    The device is reliable in service when operated according to its intended use. VERY DANGEROUS! Injury or mortal danger! The equipment is not certified for the employment in areas with explosive gas air mixtures (zone 0).
  • Page 11: Introduction

    The methods described above are complicated, expensive, require specially trained personnel and can only be used in a laboratory. Using ion mobility spectrometer (IMS) a good quality assessment of the SF...
  • Page 12: Working Principle

    -Aciditor 5.1 Working Principle The SF -Aciditor is a stand-alone device designed to quickly and accurately measure the amount of sulfur dioxide (SO ) in SF . Because the unit contains an automatic flow and pressure control module, the user does not need to be concerned with setting the correct flow rate, or compensating for variations in equipment pressure.
  • Page 13 -Aciditor While the sensor must be replaced (by the user) every 2 years, its accuracy and sensitivity do not strongly degrade due to use (<2% per month). Calibration is not required. The universally accepted CIGRE B3.02.01 standard for re-usable SF is currently 12 ppm /SOF –...
  • Page 14: System Operation

    -Aciditor 6 System Operation 6.1 Loading of Battery The SF -Aciditor is equipped with a 3.2Ah Lithium-Ion battery which allows to operate the device for more than 10 hours. If the voltage which is always displayed during operation drops under 21V a warning message “Low battery” appears on the display. An automatic shutdown of the SF -Aciditor will be executed if the voltage drops under 18V.

    -filled compartment. Information! The SF -Aciditor has no internal valve. If there is an open connection to an -filled compartment, the gas passes through the device with 20 L/h. This, independently whether the device is turned on or off !!
  • Page 18 6.4. 8. Disconnect the SF -Aciditor from the SF -filled compartment. 9. Disconnect the connected sampling bag or recycling system from the “Gas Outlet” on the back of the SF -Aciditor (optional). Information! Using a recycling system or sampling bag closely watch the filling status...

    Therefore keep SF -Aciditor turned on, disconnect the hose at the gas inlet and press “Flush” on the touchpad display. The pump starts pumping ambient air through the sensor (see picture). Air has to be pumped through the sensor until the SO concentration has again reached 0 .

    -Aciditor 6.5 Settings For adjusting the settings of the SF -Aciditor press “Settings” on the touchpad display. The following screen appears. 6.5.1 Turn on/off beeper In the first menu point the beeper for all acoustic signals like keypad tones, alarm tones, etc. can be turned on and off.
  • Page 21 -Aciditor Information! Using the SO -sensor for more than two years leads to an incorrect reading of the sensor. (<2% per month of signal degradation) Pressing the left arrow on the touchpad switches back to the first menu point of “Settings”. To go back to the main screen press “Back”.
  • Page 22: Exchange Of The So -Sensor

    -Aciditor 6.6 Exchange of the sensor The SO -sensor installed inside the SF -Aciditor has a recommended lifetime of two years to guarantee a correct reading. The lifetime counter on the bottom of the screen reminds the operator when to replace it. The exchange the SO -sensor is described in detail below.
