“Analog Output Status” & “Configure Analog Output” Menus
The current process and output value for each
analog output for each channel is shown based upon
the current scaling setup. In addition the the type of
sensor that is assigned for that channel and hold
status is also displayed for each channel. On this
screen you can choice whether you wish to use ppm
or percent (%) saturation units for the analog output
of the dissolved oxygen sensors. The toggle allows
you to switch between these two units. Toggle is
only active when sensor type is dissolved oxygen.
To change the output type click on the “
Configure
Analog Outputs Channel
” which will load the screen
shown in the screenshot further below. You must
first choose the channel for which you wish make
any changes to the analog output before you can
select the output type.
From the “
Configure Analog Outputs Channel
”
screen you can choose the output type as either
voltage (0-10 VDC) or current (4-20mA).
Output# 4 is the Temperature Value from Sensor #1
Output# 5 is the Temperature Value from Sensor #2
Output# 6 is the Temperature Value from Sensor #3
When you click the “
Update Channel
” button you
will be prompted to confirm the change with yellow
dialog box. The change will take effect immediately
once you exit this dialog box.
After choosing the output type for the given channel
click “
Back
” to return to the “Analog Outputs
Status” screen and then click on the “
Scale Analog
Outputs
” and follow the instructions on following
