6.5.2 Atomic Calibration Commands
The atomic calibration commands provide individual calibration of voltage, current, temperature, watts
and a sequence of these results in providing full calibration for the unit.
6.5.2.1 CLV Command
An example of an atomic calibration command would be to calibrate voltage with the CLV command. The
CLV command calibrates voltage to the target value and tolerance and saves the coefficients to flash.
The CLV command example is given below:
>CLV
The response is:
VCal OK:
>
6.5.2.2 CLI Command
The user can then calibrate the current using the CLI1 command. The CLI1 command calibrates the
current to the target value and tolerance and saves the coefficients to flash. The CLI1 command example
is given below:
>CLI1
The response is:
ICal 0 OK:
>
6.5.2.3 CLP Command
The user can calibrate for phase added by a current transformer by using the CLP command. The CLP
command calibrates the phase to the target value and tolerance and saves the coefficient to flash. An
example of the procedure is given below.
Apply a controlled precision voltage and current signal at a set phase angle.
1. Enter target phase angle at )C3.
2. Enter phase tolerance at )BF
3. Enter phase calibration command.
>CLP
The response is
>PCal 1 OK:
