Voltage/current measuring calibration:
The caibration aism to correct measurement errors (voltage and current) . It must be performed with class 1.25 at least. If this recommendation is
not followed, the measures will be false. This operation must be done by a qualified person, following the procedure on screen. It requires a master
code '0000', which can be modified and the following load settings :
0.25 Ω - 625 W / 0.2Ω - 2kW / 0.1Ω - 4kW.

The machine indicates the calibration class for the measurement tools which are required to
calibrate the machine.
At this step, a password is required : 0000, it is preferable to modify it for safety purposes.
The first voltage test is performed at 50A with a 0.025Ω resistive load, thus a total resistive
power of at least 625W.
The left knob sets the actual current consumed by the machine. It must be adjusted at 50A
according to the class 1.25 measurement. The right knob can set the voltage measured by the
machine, which must be as close as possible to the class 1.25 measurement.
The second voltage test is performed at 100A with a 0.2Ω resistive load (2kW).
The current should be at 100A and the voltage as it's measured on the anmeter.
