Availability: Always
Command Syntax: ERROR?
Response: <Error Mode>
Response Example: 0 Response Range: 0 or 1
Description: The ERROR? query returns the selected error reporting mode.

IMAG? Query magnet current (or magnetic field strength)
Availability: Always
Command Syntax: IMAG?
Response: <Magnet Current> <Units>
Response Example: 87.9350 A
Description: The IMAG? query returns the magnet current (or magnetic field strength) in the
present units. If the persistent switch heater is ON, the magnet current returned will be the same as
the power supply output current. If the persistent switch heater is off, the magnet current will be the
value of the power supply output current when the persistent switch heater was last turned off. The
magnet current will be set to zero if the power supply detects a quench. If in SHIM mode, the
IMAG? query reports the present current of the shim selected by the SHIM command in Amps. If
the optional Shim ID is provided while in shim mode, the present current of the specified shim will
be reported.

IMAG Sets the magnet current (or magnetic field strength).
Availability: Remote Mode
Command Syntax: IMAG [value]
IMAG <shim_id> <value> (shim mode only)
Example: IMAG 47.1123
IMAG X2 -13.4571 (shim mode only)
Default Parameter: 0.0 Parameter Range: ±Maximum Magnet Current
Description: The IMAG command sets the magnet current shown on the display. The supply must
be in standby or a command error will be returned. The value must be supplied in the selected units
- amperes or field (kG). If Shim Mode is enabled, the persistent mode current displayed for the
named shim is set if the shim parameter is provided.
