All modifications performed in this menu will affect the measurement values. If false manipula-
tions are done, measurement values will be wrong.
“Service / Calibration”
screen is displayed.
• Tap
“Perform Calibration”
.
• Enter the code to access to calibration.
To get your code, please contact the Service Contact. Our team will explain how to get this code.
• Tap
''Access Calibration''
.
• Select the gas sensor on which the calibration must be applied.
• Enter the new reference value then tap Start.
The analyzer performs the measurement for a defined time and displays the following information:
• Measurement
• Sensor current
• Reference value
• During the measurement, if values are correct, tap
“Validate adjustment”
on the bottom of the screen.
• Tap
“Save adjustment”
to apply the calibration on the gas sensor.
• Tap
“Restart analyzer”
for changes to be taken into account.
11.2 Gas sensor information
This screen gives information about the gas sensor installed on the analyzer.
“Analyzer information”
screen is displayed.
• Tap
“Gas sensor information”
.
• Tap the gas sensor on which information must be displayed.
The following information is displayed:
• Type of sensor
• Measuring range of sensor
• Date of last calibration
• Date of installation
• Output current (in units of micro amps)
• Sensor life estimation: a four bar display is shown. When down to one bar, it is recommended to contact an authorized
Sauermann service center
11.3 Other information
Analyzer information screen also gives the following information:
• Model number / Serial number
• Firmware version
• Battery status
• Memory status
Please provide the model number and serial number for contact with the manufacturer or the Service Center.
12. Perform other measurements
The analyzer can perform other measurements than a gas analysis:
• CO monitor
• Gas tightness test
• Gas/pump flow rate
• Heat exchanger integrity test
• Stack gas velocity
12.1 Perform CO monitoring
The CO monitoring is performed with the external CO probe (available as option) or with the internal CO sensor.
• Connect a CO probe (available as option) on the DIN connection on the bottom of the analyzer (if the CO probe is
used).
• Turn on the analyzer.
• Tap
“Menu”
then
“Other Measurements”
.
• Tap
“CO monitor”
.
The measurement is launched, the instrument displays the current level of CO, the maximum level of CO, and the duration
of the test. The maximum CO level and duration are reset each time the CO Monitor screen is entered.
If the internal sensor is used, the main pump will be ON and if the CO probe is used the main pump will be OFF.
12.2 Perform a gas tightness test
To perform this test, it is necessary to have a Differential pressure hose kit. This kit is available as option (ref: KEG3).
12.2.1 Perform a gas tightness test according to UNI 7129 (new piping)
• Connect the hose to the gas analyzer P+.
• Connect the hose to the piping system.
• Select the piping system: UNI 7129 (new piping)
• Select the estimated volume: < 100 dm
3
, 100-250 dm
3
or 250-500 dm
3
.
• Select the fuel: natural gas or LPG
• Pressure the pipe up to 150.00 hPa.
• Tap
“Start stabilization”
.
The analyzer starts the stabilization which takes 15 minutes.
At the end of the stabilization, the analyzer starts the test and then displays the following results:
• P1
• P2
• Pressure drop
• Pressure drop allowed
According to the results, the analyzer will display if the test is compliant or not compliant.
12.2.2 Perform a gas tightness test according to UNI 11137 (existing piping)
• Connect the hose to the gas analyzer P+.
• Select the piping system: UNI 11137 (existing piping)
• Select the test type: Preliminary test (< 18 dm
3
) or Indirect test (>18 dm
3
up to 35 dm
3
)
