Section 5.15 - Function 9 - Calibration
The DP600A and DP612A are factory calibrated and do not require additional user
calibration under most circumstances. For 2 wire RTDs Function 9 may be used to
calibrate out lead wire resistance. This calibration is done independently for each
channel.
To perform lead wire calibration short the RTD that needs to be calibrated at the
end of the lead wire. Next select the Zone to be calibrated in the primary Display
using the increment button. Press the select button to perform the calibration. While
the unit is calibrating the Zone flashes to indicate it is busy. Once the calibration
is complete the Zone will stop flashing. If the lead wire resistance is more than 10
ohms the unit will display “FAIL” and the calibration value will be set to 0.
