Chapter 4. Initial setup and programming
4.6.1.3 Calibrate the output
4.6.1.4 Setting error handling
Use the [

] or [

] key to select a specific digit, then use the [

]
or [

] key to change that digit as required. After all digits are
correct, press [√] to save. Then, press [x] to return to the
previous screen. Repeat these steps to set the full value setting,
and press [x] to return to the analog output A menu.
Use the calibrate menu to trim the analog output. In the analog
output menu, select calibrate and press [√]. A screen similar to
the following opens.
Select either 4 mA to trim the 4 mA level, 20 mA to trim the 20
mA level, or percentage of scale to test the output linearity.
Select the desired option and press [√]. A screen similar to the
following opens.
Read the analog output with a digital multimeter, and enter
that value. Use the [


The following screen opens.
During an error condition, selecting low forces the
analog output to 3.6 mA or below, while selecting high
