3600 Analyzer for O Measurement—Operator’s Manual 1.3.1 Program Flow Charts The following flow chart depicts the menus you encounter when the instrument is first turned on, and an overview of the menu choices. The Measure menu is described further in section 1.3.2. The Calibration menus depicted below are described further in section 1.3.3.
3600 Analyzer for O Measurement—Operator’s Manual 1.3.2 Oxygen Measurement Typical 3600 instruments are delivered with the appropriate measurement and membrane selections pre-set for your application. However, you can change these settings if desired. Instructions for the various “options” included are found in section 1.4, the Modify Options Menu.
3600 Analyzer for O Measurement—Operator’s Manual It is normal for the rightmost digits to vary slightly; this is a reaction to slight variations in oxygen content. However, if drastic changes in temperature occur at the sensor while in use, correct readings will lag as the sensor adjusts to the new temperature.
3600 Analyzer for O Measurement—Operator’s Manual 1.3.3 Calibration Menus As delivered, 3600 systems are pre-calibrated. However, it is recommended that you recalibrate the oxygen sensor before making any measurements. The calibration menu permits the calibration of the oxygen sensor, as well as the instrument’s internal barometric pressure sensor and an optional external pressure sensor.

3600 Analyzer for O Measurement—Operator’s Manual H2S INSENSITIVE NO YES Note that operating in this mode requires a different sensor electrolyte, model 2961, to be used in place of the standard electrolyte. It is supplied in a pharmaceutical-type bottle with a septum that must be punctured and drawn out with the syringe supplied with your recharge kit.
Orbisphere representative may have supplied a larger, two-piece black plastic stand, model M26-5500, also designed for this purpose.) The sensor service procedure is as follows (you may also refer to the Orbisphere poster “The ABC of Sensor Service” for further illustration of this procedure).
3600 Analyzer for O Measurement—Operator’s Manual (The sensor mask may be installed as well.) Pry off the membrane holding ring either with your fingers or, if the ring has a wide outer groove, with the tool model 28116 included with your recharge kit. Take care to avoid contact with the electrolyte in the sensor.
