I/O Manual Adjustment
Whether for troubleshooting purposes or to manually control external equipment, the RT-30EX 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 RT-30EX outputs and the users’ readout equipment in a controlled fashion
before final system installation.
When entering the I/O programming mode from the STATUS screen, use the UP or DN button to change
the I/O Function to ‘Test output’ as shown in Figure 40 above and press ENT . Next choose which I/O to
change.
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 DN buttons.
