Sets the resistance source function value for source 1. The command belongs to the SOURce[1] subsystem and is documented as the resistance function command.

Selects the source function for source 1.

Sets the source setpoint tolerance for source[1].

Sets the temperature source function. The command belongs to the SOURce[1] subsystem.

Sets the source voltage setpoint for the selected source. This command belongs to the SOURce[1] subsystem voltage function.

Selects the data format for transferring instrument readings over the bus. Only ASCII is allowed over the RS-232 interface, and the setting affects the output of READ?, FETCh?, and MEASure[:<function>]?, over GPIB.

Selects the data format used for transferring instrument readings over the bus. Only ASCII format is allowed over the RS-232 interface; the command affects READ?, FETCh?, and MEASure[:<function>]? output over GPIB.

Specifies which data elements are included in the data string returned by following :FETCh?, :READ?, and :MEASure[:<function>]? queries. The elements are separated by commas and may include one to all listed items.

Specifies which data elements are included in the data string returned by subsequent :FETCh?, :READ?, and :MEASure[:<function>]? queries. The elements are separated by commas and can include one or more of the listed measurement and status items.

Sets the response format for all SOUR2:TTL queries. It works similarly to formats set by the FORM:SREG command.

Controls the response format for all SOUR2:TTL queries, similar to formats set by the FORM:SREG command. Set the format with one of four keywords.

Specifies the binary byte order used for IEEE-754 binary formats. Normal order sends bytes 1-4 in sequence; SWAPped reverses them. ASCII data is always sent in normal byte order, and the #0 header is not affected.

Queries the current byte order used for IEEE-754 binary data formats. The ASCII data format always uses normal byte order, and the #0 header is not affected by this command.

Sets the response message format used when reading status registers. The selected format controls how queried status register bit patterns are returned.

Sets the response message format used when reading status registers. The selected format affects the values returned by status register query commands.

Aborts the source/measure operation, returns the instrument to the idle state, and turns the output off.

Initiates the control-measure cycle by taking the Model 2510 out of idle. The :READ? and :MEASure? commands also perform an initiation.

Starts the selected measurement or operation sequence. The command is listed in the SCPI commands section; no syntax, parameters, or response details are shown in this page slice.

Sets the units for the temperature function. The selected units affect both temperature command parameter units and temperature reading units.

Queries the temperature units used by the temperature function. The setting affects both temperature command parameter units and reading temperature units.

Returns the next error from the instrument’s error queue. The page slice uses it in examples of common SCPI errors and notes that you must read the response before sending another query.

:SYST:ERR?
:SYST :ERR?

Sends the device into local mode as part of IEEE-488/SCPI remote-local transition behavior. The manual notes its coupling to the local/remote transition described elsewhere.

Puts the instrument in remote mode. It is listed with GTL as a coupled command affecting local/remote transition.

Sets the temperature loop gain constant (P).

PRINT #1, "OUTPUT 15;:SOUR:TEMP:LCON 10" ' Gain (P) constant = 10.

Sets the lower temperature protection limit for the selected temperature function. The example shows it used with a numeric value in degrees.

PRINT #1, "OUTPUT 15;:SOUR:TEMP:PROT:LOW 10" ' Lower limit = 10 deg.

Sets the upper temperature protection limit. The example program uses it to limit temperature to 90 degrees.

PRINT #1, "OUTPUT 15;:SOUR:TEMP:PROT 90" ' Upper temp. limit = 90 deg.

Queries the TEC current reading.

Queries the TEC DC resistance.

OUTPUT 15;:MEAS:RES?

Queries the TEC voltage reading.

PRINT #1, "OUTPUT 15;:MEAS:VOLT?" ' Query TEC voltage.

Turns the output on or off.

PRINT #1, "OUTPUT 15;:OUTP ON"
PRINT #1, "OUTPUT 15;:OUTP OFF"

Returns the present reading from the instrument.

Aborts the trigger subsystem's source/measure cycle.

Initiates the trigger subsystem's control/measure cycle. This command is listed under the trigger subsystem commands.
