    OPERATION AND USE ⚠ CAUTION: Always start any SENSIT® GOLD 100 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 An alternative option is to request a PPM display. Resolution for this option is 1ppm or every 10ppm. An X on the display indicates that the instrument is not outfitted with that sensor. 6. Prior to use, test the integrity of the sensor cap and tubing. Use your finger to block the inlet of the sensor cap for 4-5 seconds.
  • Page 15 OPERATION AND USE 10. When sampling areas the appropriate sensors will cause the display to update when a gas is encountered. Additionally, if a combustible gas is encountered a series of LEDs on the front of the instrument will illuminate when the preset concentrations are reached.
  • 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.
