SPECIFICATIONS

Precision is how closely repeated measurements agree

with each other. Precision is usually expressed as

standard deviation (SD). Accuracy is defined as the

nearness of a test result to the true value.

Although good precision suggests good accuracy,

precise results can be inaccurate. The figure explains

these definitions.

In a laboratory using a standard solution of 2.0 g/L

tartaric acid and a representative lot of reagent, an

operator obtained with a single instrument a standard

deviation of

0.1 mg/L.

PRECISION AND ACCURACY

Battery replacement must only take place in a non-

hazardous area.

The blinking “ ” will appear when the batteries power

gets low.

When batteries are completely discharged, “0% bAtt”

will appear and after two seconds the instrument is

switched off.

Remove the battery cover from the bottom of the

instrument and change the old batteries with 4 fresh

1.5V batteries, paying attention to the correct polarity.

Replace the cover.
