Page 5: Introduction
Pico-O2 | Manual INTRODUCTION Pico-O2 (item no. PICO-O2) is a fiber-optic OEM meter for read-out of optical oxygen sensors from PyroScience. The measures oxygen gas (e.g. %O2) or dissolved Pico-O2 oxygen in liquids (DO) and the firmware provides internal calculation of all major oxygen units taking into account adjustable values of temperature, pressure, humidity, and salinity. -
Page 6: Overview
OPROB3 is a fiber based optical sensor. The fiber has a length of 1 meter and is connected to the optical port of the Pico-O2. The dipping probe OPDIP20 is made out of stainless steel and has a length of 20 mm. Both probes have a diameter of 3 mm and are applicable in gas and liquid phase. -

Page 18: Communication Protocol
Pico-O2 | Manual Communication Protocol 5.4.1 General Definitions A command always starts with a specific command header (e.g. MEA, #VERS, #LOGO) optionally followed by several input parameters. Input parameters are given as human readable decimal numbers, separated by spaces from each other. Each command must be terminated by a carriage return. - Page 19 Pico-O2 | Manual Bit 5 (add 32): case temperature (temperature within the module) Example: S = 1 + 2 + 4 + 8 + 32 = 47 means, that the command will trigger the following measurements: optical channel (oxygen), sample temperature, case temperature, ambient air pressure, and relative humidity within the module housing.
- Page 20 Pico-O2 | Manual This command is the essential command for triggering measurements. If the input parameter S is requesting several sensor types to be measured, the optical oxygen measurement ("optical channel") is always performed as the last measurement. This ensures that for enabled automatic temperature compensation the sample temperature measurement (typ.

This read command returns N (N=1…64) consecutive values Y from the user memory starting at the user memory address R (R=0…63). - Page 26 Pico-O2 | Manual Note: Warnings and errors directly related to the sensor measurements (e.g. a broken Pt100 temperature sensor, or a "worn out" optical oxygen sensor) will not result in such an #ERRO response. Instead, such warning and errors are given in the output parameter of the MEA command (see above).
