Table 2-5: IEEE and RS-232 Commands (Continued)
Command
Function Parameter(s)
SYSTem:
TIME Set the time to hours, minutes hh:mm
DATE Set the date to month, day, year mm/dd/yyyy
LOCKout state Set the front panel lockout off or on 0 (Off) 1 (On)
ELAPsed? Query the elapsed time the machine has run
DCALibration? Query the calibration date
MEASure:
RESistance Measure the resistance value
CURRent Measure the current value
FETCh?
Fetches the most recent measurement value (with pass/fail if limit selected) for the
selected parameter, resistance or current. The character sequence is as follows,
terminated with a line feed: N.NNNNE+NNN (2 spaces) PASS. The plus (+) sign will
be negative (-) when the parameter is selected as current. Pass can also be Fail or neither
if no limit is entered.
IDN?
Returns instrument identification "QuadTech,1865,0,software version"
START
Initiates a measurement in Auto mode, in Manual mode it initiates charge, if sent again it
takes one measurement, each time sent thereafter one additional measurement is taken.
STOP
Stops a measurement in process in Auto mode, in Manual mode it exits the measurement
loop to discharge , if sent again it exits discharge.
CALibrate:
DATA? Returns the calibration data to the user (21 values)*
ZERO Instrument zero
* Refer to Note on next page for 21 values
NOTE:
When a “Bad Zero Calibration” message is returned, query the IEEE for an error using
the ESR for a decimal value of 16 for an execution error. Looking at the execution error
prevents an automation program from hanging while waiting for the instrument to make a
measurement and return a value.
