directly measure bleach concentration in the range of 0 to 15%. No reagent is required
for the method and the displayed result is the sodium hypochlorite concentration in
percentage.
Select BLCH in the method selection page and carry out the following steps:
1.
Place a vial filled with deionized water into the vial compartment and press the
ZERO button to zero the AP50MM.
2.
Discard the deionized water and fill the same vial with the bleach sample. Place
the vial into the vial compartment and press READ button to read. The measured
bleach concentration will be displayed in the top of the method page.

5.8.2. Slope Calibration
If the method has been calibrated prior to shipping, there is no need to calibrate unless
a calibration check indicates that the method needs a calibration. The following steps
are used to calibrate a method:
1.
Use a calibration standard of known concentration. Follow the steps required
by the method and note the value reported by the AP50MM.
2.
If the measured value differs from the known standard value, Press the
