MRU Instruments OPTIMA 7 Biogas User manual

  • Hello! I've reviewed the user manual for the MRU AMPRO 2000, specifically the section on replacing the O2 sensor. This document details the steps for accessing, mounting, and preparing your analyzer for calibration after a sensor change. I'm familiar with steps like removing parts, specific sensor mounting instructions and the post installation waiting time before calibrating. Feel free to ask me any questions you have about this process.
  • How many rear screws need to be removed?
    What should i do with the connectors?
    How long must the O2 sensor be installed before calibrating the analyzer?

Remove the condensate separator
Remove the 4 rear screws
Take the housing apart
The sensors are under the sensor chamber.
Remove the sensor chamber from the sensors
The O2 sensor can be either A or B. Remove the old sensor and then check the
connectors (4) if they are clean – clean them if necessary with alcohol (or replace if
needed). Insert the new sensor.

O2 Sensor 2 – there is only one way the sensor can be mounted.
O2 Sensor 3 – pay attention to the + and – sign on the sensor and the sensor board.
O2 Sensor 4 – there is only one way the sensor can be mounted.
O2 Sensor 5 - there is only one way the sensor can be mounted.
Now you can reassemble the analyzer and calibrate the unit.
PLEASE NOTE!!!!
Before calibrating the analyzer the O2 sensor must at least be installed for
about 4 hours (best is over night!)
