GPR-Portables Oxygen Analyzer User Manual Before using your portable analyzer Safety information Please read this manual, ensuring that you fully understand the content before attempting to setup, maintain or use the portable analyzer. Important safety information is highlighted throughout this document as follows: The electrical warning symbol indicates instructions that must be followed to avoid serious or fatal injury from hazardous voltages and electric shock.
• Operation • Maintenance and troubleshooting. • To ensure that the latest manual is being used please visit the PST website www.processsensing.com. Access the latest datasheets, user manuals, certificates and more at the product page Downloads tab. GPR-1100 GPR-1200 GPR-2000...
If contaminants are present in the sample gas, the sensor can be affected, and the validity of the measurement impacted. Please ensure that the sensor is protected, and any contamination is prevented from reaching the analyzer’s pipework and the sensor. Consult the PST sales team about our cost-effective standard sample conditioning systems. ProcessSensing.com...
With most standard electrochemical sensors, an alkaline electrolyte is used; this is neutralized over time when exposed to acid gases, such as CO . To combat this, PST has developed the XLT sensor with a special electrolyte formula, which maintains functionality in temperatures as low as -10 °C (14 °F).
Ensure the sensor selected and supplied is suitable for the gas composition to which it will be • presented; if in doubt, review the application and consult the PST Factory before initiating the installation. The products covered should be evaluated to the environmental conditions as defined by the •...
GPR-Portable Oxygen Analyzer User Manual Safety approvals and directives The Ex marking indicates the portable The CE marking indicates the portable oxygen analyzer conformity to European oxygen analyzer conforms to European Union directive 2014/34/EU (ATEX) and health, safety, safety and environmental protection directives.
GPR-Portable Oxygen Analyzer User Manual Installation NOTE: Installation, operation and maintenance of this equipment should be carried out only by appropriately trained and suitably qualified technicians in accordance with the instructions in this user manual, and any applicable standards/certificates associated with the country, industry and application.

GPR-Portable Oxygen Analyzer User Manual Set-up The analyzer is approved for indoor as well as outdoor use if the ambient temperature remains within the specified range. Please refer to "Appendix A - Technical Specifications" on page 41. This portable analyzer configuration is designed to be used on a flat horizontal surface. The analyzer’s design provides immunity from RFI/EMI by maintaining good conductive contact between the two halves of the enclosures via a conductive gasket (the smaller enclosure containing signal processing electronics).
GPR-2000 Figure 4. Gas ports The sample inlet and outlet vent gas lines for the GPR-1100 model require 1/8” PTFE / PVDF tubing. The fittings are self-sealing push-fit fittings. The sample inlet tubing for ppm portable analyzer models (GPR-1100 and GPR-1200) must be metallic, preferably stainless steel (SS).
This may be accomplished by using a back-pressure regulator on the vent line of the analyzer. If assistance is required to configure a measurement at a positive pressure, please contact PST with full application details for a review.
Figure 4 on page 10 GPR-1100 NOTE: The GPR-1100 analyzer is equipped with quick-disconnect fittings. To ensure gas is venting to atmosphere, connect the vent line to a port. Set the sample gas pressure between 5 and 30 psig (0.34...2 barg).
GPR-Portable Oxygen Analyzer User Manual Calibration gases NOTE: It is recommended that you use certified zero and span gases for calibration to ensure the best measurement readings. Cylinders of the appropriate certified zero and span gases should be made available for verification of the analyzer’s performance.
Disconnect your gas Follow the procedure below that is applicable to your portable oxygen analyzer model to disconnect your gas. GPR-1100 Disconnect your span gas line using the quick disconnect fitting. Stop the flow of gas. Now disconnect the gas line venting to atmosphere using the quick disconnect fitting.
The integrity of the sensor housing has been tested at the PST Factory prior to shipment. The analyzer must be calibrated once the installation has been completed and periodically thereafter.

GPR-Portable Oxygen Analyzer User Manual Remove the sensor from its packaging, remove the shorting flags and immediately place in the top sensor housing with the gold contact plate facing towards two gold contact pins in the top sensor housing as shown in Figure Figure 6.
GPR-Portable Oxygen Analyzer User Manual GPR-2000 To install or replace an oxygen sensor: Press to switch on your portable analyzer. Using a screwdriver, remove the four screws to open the front of the enclosure. If replacing the sensor, disconnect the sensor cable from the old sensor by turning the lock nut counter-clockwise, otherwise continue to step 5.
GPR-Portable Oxygen Analyzer User Manual Operation This section details the best practice operation for a correctly installed analyzer. Please refer to "2 Installation" on page 6 for analyzer installation guidance and gas connection. User interface The portable analyzer has a 3.5-inch LCD display and a five-key keypad interface. Figure 8.
GPR-Portable Oxygen Analyzer User Manual Initial start-up and self-test Once you press the button, the analyzer will immediately start up. The digital display responds instantaneously and will display an initial start-up screen: Figure 9. GPR-series analyzer start-up screen After self-diagnostic tests, the analyzer switches to sampling mode and displays the oxygen reading from the sensor (larger size numeric value) and the measurement range (small size font with units).
GPR-Portable Oxygen Analyzer User Manual Menus NOTE: Available menu options and sequences will vary between analyzer model and sensor type. 7.3.1 Main Menu and interface keys To access the Main Menu, press the Menu key and the following Main Menu display will appear: Figure 11.
GPR-Portable Oxygen Analyzer User Manual 7.3.2 Range selection Within the Range menu, you can select 6 options. The range is linked to the display and the 4...20 mA analog output of the analyzer. Figure 12. Portable analyzer Range and Default Range displays NOTE: For trace oxygen analyzers, the range 0...25 % is for air calibration purposes only.
GPR-Portable Oxygen Analyzer User Manual It is recommended that you set your preferred default range for the analyzer. Figure 13. Default Range display Measurements outside manual range If the oxygen reading goes above the manual or auto range maximum value, the values will be displayed up to 10% above the maximum range.

GPR-Portable Oxygen Analyzer User Manual Subsequent span calibrations will fail if the output is lower than 80 % of the first span calibration, if it drops by 30 % of the first span calibration, or if it increases above the first span calibration by 15 %. This could be caused by a bad first calibration or a bad sensor.
NOTE: The correction value does not relate to actual readings it is a proportional value. This value can be used by the PST Factory for diagnostics. Reset calibration This function will reset both span and zero calibration information to default values. It will not clear the Calibration Log.
