ZEROC
ZEROD
‘Zeros’ the pressure sensor offset.
ZERODIFF1
ZERODIFF2
ZERODIFF3
‘Zeros’ the pressure sensor offset for the respective analog input.
NOTE 1
The analog input range is -1.5 to 11.6 volts. There is NO conversion of the returned number. The number returned (0
to 65535 decimal) will have an offset of 7500 added to the number (7500 = 0 volts) and a scale of 5000 for every 1
volt, for example:
NOTE 2
The only pump B commands accepted in continuous pumping mode or Modifier Addition Mode are: %B, FLOWB,
LIMITSB, PRESSB, REFILLB, REFILLB=, STATUSB, VOLB.
