Optimize Channel  Auto

The Messenger Device is provided with a  Multi Stage Amplification. The Primary stage of Amplification is done with help of Front End Amplifiers and  Secondary stage of Amplification is done with in the Analog to digital converter (ADC) that has an Internal amplifier.

The Front End Amplifiers setting can be done using  Optimize Channel Auto.

Example 1:
Adaptation of an absorption sensor to Signal in 1:

Example 2:
Adaptation of an scatter light turbidimeter.

The raw signal level (mV) should normally be in a range between 1200 and 2400 mV. (2500mV out of range). In such a case if the signal level is out of this tolerance try “Optimize gain manual” first.

In case even after the manual gain optimization one or more signals are out of tolerance, then there is every possibility that you need to change the gain by making using of jumpers on the hardware.

Please see the manual for details or contact Metrisa.

In case of very low Signals (e,g. Scatter light) measuring at a very low range the signals may even need max. Amplification under the tolerance level.

%Range is related to the set point i.e. 100% which is 2000mv and 120% is 2500 mv which is the range of the ADC Converter 

Raw mv 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.

ADC-GAIN Manual

This is a secondary stage of Amplification setting on the ADC chip where we have a FRONT end Amplification setting using the electronic trim pots which can be adjusted using 
Optimize Channel Auto 
or  
Optimize Channel Manual.

ADC gain setting allows a second stage of amplification when we are looking at very low signals and we need to amplify further beyond the front end range adjustment allowed.

This of course will cause a higher offset voltage and may reduce the range of the detection because of this offset potential that is due to the multi-stage amplification and the initial offset potential of the front-end op-amps.

The settings are defaulted to 1 but may be adjusted to 2,4,8,32,64,128

Choose Channel (1..4)  and Tap/Click on the "+" or "-"  in order to increment or decrement the gain setting.

Introduction

The multifunctional transmitter Model Messenger can be used with all sensors of the MoniTurb / MoniSpec series. The sensors of the MoniTurb series use the principles of forward and/or side scattered light for the detection of turbidity.

The sensors of the MoniSpec series (single channel - or dual wavelength - absorption) detect solid (or alternate colour) concentrations. Depending on the sensor type, the absorption measurements can be done in the UV, VIS or NIR range.

The Messenger even allows for simultaneous use of multiple sensors. Hereby you can use up to four sensors (single channel absorption). The measurement results can be linked together using almost any mathematical equation. This allows for easy implementation of dosage systems (difference measurement).

The programming / calibration of the system can be done via a PC or a handheld computer, using the menu-based software. The integrated data logger / paperless recorder simplifies the evaluation and archiving of measurement results.
