Apply a force N to the tip.
When readings are almost
unchanged, press the key
'MAX' to hold the reading P

e.g. if applying 0.4 kgf to FHT-
801 or 802, the reading should
be
0.4 10.399=4.16
Max. deviation is
±(4.16*1%+0.1)=±0.14
so correct reading should lie in
×
4.16±0.14
=4.02-4.30kgf
But if applying 11.0 kgf to
FHT-803 (7.9mm) the reading
should be
11x2.041=22.45
Max. deviation is
±(22.45*1%+0.1)=±0.32
so correct reading should lie in
22.45±0.32
=22.13-22.77kgf
If the deviation is beyond its
accuracy, Depress Power key
and not release it till 'CO'
appears on the Display. It takes
about 6 seconds from starting
depressing Power key. Then
adjust the reading P by the
'MAX' key (increase) or 'UNIT'
key (decrease) to the desired
value. store that value and quit
by pressing Zero key.
