Instrumens shows - but what ?

[stonefox]

Hello - I purchased a meter to measure water levels in aquariums, but has problems with the display on the instrument and the information I need.

At the site where it was bought says that it can measure TDS, but the instrument itself shows ppm, and I need the value in the microsiemens. how do I use these information I have, to find the micro Simens value?

In addition it appears that EC - CF and MV. what shows these values, and is one of them equal to their stowed oxygen in the water.

What I'm working with is water that has a microwave while value of 0 ~ 10, where I get some minerals which are difficult to dissolve and must be fed some CO2 for a few days until the minerals are dissolved. The water is then aerated vigorously to remove the injected CO2, the value that shows how much CO2 there is in the water and the value that can show whether it is removed again, can it be measured?

I don't really understand the last part of your post, but to convert ppm to microsiemens in regular aquarium water you divide your ppm value by 0.6. That's close enough. Some ppm meters have ways to set either ppm or microsiemens, so read your instructions to figure out if your meter can do that. All meters actually measure in microsiemens and then do the simple math above in reverse to display ppm (ppm = mg/l).
