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.

• 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 one cuvette with 1 mL of unreacted sample, by means of the syringe.

• Turn the meter on by pressing

ON/OFF

. The display briefly shows all tags on.
