2.3.1.5. Minimum mA limit
Prevents the mA output from dropping below this minimum level for a
measurement value. This does not restrict the Failsafe or manual settings..
Values
2.3.1.6. Maximum mA limit
Prevents the mA output from rising above this maximum level for a
measurement value. This does not restrict the Failsafe or manual settings.
Values
2.3.1.7. 4 mA Output Trim
Calibrates the 4 mA output. The mA output of the device is pre-calibrated;
however, 4 mA Output Trim can be used to trim remote displays or inputs.
