Save calibration and set the adjustment dates
Use the following commands to save and lock calibration adjustments. These steps will take seconds
to complete.
cal.save()
cal.lock()
Calibration is temporary until you send the cal.save() command. Also, calibration data is not
saved if calibration is locked, if invalid data exists.
This completes the remote calibration adjustment procedure.
Setting time, adjustment, and verification dates
The DMM6500 calibration adjustment date variable is set automatically to the present system time
when the cal.save() command is executed. However, you can also use Test Script Processor
(TSP
®
) commands to set the time, verification date, and adjustment date.
To set the DMM6500 time, adjust date, and verify date using TSP commands:
-- Unlock calibration (if not already unlocked).
cal.unlock("KI000CAL")
-- Set the time (year, month, date, hour, minutes, seconds).
localnode.settime(2018, 1, 9, 10, 4, 38)
-- Set the adjustment and verification dates.
cal.adjust.date = os.time({year = 2018, month = 1, day = 9})
cal.verify.date = os.time({year = 2018, month = 1, day = 9})
The cal.verify.date command is used to record the date of the last verification that was done
independently of DMM6500 adjustment. Typically, this date is set at the completion of a performance
verification procedure.
Calibration must be unlocked to change the adjustment and verification dates, but changing these
dates does not require using the cal.save() command and does not affect the cal.count
command.
