Automatic calibration function Automatic calibration using standard solution (Dilution water is used as the zero standard solution for zero-calibration.) Options can be attached to use up to eight standard solutions and to permit automatic calibration with up to a 5-point multi-point calibration curve.
Stream switching function Streams 1 to 6 can be switched (with the relevant option)
Display, operation Color LCD with touch screen
Conversion function Conversion with a linear expression using required indices (Conversion expression must be determined in advance.)
Load calculation function Using the analog input board (option) permits load calculations. (Non-isolated analog inputs; load resistance: 100 ohms)
EPA TOC removal rate calculation function TOC removal rate calculation according to the United States EPA regulations (Part IV 40 CFR Part 9, 141 and 142, 1998) (when a 2- or more-stream switching option is provided)
Data storage function Store 20,000 past on-line measured values (equivalent to one year's data at 30-minute measuring cycle).
Offers trend graph displays.
Data storage device Store measured values or measurement conditions to USB memory*3. (USB 1.1 or 2.0 USB memory; FAT16 or FAT32; no encryption)
Recorder Recording width 100 mm, 6-dot recorder (optional)
Printer Thermal printer, 40 characters per line; 110 mm chart width (optional)
Analog output Selectable between 4 – 20 mA DC or 0 – 16 mA DC (isolated outputs) With attached option: Up to 12 outputs (load resistance: 500Ω max.)
