%-Error Function

The Product has 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 shows pressure, mA and %-Error
simultaneously. See Figure 28.

Example:
If a pressure transmitter under test has a full-scale range of 2 bar and gives a 4 ... 20 mA
output signal, you can program in a 0 ... 2 bar pressure span into the Product. The Product
will then calculate and show the deviation or %-Error value from the 4 ... 20 mA output.
This makes manual calculations unnecessary.
To use the "%-ERROR" function:
1. Once the Product is turned on, push  to start the "MORE" menu option. Then Push
2. Push  to select the "CONFIG" option.
