y Calculatingthedi󰀨erencebetweentwomeasurementvaluesstoredinmemory
Thetwomeasurementvaluesarestoredintheproduct'sinternalmemory,andthenthedi󰀨erence
is calculated.
Thisisappropriateforcalculatingthedi󰀨erencebetweenmeasurementvalueswhentheprevious
two methods cannot be used.

3.1.1 CalculatingtheDi󰀨erencebetweentheCurrentandPrevious
MeasurementValues
Intheregularcondition,thedi󰀨erencebetweenthecurrentmeasurementvalueandthepreviousmea-
surement value is displayed in the bottom row of the LCD.
Thissectionexplainstheprocedureforcalculatingthedi󰀨erencebetweenmeasurementvalues(s2–s1,
s3–s2) when the height is measured in the order of s1, s2, s3 after the surface plate is set as the origin
(ABS measurement system) as shown below.

s2
s3 - s2
s2 - s1

Origin
(ABS measurement system)
1
Set the surface plate as the origin (ABS measurement system).
For details about the setup, see "●Settingthesurfaceplateastheorigin"onpage13.
2
Measure the height of s1.
For details about measuring height, see
"2.2 Measuring the Height" on page 21.
» The measurement value for s1 is displayed.
3
Measure the height of s2.
» The measurement value for s2 is displayed in the top row,
andthedi󰀨erencebetweens2ands1isdisplayedinthe
bottom row.
