“Hold Channel Output” Menu
Before performing any cleaning or re-calibration
place the sensor for the channel in question on hold
first. The default settings where no channels are on
hold is shown to the right.
Select the channel of the sensor to be removed from
service for cleaning and/or re-calibration.
Place the selected channel on hold before removing
from service for cleaning and/or recalibration.
After completing the cleaning and/or recalibration
connect the sensor back into service and then take
that channel off from hold.
In the example should to the right the sensor for
channel #3 is currently out of service.
IMPORTANT NOTE ABOUT ANALOG OUTPUTS FOR TEMPERATURE:
When channel # 1 is taken out of service, then channel # 4 output which is temperature output from channel # 1 will also
automatically be placed on hold. Similarly when channel # 2 is taken out of service, then channel # 5 output which is
temperature output from channel # 2 will also automatically be placed on hold. Lastly, when channel # 3 is taken out of
service, then channel # 6 output which is temperature output from channel # 3 will also automatically be placed on hold.
When channel # 1 is return back to service channel then temperature output # 4 will also be take from hold. Similarly
temperature output # 5 will be restored when sensor # 2 is removed from hold and finally temperature output # 6 will be
restored when sensor # 3 is removed from hold. These temperature outputs are handled automatically since the
temperature value that serves as the basis for the temperature outputs requires the sensor to be active & online.
