Saving measurement values during correcting the reference
value of the sensor and power off
Steps 9, 12 and 14:
"Data keep" screen asks whether or not you
want to save the measurement values during
setting internal constants.
Select "Yes" to save measurement values
and turn power off. When power is turned on
again and page 1 of the Config. menu is
selected, Screen Status at last power off is
displayed.
Select "No" to cancel measurement values
and turn power off.
Difference calculations:
Step 15: If the tripod is turned and repeat measurements taken:
Value at position A = {[(1st reading on staff a) + (1st
reading on staff b)] + [(2nd
reading on staff a) – (2nd reading
on staff b)]} / 2
Value at position B = {[(1st reading on staff a) + (1st
reading on staff b)] + [(2nd
reading on staff a) – (2nd reading
on staff b)]} / 2
Difference = absolute value of [(value at position A) –
(value at position B)]
If the tripod is not turned and only one set of
measurements are taken:
Value at position A = [(reading on staff a) – (reading on
staff b)]
Value at position B = [(reading on staff a) – (reading on
staff b)]
Difference = absolute value of [(value at position A) –
(value at position B)]
