6.11.3 %-Error function
WARNING!
Observe the connection parameters prior to making a connection to the
instrument.
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 span. The %-Error mode
uses all three screens and has a special menu structure. It displays pressure, mA and
%-error simultaneously.
Example:
Suppose a pressure transmitter under test has a full scale range of 0 ... 20 bar and gives
a corresponding 4 ... 20 mA output signal. The user can programme in a 0 ... 20 bar
