To compensate the meter for the sample turbidity or color, the measurement takes place in two

phases. First, the meter is calibrated. After the sample is prepared, the sample is measured.

• When the beeper sounds briefly and the

LCD displays dashes, the meter is ready.

The blinking “CAL” indicates that the

instrument needs to be calibrated first.

• Fill a standard 10 mm tube with

1.5 ml of the blood sample.

• Use a centrifuge to separate the blood

cells from the plasma and to obtain a

clear supernatant of plasma, without any

turbidity or suspended blood cells.

• Please verify that the height of the

deposits does not exceed 12 mm (from

the bottom of the tube), and that the

tube is filled with plasma, up to, at

least, 19 mm.

MEASUREMENT PROCEDURE

• Turn the meter on by pressing ON/OFF.

The display briefly shows all tags on.
