where [voltage] = 0 to +32.0000 V.
Remarks: Normal resolution truncates the value to 0.01 place. High resolution truncates the value to the
0.001 place. The initial condition is +000.0000 V. The voltage limit is always forced to a plus.
VMAX?: Voltage Limit Query.
Input: VMAX?
Returned: A value between 0 and +32.0000 V.
Remarks: Returns a nine character value with up to two terminators.
VSET (V): Programs the output voltage in the voltage mode.
Input: VSET[voltage] or V[voltage] where [voltage] = 0 to +32.0000 V.
Remarks: Normal resolution truncates the value to 0.01 place. High resolution truncates the value to the
0.001 place. The initial condition is +00.0000 V. The voltage setting is always forced to a “+.”
Setting is limited by VMAX. Control Bus inputs 4 places, display rounds to 0.01 or 0.001 place.
VSET?: Output Voltage Setting Query.
Input: VSET?
Returned: A value between 0 and +32.0000 V.
Remarks: Returns a nine character value with up to two terminators.
