Operation manualOxyScan Transmitter waterproofThe OxyScan Transmitter is a measuring amplifier for UMS oxygen sensorsto measure dissolved oxygen in liquids.The liquid temperature and the atmospheric pressure are measuredsimultaneously and automatically compensated.The measured value is output as a current signal via a 4-20 mA currentloop. There is no need for additional electric power.Handling of the O2 sensor (electrochemical)Always store the sensor in its calibration chamber when not in use!The membrane (thin, be careful) atthe sensor tip can be cleaned carefullywith a moistened cotton ball.A constantly increasing display value indicates a damaged membrane.In this case, the sensor must be replaced or regenerated.The sensor consumes minimal amounts of O2 during the measurement.Therefore it requires a little liquid flow to achieve stable readings.For measurements in standing liquids, the sensor should be movedslightly.For permanent installation in piping systems:The liquid flow rate should be at least 2 cm / sec.1
