procedure. Calibrations generated with deionized water as the zero will give
less accurate results if the reagent blank is significantly more turbid or colored
than deionized water. Use the deionized water or the reagent blank as the zero
concentration point (S0) in the following calibration procedure.
1. Turn on the instrument and select the range to be calibrated. An arrow at
the top of the display will point to the selected range. To change ranges,

MENU key, then use the READ/ENTER key to toggle between
ranges 1 and 2. Press
MENU again to return to measurement mode.
