Details
Enables the user to alter the PV damping value in seconds
Enables the PV (pH, ORP, pION or Ion Conc) low and high
range values to be set for the range.
Enables the configuration changed flag to be changed.
A value in the range of 3.8 to 21.5 can be written to fix the
output of the device.
A value of 0.0 should be written to fixed Output Value to
exit the device from fixed output mode.
Performs self-test function on the device.
Device can be reset.
PV unit (pH, mV, ppb, ppm, %, ug/l or mg/l)
ug/l = micro-grams/liter
mg/l = milli-grams/liter
Enables user to trim the lower endpoint (for
example,~4.0mA) of the device's output.
Enables user to trim the upper endpoint (for example,
~20.0 mA) of the device's output.
User can alter the PV output linearity (used if a
function-generator is needed for output adjustment)
