Calibrate
This menu, in conjunction with an ammeter, is used to calibrate the mA output.
Press
ENTER
to start the calibration.
Fixed 4 mA Out
The controller will output 4.00 mA. Adjust the chart recorder or data logger per its
instruction so that the process value displayed is what is expected for a 4.00 mA
input.
Fixed 20 mA Out
As above, except that the controller will output 20.00 mA.
The design of the 4-20 mA output is such that it should never need calibration. If
the mA signal is not what it should be, call the factory for service.

Access Code Menu
This menu determines whether the access code feature of the controller is enabled or
disabled and allows you to customize the access code. The access code controls
whether or not you are allowed to change the parameters in the controller. With the
access code disabled, any user may change any parameter. With the access code
enabled, any user can view any parameter, but cannot change them.
Once an attempt is made to change a parameter, the display will prompt the user to
enter the access code. If the correct code is entered, the parameter can be changed.
(If the cursor is blinking, a change will be allowed; if the number or words are not
blinking, they can't be changed). Once the correct access code has been entered, it
will remain valid until there is a period of 5 minutes without a key being pressed.
