MEASUREMENT PROCEDURE
STARTUP
Prepare the instrument for measurement as follows:
• Unpack the instrument by removing the dust protection sleeve from the instrument cuvette
holder.
• Place the battery in the instrument as described in the “BATTERY REPLACEMENT” chapter.
• Place the instrument on a flat table.
• Do not place the instrument under direct sun light.
To compensate the meter for the sample turbidity or color, the measurement takes place in two
phases. First, the meter is zeroed using the unreacted sample. After the reagents are added the
reacted sample is measured.
• Turn the meter on by pressing ON/OFF.
The display briefly shows all tags on.
• When the beeper sounds briefly and the
LCD displays dashes, the meter is ready.
The blinking “ZERO” indicates that the
instrument needs to be zeroed first.
• Fill the cuvette with 10 mL of unreacted
sample, up to the mark, and replace the
cap.
• Place the cuvette into the cuvette holder
and ensure that the notch on the cap is
positioned securely into the groove.
