Attributes:
| Name | Description |
|---|---|
| CurrentScalar: DevDouble | Storage ring current in mA |
| LifetimeScalar: DevDouble | Storage ring current lifetime in seconds |
| InjectionRateScalar: DevDouble | Compute the injection rate (delta I / delta t). Required at least 10 values in history buffer It is possible to read this attribute only when the device has detected one injection (MOVING state) |
| DMMVoltageScalar: DevDouble | The last voltage value read from the digital DMM |
| FitSizeScalar: DevLong | The maximum number of samples in history buffer on which to apply a lifetime fit computation. |
| CurrentDecreaseDeltaScalar: DevDouble | The maximum delta current between the first point and the last point in current history which will be taken into account in lifetime fit calculation |
| CurrentIncreaseDeltaScalar: DevDouble | The minimum current increase which is used to decide that an injection is in progress |
| NewGainScalar: DevDouble | New value for Gain resulting from a calibration. The gain is used in current value computation. Will be used and memorized after a StoreNewGainAndOffset command Set to 0 until a calibartion is performed |
| NewOffsetScalar: DevDouble | New value for Offset resulting from a calibration. The offset is used in current value computation. Will be used and memorized after a StoreNewGainAndOffset command Set to 0 until a calibration is performed |
| GainScalar: DevDouble | The linear coefficient used in current computation Current = (Measure + Offset ) * Gain |
| OffsetScalar: DevDouble | The offset used in current computation Current = (Measure + Offset) * Gain |
| LifetimeIntegrationTimeScalar: DevDouble | Delta time in history buffer taken into account for lifetime fit |
| RawCurrentScalar: DevDouble | Storage ring current in mA not corrected for negative value (needed by expert) |
Commands:
| Name | Description |
|---|---|
| StateInput: DevVoid Output: State State Code |
This command gets the device state (stored in its <i>device_state</i> data member) and returns it to the caller. |
| StatusInput: DevVoid Output: ConstDevString Status description |
This command gets the device status (stored in its <i>device_status</i> data member) and returns it to the caller. |
| DoCalibrationInput: DevVoid Output: DevVoid |
Start a calibration process |
| StoreNewGainAndOffsetInput: DevVoid Output: DevVoid |
Store the new computed gain and offset in the database and use them in current computation |
Pipes:
Properties:
| Name | Description |
|---|---|
| DMMDeviceNameDevString | The device name of the digital multimeter |
| GainDevDouble | PCT gain |
| OffsetDevDouble | PCT offset |
| CalibrationResistorDevShort | Value in ohm of the resistor used for the calibration. |
| HasCalibrationHardwareDevBoolean | Set to true if the required hardware to calibrate the PCT is available inside the DMM. |
| CalibrationTypeDevString | Defines which kind of calibration has to be applied. |
