  • Page 19 Functions from the Menu: • Button Function: o Left Button: starts the menu of choices o Right Button: confirms menu choices • First (home) screen is your monitoring screen which shows your 4 gas readings. • Press the left button to cycle through the various functions.
  • Page 20 Functions from the Menu: • Function #1: Calibration o Symbol: A Calibration Cylinder o This indicates the number of days since last calibration.
  • Page 21 Functions from the Menu: • Function #2: Zero Out o Once you confirm your choice, a clock appears and the unit will self zero out. o Zero in fresh clean air o Meter Will:  Count down for 15 seconds, then beep ...
  • Page 22 Functions from the Menu: • Function #3: PEAKS o This function will display the following:  The highest readings of the 3 gases  The lowest reading of O  *All PEAKS readings are since the unit was last turned on. o To clear PEAKS, press the right button again, or shut off detector.
  • Page 23 Functions from the Menu: • Function #4: TWA o Symbol: TWA at bottom of screen o This function will display the Time Weighted Average of CO and H S for 8 hours.
  • Page 24 Functions from the Menu: • Function #5: STEL o Symbol: STEL at bottom of screen o This function will display the Short Term Exposure Average for CO and H for 15 minutes.
  • Page 25 System Shutdown: • Hold the Power (left) Button for 5 seconds • While holding the power button the unit will beep 5 times then shut off. • Do not let go of the power button until the screen powers down and beeps stop.
  • Page 26 Pump Operation: • Flow Rate: o 0.5 SCFH (Standard Cubic Ft. per Hour) o .25 Liter per Minute • Tubing: Clear Urethane Hose o Standard Length: 10 feet o Maximum Length: 100 feet o Hose comes with Hydrophobic Filter **Do Not Use Medical Tubing: it absorbs hydrocarbons.**...

  • Page 28 Sensor Replacement: • Smart Sensor Technology • 2 Year Warranty on all Sensors • All sensors are field replaceable...
  • Page 29 Calibration: • A calibration must be performed at least once a month. • Calibration: adjusts the range of the sensors to ensure full potential; the gas in the cylinder will be matched with the sensors.
  • Page 30 V-Cal Calibration Station: • Calibration, bump tests and charging terminal all in one. • Simple one button operation. • Includes software for improved data logging.
  • Page 31 Before Taking Readings: • Meter Must Read: o LEL: 0% o CO: 0 PPM : 20.9% S: 0 PPM o The meter will attempt to “Zero Out” to these numbers, but a manual Zero Out may be performed if necessary.
  • Page 32 • Always start your gas meter before entering the potential IDLH environment. • Most detectors have 3 sensors, with 1 doing double work. The Ventis MX4 has 4 stand alone sensors for added reliability.
