displays the current channel mV
Choose Channel (CH1…4)
When a Channel is selected and the
Optimize Gain key
is entered, the
Messenger will try to set the Gain (Increase or decrease) to adjust the output
level of the amplifier to 2000 mV (with range set at 100%) or higher if the 100% is
higher, this relates to the A/D input of 2500 mV (80 to 120%).
Choose
Restore Default Settings
to restore the %Range to the default value i.e.
100.
The TRIMPOTS of the Front End Amplifier can be selected manually using
Optimize Channel Manual.
Optimize Channel Signal Manual
This shows the TRIMPOT settings on the front end Amplifier Range 0 to 100.
Choose
Channel (1…4)
and Tap/Click on "+" or "-" in order to increment or
decrement the TRIMPOT Settings.
Auto Zero Dark Current
Choose
Auto Zero Frequency in Hours
text box to specify the Time Interval
(Hours) at which the Dark current should be made zero.
Store Channel Reference
Using this option you can store a reading from a channel, which allows us to
store an initial reference reading for the channel.
For Example:
When doing a color measurement with a single channel (detector) the equation
for sensor may look like the following:
LOG REF CH1 – LOG CH1. Where LOG REF CH1 is a constant as it relates to
the initial energy level with clear water in the cell.
