At the second mA adjustment screen, the MX 9000 outputs the value that should equal 20mA output.
Change the mA value on the screen to match the value shown on the user’s readout equipment and
press
ENTER when done.
At the next screen, the MX 9000 outputs the corrected 4mA value for loop 1. At the last screen the MX
9000 outputs the corrected 20mA value for loop 1. If either measured output is still not close enough to
the required value, enter the calibration routine again for loop 1. When done, press
EXIT until back at
STATUS screen.
Loop 2 is calibrated in an identical manner – just select “Calibrate Output Loop 2” in the IO Function
screen. NOTE: Loop 2 is only available if option boards 1 or 2 are present.
I/O Manual Adjustment
Whether for troubleshooting purposes or to manually control external equipment, the MX 9000 allows
the user to enter an I/O routine in which the analog output, Limit outputs and Frequency outputs can be
controlled and the external Reset input can be monitored. A good use of this feature is to verify
communication between the MX 9000 outputs and the users’ readout equipment in a controlled fashion
before final system installation.

When entering the I/O programming mode from the STATUS and password screens, use the
UP or
DOWN button to change the I/O Function to ‘Test output’ as shown above and press ENTER . Next
choose which I/O to change and press YES .
Analog Output Adjustment
The user can manually control the mA output to any value between 2mA to 20mA in one of two ways.
Fine adjustment allows user to program a specific mA value to output. Coarse adjustment allows user to
increment or decrement the mA value in 1mA steps using the
UP and DOWN buttons. Use SELECT to
choose which control is desired. HINT: Coarse allows a quick way to step from 2 to 20 mA.
