Multi-Point Scaling
When Multi-Point Scaling is enabled (
 =  in Configuration Mode), up to 9
breakpoints can be set to linearize the input signal. This only applies to mA, mV or Voltage
input types.
For each breakpoint the input scale value (n) is entered in % of input span, followed by
the value to be shown (n
) in display units. Each breakpoint’s input scale value must be
higher than the previous value, but the display values can be either higher or lower. Any
scale value set to 100% becomes the last in the series.
Tare Feature
When Tare is enabled ( =  in Configuration Mode), it can be used to set the
displayed value to zero automatically, by making the PV Offset parameter equal, but
opposite to, the current process variable value.
Tare can be initiated via the Digital Input (if fitted), with a communications command via the
RS485 module (if fitted) or by using the following key press sequence:
Press until the process variable is displayed.
Hold down and together for three seconds until the display shows 
Release both keys and press within 3 seconds to confirm the request.
Note:
The Tare request is aborted if this sequence is not followed exactly.
