Operation
Command Reference
Command | Description |
IRDAT <Ilo>,<Ihi> | Calculates and records the slope and offset for readback voltage using |
| IRLO and IRHI data. Set CMODE ON before using this command. See also |
| the calibration procedures in Section 4. |
| <Ilo> and <Ihi> are in <current> format. |
IRHI | The power supply outputs a current value to an external device connected |
| as part of the calibration procedure and records a current readback value |
| internally. These values are at the high end of the programmed current |
| range. Refer to the output value as IRHI and record it to use as input with |
| the IRDAT command. Set CMODE ON before using this command. See |
| also the calibration procedures in Section 4. |
IRLO | The power supply outputs a current value to an external device connected |
| as part of the calibration procedure and records a current readback value |
| internally. These values are at the low end of the programmed current |
| range. Refer to the output value as IRLO and record it to use as input with |
| the IRDAT command. Set CMODE ON before using this command. See |
| also the calibration procedures in Section 4. |
ISET <current> | Sets the power supply’s output current in amps (default) or in milliamps. |
| This programmed current is the actual output in CC mode or the current |
| limit in CV mode. |
| Range: 0 to model maximum output current (IMAX) |
| Initial value: 0 amps |
|
|
ISET? | Asks for the supply’s present output current setting. Does not apply to |
| current settings which are being held. See HOLD command. |
| Response: ISET <current> |
|
|
MASK <mnemonics> | Disables the supply's previously unmasked operating conditions from |
| setting bits in the fault and status registers. See “Accumulated Status, |
| Status, and Fault Registers” on page 46. Mnemonics are separated from |
| each other by commas and may be sent in any order. |
| Mnemonics: CV, CC, OV, OT, SD, FOLD, ERR, PON, REM, ACF, OPF, |
| SNSP |
| Note: UNMASK NONE = MASK ALL (Initial value) |
| MASK NONE = UNMASK ALL |
OUT <1/ON>,<0/OFF> | Enables or disables the supply’s voltage/current output. The supply will |
| continue to accept new commands while the output is disabled but these |
| will not be implemented until OUT ON or OUT 1 is received. OUT ON is the |
| default setting. When you start the supply in remote mode, the output is |
| enabled. |
| OUT OFF (or OUT 0) also sets the isolation signal on the rear panel J21 |
| connector, line 3. You can use the to trip external relays to isolate the power |
| supply from the load. |
| Initial value: OUT ON (or OUT 1) for output enabled |
OUT? | Asks for the present enabled/disabled status of the supply’s output |
| voltage/current. |
| Response: OUT 1 output enabled or |
| OUT 0 output disabled |
