Example:
A pressure transmitter under test is 30 psi (2 Bar) Full-
Scale and outputs a corresponding 4 mA to 20 mA signal.
Program a 0 psi to 30 psi pressure span into the Product
and the Product calculates and shows the deviation or
%Error from the expected 4 mA to 20 mA output. This
eliminates the need for manual calculations and helps
when it is difficult to set an exact pressure with an
external pump.
To use the %ERROR function:
1. Push to access the menus.
2. Push to step through the menu until %ERROR is
shown on the menu bar.
3. Push to open the %ERROR screen.
4. Push to scroll through the port choices (P1, P2,
EXT).
5. If necessary, push to configure the %ERROR
option and turn Loop Power on or off.
6. When finished, push .
7. Use the arrow keys to set the 100 % point of the
desired pressure range, select DONE SET when
finished.
8. Use the arrow keys to set 0 % point and select
DONE SET when finished and the % ERROR mode
will be ready to use.
Note
The 0 % and 100 % point will be saved in non-
volatile memory until they are changed again by
the user for the internal sensors, and external
pressure modules. When an external module is
used, the 0 % and 100 % are set to low and full
scale of the module until the user changes it, or
if it was previously saved.
