1. Verify gas blend and expiration date.
2. Press and Hold Middle Button wait for screen lights up then release.
3. Press the left button 2 times.
4. Press the right button, and wait for zero to complete.
5. Press the right button again to begin calibration.
Calibration Gas for the Industrial Scientific Ventis MX6 is:
25ppm Hydrogen Sulfide
100ppm Carbon Monoxide
25% LEL Pentane (or 50% LEL Methane, which we recommend)
19.0% Oxygen
Nitrogen Balance

I am having trouble getting my oxygen to pass. I am in very clean air and calibrate the monitor. Every time I turn the monitor on, it goes through the initial sequence, but the oxygen always fails. What route do you recommend?

[@Idealcalibrations]

Hey there, think we just spoke on the chat on our website. I'd recommend replacing the Oxygen sensor. Forgot to mention: Make sure once you install it you wait an hour for the sensor to stabilize and get used to the new environment, otherwise it won't work properly. Take care and let us know if you have any questions

So I turned on the monitor, and it gave me an oddly low O2 reading (~7%) but I was going to cal it anyways. It passes the cal, says 20.9% O2, but it still in alarm. I bump-test it, and it passes that, and now reads out with a "b F" for O2, but after 3 more cals, it still passes, and REMAINS in alarm. What do you suggest?

[@Idealcalibrations]

Hey Zooks, did you bump test it using the software bump test on the unit or just do it manually by applying gas? b F indicates a bump failure. Gas is the proper blend? Sometimes people buy the old ISC mix that was for the M40 and has 19% Oxygen instead of 18% and then the unit will pass cal (it cal's O2 during Zero to room air) but will fail O2 on the bump test. Give us a call if you want to troubleshoot a bit more.

Does it provide any kind of certificate with the values measured in the calibration, device status and etc? How do I get those certificates (Throught some software?) and what accessories should I have to get it? Thanks!!!

[@Idealcalibrations]

Hey there, Industrial Scientific does sell software for this purpose, and also an automated bump/calibration stand. Their iNet program is a web based server side tracking system which might be of interest to you as well.

How to connect smart keypad to the monitor?

[@Idealcalibrations]

Hello, not sure what you mean, there's no keypad available for this device, sorry!

Whats the flow rate for that demand flow regulator?

[@Idealcalibrations]

Hey Nikola, big fan of your work, demand flows match the flow of the pump (which should be around 0.5lpm in this case). However, because pumps vary, that can be a range around there, like 0.3lpm - 0.7lpm. The regulator itself has a range of 0.1lpm - 3.0lpm per the manufacturer's spec.

[@adeafblindman]

Vary helpful, thank you

[@GregLiguori]

didn't see you actually turn the gas valve on

[@Idealcalibrations]

Hey Greg, this is a demand flow regulator, which means that when you apply a vacuum (from the pump on the monitor) to the out port, the regulator opens the valve itself, releasing the gas at the correct flow for the pump. Using a fixed flow regulator (one with a valve that you turn or switch on and off) can damage pump motors and seals because they either release too much gas, putting pressure on the pump seals, or too little, which causes the motor to work harder than it needs to, causing your motor to burn out faster.

[@Xavancex]

Its a demand regulator of course not.......

[@kimberleeraymond2631]

Sure woulda been nice had ya turned the gas on!!!!!

[@Idealcalibrations]

Hey Kimberlee, I'm not sure what you mean. The regulator in use here is a demand flow regulator, so it doesn't need an on/off valve. It provides gas when there is a vacuum applied to the regulator (from the pump of the gas detector). If you have an on/off fixed flow regulator, I'd recommend you make sure and use a bleed valve during the calibration unless you're using a diffusion MX4 instead of a pumped MX4.
