I meant DW not DS below. ________________________________
Is there any chance you have contaminated DS? This could explain the low level of CS if it is contaniminated but not bad enough to trip the water quality monitor in your generator. It could also be that the unit isn't operating correctly. I think your observations of a faint beam with the laser pointer indicates low ppm CS. Is there anything you are doing during the process, such as cleaning the electrodes that could cause contanimation? You could also try running the same batch twice if the generator will let you. With a digital multimeter you could check your setup for voltage and current: http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=92020 <http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=92020> Or get a TDS meter: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=170250480664&ssPageNa me=MERC_VIC_RSCC_Pr12_PcY_BIN_Stores_IT&refitem=170239081511&itemcount=1 2&refwidgetloc=closed_view_item&usedrule1=StoreCatToStoreCat&refwidgetty pe=cross_promot_widget&_trksid=p284.m183&_trkparms=algo%3DDR%26its%3DS%2 52BI%252BSS%26itu%3DISS%252BUCI%252BSI%26otn%3D12 <http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=170250480664&ssPageN ame=MERC_VIC_RSCC_Pr12_PcY_BIN_Stores_IT&refitem=170239081511&itemcount= 12&refwidgetloc=closed_view_item&usedrule1=StoreCatToStoreCat&refwidgett ype=cross_promot_widget&_trksid=p284.m183&_trkparms=algo%3DDR%26its%3DS% 252BI%252BSS%26itu%3DISS%252BUCI%252BSI%26otn%3D12> It might be worth the expense. - Steve
