Lake Shore Model 620/622/623/647 Magnet Power Supply User’s Manual
Remote Operation 4-12
OVP? Overvoltage (Quench) Protection Circuit Status Query
Input: OVP?
Returned: 0 if the circuit is inactive, or 1 if it is active.
Remarks: One character plus up to two terminators are returned.
RES? Resolution Query
Input: RES?
Returned: 0 for low resolution or 1 for high resolution. (This command maintains compatibility with older
MPS versions. Remote interface operation does not change since the remote resolution is
already to the 0.0001 place.)
Remarks: Returns two characters plus up to two terminators.
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 ±5.000 V (620), 0 and ±30.000 V (622/623),
or 0 and ±32.000 V (647).
Remarks: Returns nine characters plus up to two terminators.
VSET (V) Enter Compliance Voltage
Input: VSET [voltage] or V [voltage] where [voltage]: = a value from 0 and ±5.000 V (620),
0 and ±30.000 V (622/623), or 0 and ±32.000 V (647).
Remarks: The initial condition is +00.0000 V. The voltage setting is always forced to a “+.” Control Bus
inputs 4 places, display rounds to 0.01 or 0.001 place.
VSET? Compliance Voltage Setting Query
Input: VSET?
Returned: A number between 0 and ±5.000 V (620), 0 and ±30.000 V (622/623),
or 0 and ±32.000 V (647).
Remarks: Returns nine characters plus up to two terminators.
