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 4.0
mg/L iron and a representative lot of reagent, an
operator obtained with a single instrument a standard
deviation of
0.4 mg/L.

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.
