It does not affect the calibration readings as the inputs to the meter are feeding differential amplifiers; ie the circuit reads the voltage between the two cell connections, not the voltage above 0V.
The cell meter leads will only read up to a maximum voltage of about 4.8V although higher voltages (up to 20V) will not cause any damage, but the meter cannot read them.
thanks , Wayne , that i can say i understand the explanation for 100% i have to say no , i am not an elecrial engineer , only i try to think logical
when i see 3 dean connectors in the circuit .
and the abbreviation CCT what does that mean ?
