4.4.2 Analogue Output – Scaling with DAC.0 and DAC.1
With the DAC.0 and DAC.1 values the output can be rapidly scaled to Your efforts.
Keep in mind not to connect low-resistive loads to the output, otherwise the output value will be wrong and battery life is
decreased. Loads above ca 10kOhm are uncritical.
If the display exceeds the value set by DAC.1, then the device will apply 1V to the output
If the display falls below the value set by DAC.0, then the device will apply 0V to the output
In case of an error (Err.1, Err.2, no sensor, etc.) the device will apply slightly above 1V to the output.

return to manufacturer for repair
6 Calibration Services
Calibration certificates can be issued by the factory. For this the device has to be sent to the manufacturer. Just the
manufacturer can check the factory settings and correct them if necessary.
