Command
SYSTem:

LOCKout state
ELAPsed?
DCALibration?
MEASure:
RESistance
CURRent
FETCh?
Fetches the most recent measurement value (with pass/fail if limit selected) for the
selected parameter, resistance or current.
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?
ZERO
* Refer to Note on next page for 21 values
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
Operation
Function
Set the time to hours, minutes
Set the date to month, day, year

Query the elapsed time the machine has run
Query the calibration date
Measure the resistance value
Measure the current value
Returns the calibration data to the user (21 values)*
Instrument zero
