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
1.00 mg/L chlorine and a representative lot of
reagent, an operator obtained with a single
instrument a standard deviation of 0.02 mg/L.

Battery replacement must only take place in a
non-hazardous area.
Simply slide off the battery cover on the back of
the meter. Detach the battery from the terminals
and attach a fresh 9V battery while paying attention
to the correct polarity. Insert the battery and replace
the cover.
