  • Page 10 PRODUCT FEATURES A flexible gooseneck is used to assist in locating the source of gas leaks and for remote sampling. A water/dirt trap is located at the end with a convenient luer style connector to attach sampling and probe accessories. A two line display continuously updates the operator of all available gas concentrations and alarms simultaneously as well as indicates internal functions such as air flow and battery power.

  • Page 11: Sensor Types And Pumps

    0-100ppm. All gases are displayed simultaneously on the display. The Pump The SENSIT® GOLD CGI instruments are equipped with a powerful and efficient diaphragm pump. A water/dirt filter at the end of the gooseneck protects the pump from foreign material. An additional internal filter also helps to protect the pump from damaging debris.

  • Page 12: Battery Installation/Replacement

    BATTERY INSTALLATION/REPLACEMENT Battery replacement is necessary when the display reads BAT LOW, an audible alarm sounds and the green ready LED flashes. When the instrument remains in BAT LOW, a count down will appear starting at 300 seconds (5 minutes) which is the maximum time remaining before shut down.

  • Page 13: Operation And Use

    OPERATION AND USE ⚠ CAUTION: Always start any SENSIT® GOLD CGI in a gas free environment to insure a proper zero. 1. Push the POWER/MUTE BUTTON (A). The following start-up sequence will be displayed. a. Product name and model version number b.
  • Page 14 OPERATION AND USE As an option, the instrument is capable of displaying a range of 0.1% LEL up to increments as high as every 2% LEL. An alternative option is to request a PPM display. Resolution for this option is 1ppm or every 10ppm.
  • Page 15 Carbon Monoxide - 35ppm per utility industry standards d. Hydrogen Sulfide - 10ppm and above per Federal OSHA guidelines ⚠ CAUTION: There are gases that can poison or be cross sensitive to the combustible gas sensor. Contact SENSIT Technologies for information regarding “LEL Cross Sensitivity”.
  • Page 16 OPERATION AND USE 11. To disable the alarm, quickly press the POWER/MUTE BUTTON (A). To enable the alarm press the same button again. During an alarm the gas that has exceeded the preset alarm point will flash on the display and the HAZARD 3 LED will flash indicating a potentially unsafe condition.
  • Page 17 OPERATION AND USE 13. At any time the operator may save the readings on the display by pressing the ZERO/SAVE (C) button. This will save all readings for download at a later time. The memory is factory set to store 6 events. This can be adjusted from 1-1000 at the factory.

  • Page 18: Calibration Check

    CALIBRATION CHECK To verify the accuracy of any SENSIT® GOLD CGI, it must be exposed to a known concentration of test gas that will test any sensor combination included in your particular model. Any sensor that does not meet the specifications listed in this manual may require calibration or repair.

  • Page 19: Bar Hole Test

    BAR HOLE TEST To assist pinpointing the location of underground leaks the Bar Hole Test feature may be used. This feature will draw a timed sample (45 seconds) and display sustained and peak readings. NOTE: Use an approved barhole probe with filter to prevent damage to the instrument when conducting bar hole surveys.
  • Page 20 BAR HOLE TEST The peak percent of gas by volume detected will be displayed on the right. At the conclusion of the test, the pump will shut off and any sustained and peak readings will be shown and recorded. If you have another test to take, press & hold the SAVE/ZERO BUTTON (C).
