Changing The Polarity Of An Output Device - Thermo Scientific APEX 100 User Manual

5) Navigate to the warning icon currently assigned to Output 4 and press the Go
button. The select-options screen reappears. Highlight the reject-1 icon and press
the Go button. The detector closes the menu and your reject device is now assigned
to Output 4, as shown by the updated output screen below.

6) Finally—and do not forget this key step!—disconnect your reject device from
Output 1 on the detector's wiring board and reconnect it to Output 4, being careful
not to switch the original polarity. (If you do, you can always use this menu to
change the polarity to minus.) For more details about the detector's output-wiring
board, see page 290.

Changing the Polarity of an Output Device

You use this function to tell the detector to send a positive (+) or negative (–) voltage
signal to a particular output (Output 1–6). The screen below currently shows the
following.
•
Your reject device is currently assigned to Output 1. (For your application to
work, your reject device must also be physically connected to Output 1 on the
detector's wiring board.)
• To trigger the reject device, the detector sends a positive (+) voltage signal to
the reject device.
