Can a standard adjust be performed on a Hach spectrophotometer when using TNTplus® chemistries?
Standard adjust using TNTplus® chemistries
The standard adjust option referenced in Hach’s spectrophotometer user manuals is not applicable to all TNTplus® chemistries. To check if it is an option, insert the TNTplus® vial into the instrument, select Options, select More, and look for the Standard Adjust option. If it is not found in this menu, the option is not available for that chemistry.
