The following are some common messages that may be displayed, including error messages. If an
error message other than those listed below is displayed, please contact technical support in the USA
at (803) 329-0162 (ext. 0).
LCD Message Description
HI In READ mode: test sample concentration is above
the measurement range (test specific).
LO In READ mode: test sample concentration is below
the measurement range (test specific).
LO In ZERO mode: sample absorbance (due to a
cloudy or colored sample or a dirty cell) is too high
to zero, the meter will read "LO".
ER Excessive stray light detected. Normally this
does not occur, even when testing in sunlight.
Low battery indication.
The built-in CELL is transparent plastic and, when filled to the top, contains 4ml. The sturdy CELL design
will last for over 20,000 readings. Scratches on the CELL will not interfere or compromise the accuracy of
the readings because of its fixed position. For best accuracy, rinse cell with clean water immediately after
a test is completed. Do not use solvents, such as acetone, to clean the cell. When the CELL becomes
stained or cloudy from repeated testing, or when the meter does not blank when you press the ZERO/ON
button, the cell needs to be cleaned. Clean as follows: Fill cell with clean water and move the Cell
cleaning brush up-and-down and back-and-forth along the walls of the cell. Afterwards, rinse the cell and
the meter is ready for use again. Cleaning the cell regularly is especially recommended after you run a
test that is using turbidity or precipitation chemistry for analysis (Calcium Hardness and Cyanuric Acid).
To Install/Replace "AAA" Batteries:
1. Unscrew the O-ring sealed battery cover counter-clockwise. Use proper sized pliers if necessary.
Do not disturb the sealing O-ring. Batteries are not included.
2. Remove the used batteries and install 4 new AAA batteries following the diagram for
correct polarity (see diagram). We recommend high quality AAA alkaline batteries be used.
4. Replace the battery cover. Be sure to tighten the cover securely. This is necessary for meter to
be waterproof.
5. Dispose of the used batteries in accordance with your
local regulations.
6. Press ZERO/ON button to confirm the meter turns on.
The meter is now ready for operation.
7. Meter will not work if battery orientation is incorrect.
