Description
Set voltage source to +1000V
Voltage source +1000 V cal
Set voltage source to -1000 V
Voltage source -1000 V cal
Humidity input 0 V step
Humidity input 0.5 V step
Humidity input 1.0 V step
Re-locks the calibration paths. (A new CAL switch
press and CAL:PROT:INIT command are required
before any cal commands can be performed again.)
Saves the cal constants in NVRAM
Calibration date yyyy = year (1994-2093), mm = month
(1-12), dd =date (1-31)
Request calibration date
Calibration due date
Request calibration due date
Request CAL switch state (0 = unlocked, 1 = locked)
Acquire the calibration temperature.
These commands not protected by CAL switch
Perform offset voltage calibration
Perform bias current calibration
Request cal execution error status
Request voltage function cal errors
Request amps function cal errors
Request coulombs function cal errors
Request temperature function cal errors
Request factory calibration errors
Request option presence status
