Faith, It is very easy. See: http://www.ozelink.com/tds_meters/how_to_use.htm However TDS meters don't measure colloidal silver directly and so you need to multiply the reading on the TDS meter by a constant to get an estimate of the colloidal silver ppm. I have seen it recommended that you multiply the TDS reading by 1.2 (Colloidal Silver Master manufacturer) up to multiply by 2.0 (colloidalsilver.com) to get the colloidal silver ppm. I have been using 2.0 but may change closer to the 1.2 to be conservative. I am not sure how importance absolute accuracy is if you are primarily looking for consistency and to verify setup operation. Question for the group: What multiplier do you use and how accurate do you think your measurements are???
Just make sure the TDS meter probe is not contaminated when measuring, make sure there are no bubbles on the probe tips and do not try to measure moving water (keep TDS meter still in water). - Steve >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>..
