Industrial Scientific Ventis MX4 Calibration Guide:

Want to calibrate the Industrial Scientific Ventis MX4? Here's how:

  1. Turn the Industrial Scientific Ventis MX4 on in normal reading mode. Do this by pressing and holding the power button on the left until you hear a beep.

  2. For a pumped monitor:

    1. Screw the demand flow regulator into the calibration gas cylinder.

    For a passive diffusion monitor:

    1. Open the valve on your fixed flow regulator. This is a very important step so you do not ruin your calibration gas cylinder. Now screw it in to your calibration gas cylinder. Close the regulator once you hear gas spewing out of it. This is the signal to know your regulator is good to close. Continue screwing in the regulator until it stops. Do not overturn it.

    2. Attach the tubing to the hose barb on your regulator. Make sure the tubing is also connected to your calibration adapter.

  1. Once Industrial Scientific Ventis MX4 is in normal reading mode, you need to set it into fresh air calibration mode. Press the power button once to see the number of days since the last calibration then press it again to see the zeroing out process screen. Make sure you are in a fresh air environment and then press the enter button on the right to start zeroing out the sensors.

  2. Once it beeps to signal it's done zeroing the sensors, press the power button to send it into calibration mode.

    For a pumped monitor, put the tubing into the input port on the top of the monitor.

    For a passive diffusion monitor, slide the calibration adapter on top of the monitor then open the regulator to allow gas to flow.

  3. Once the calibration completes it will flash "P" next to each value to tell you that it is successfully calibrated. Make sure all the values have a "P" and your calibration gas values on the screen match what is on your calibration gas cylinder.

  4. Close and unscrew the regulator. If using a passive monitor, slide the calibration adapter off the monitor. Otherwise disconnect the tube from the input port.

  5. Congratulations! You have officially calibrated your Industrial Scientific Ventis MX4 gas monitor. Make sure to record these readings in your calibration log!
