 HELPFUL HINTS
»
Pair the device to the phone, then leave the device on for the duration
of the day for reliable, consistent pairing. Turning the meter off and on
frequently can cause connection issues between the device and the
paired phone or tablet.
»
High Chlorine/Bromine - High sanitizer levels may cause the DPD
reagents in the disk to bleach out to a colorless or near colorless
solution. Wide Range pH/Total Chlorine Test Strips (2987-G) capable
of testing high concentrations of chlorine can be used to determine the
approximate level of sanitizer. Note: At high sanitizer levels, chloramines
could break through into the Free Chlorine test, the pH reaction may
turn purple and the Alkalinity reaction may turn yellow.
»
High Copper - Copper at levels above 1.0 ppm may cause the
Hardness test to read low.
»
Low Alkalinity - Algaecide treatments above recommended levels may
lower the alkalinity results.
»
Cyanuric Acid - Since Cyanuric Acid tests are temperature dependent,
the best results are obtained when sample temperatures are between
70 and 80 degrees. Below this range, results may read high, while in
temperatures above the range they may read low.
»
pH Purple - As noted under High Chlorine/Bromine above, sanitizer
levels beyond 10 ppm can turn the pH reaction purple.
»
Low Hardness - High Copper, low pH and salt can signifi cantly reduce
the expected hardness results. For precise Hardness results in sample
water containing salt choose the Chlorine Generator product from the
Sanitizer drop down bar in the water analysis program.
