Page 9: Introduction
Introduction The portable M&C oxygen analyzer PMA10(S) is a non-thermostated instrument which has been designed for continuous and discontinuous measurement of oxygen concentrations in dry and particle-free sample gas. Serial number The type plate with the serial number is located on the back of the analyzer. Please refer to this serial number if you have any questions about your PMA 10(S).or if you need to order spare parts or consumables. -

Page 12: Front Panel
The analyzer is not thermostated and should be operated only in areas with con- stant ambient temperature. If this is not possible, the analyzer has to be calibrated before every measurement, to guarantee the accuracy of measurement. Note Figure 1 Dimensions Front panel Analog/digital indication... -

Page 14: Sample Gas Pump
9.3.4 Sample gas pump A sample gas pump with a capacity of approx. 1 l/min – without pressure can be integrated in the device. The pump is designed for short time rating only. For long-term operation an external sample gas pump has to be be used. -

The measuring cell consists of two nitrogen-filled spheres which are arranged in the form of a dumbbell. In the dumbbell’s central point of rotation, a small mirror is placed. The dumbbell is surrounded by a wire coil needed for the compensation procedure. The described system is fixed rotationally symmetrical inside a glass tube via a tightening strap out of platinum ... -

In case of outdoor operation protect the analyzer against sun, wind and rain. At the installation location constant climatic ambient conditions (pressure, temperature) are necessary to prevent a distortion of the measurement and Caution a condensation in the measuring cell in case the ambient temperature is fall- ing below the dew point temperature of the sample gas. -

• Check electrical connections and gas connections. • Switch on mains voltage. • Turn measuring range selection switch from ‘0’ to the desired measuring range. The analyzer is ready for operation immediately. Caution If during transport the analyzer was exposed to extreme changes of temper- ature, an adequate time for temperature adaption has to be observed, to pre- vent condensation in the device. -
Page 21: Calibration
Calibration The accuracy of an analyzer mainly is dependent on its calibration. Before calibration it has to be assured that the calibration conditions corre- spond to the conditions during measurement. The flow rate, the ambient temperature and the barometric pressure conditions have to be constant. Un- Note der this terms a calibration of the analyzer is necessary aproximately one time a week to maintain the accuracy. -

Therefore, a con- version must be maid to the effective volume concentration. In principle, the following is valid: Table value x Volume concentration Effective cross sensitivity = [vol%] For the components of the gas mixture, the following values are found:...

Page 25: Span Calibration
18.2 Span calibration Before span calibration a finished zero calibration is necessary. Connect a flexible PVC- or FEP-hose with the pressure reducer of the N -zero-gas bottle. The pressure reducer should have an output control range of max. 0–1.5 bar abs.. Caution The outlet pressure is only allowed to be adjusted at max. -
Page 26: Measuring
Se = Final value, signal output Snp = Zero, signal output 13. Shut off pressure reducer output valve and bottle valve 14. Disconnect hose connection at the analyzer. The span calibration is finished. If during the span calibration great variations have to be compensated (>2 % O ) at the potentiometers, a second zero and span calibration is reasonable. -
Page 27: Maintenance
Maintenance The analyzer, woking with a physical measuring principle, requires no intensive and complex maintenance. But the preceding components necessary for the sample gas conditioning are to be maintained with special attention according to the respective operating manuals. The calibration of zero and span is to be effected with the corresponding test gases according to stability of the operating conditions and to the demands on the accuracy. -
