4.6.4 %-Error function
The calibrator features a special function which can calculate the
error in the pressure value from the mA value as a percentage of the
4 ... 20 mA loop span. The %-Error mode uses all three screens and
has a special menu structure. It displays pressure, mA and %-Error
simultaneously.
