M?
Service Request Enable Register query
Function: This query informs the user how the Service Request Enable
Register is configured. See the Mn command for a descrip-
tion of the Service Request Enable Register.
At power-up the default is M0, which means that the <SRQ>
will not be asserted regardless of any bits that are set in the
Status Byte Register.
See Appendix A for a detailed description of the Status
Reporting System.
Syntax: M? or m?
Parameter: none
Returns: 000 - 255
Example: Send: M?
Resp: 000 An <SRQ> will not be asserted.
Send: M?
Resp: 016 Only the MAV bit will assert an <SRQ>
Send: M?
Resp: 255 Any bit in the Status Byte Register will assert
an <SRQ>.

Auto-Calibration
Function: This command is used to calibrate the 1830-C for future
measurements. The auto-calibration process involves mea-
suring amplifier offset voltages which arise from aging and
temperature effects. These offsets are then appropriately
corrected for during normal operation. The 1830-C will
automatically disconnect the input signal from the amplifier
during the auto-calibration mode. To achieve stable readings
at the specified accuracy, auto-calibration should be ex-
ecuted after a minimum 60 minute warm-up period.
The status byte register can be used to monitor the comple-
tion of the auto-calibration process, because during the auto-
calibration the BUSY bit remains high.
Syntax: O or o
Parameter: None
