Measurement

Considerations

measurements

should

meet

the

published

accuracy

specifications.

2.

Strong

magnetic

fields

can

affect

the

readings.

3.

When

using

the

statistical

analysis

functions

for

obtaining

a

mean

value,

take

several

readings

of

the

same

measurement

area.

False

readings

or

outliers

can

then

be

removed

(deleted)

using

the

programming

menu.

4.

The

final

reading

is

derived

from

a

statistical

calculation

with

regard

to

the

meter’s

published

accuracy

specifications.
