Calculation Function
The internal measurement value (R.V.) for the "main unit" and the "expansion unit
additionally installed next to the main unit (referred to as expansion unit 1)" can be
calculated (addition or subtraction).
If there are more than one expansion units, the calculation function can be used between
the "main unit" and the "expansion unit 1" only.
There are three calculation modes for the calculation function.
• Addition Mode
• Subtraction Mode
• 2 heads Mode
The calculation result of the internal measurement value (R.V.) for the "main unit" and the
"expansion unit 1" is referred to as calculation value (CALC value).
The "main unit" operates with the calculation value (CALC value) considered as a judgment
value (P.V.).
The "expansion unit 1" operates with its internal measurement value (R.V.) considered as a
judgment value (P.V.).
Note • If the measurement mode for the main unit is set to the "Pin interval
judgment mode" or "Pin diameter judgment mode", the calculation
function cannot be used. If the measurement mode for the expansion
unit 1 is set to the "Pin interval judgment mode" or "Pin diameter
judgment mode", the mode is automatically changed to the "Edge
control/Positioning mode".
"1. Measurement mode" (page 4-8)
• When the calculation function is used, if the average number of times
of expansion unit 1 differs from the one of main unit, it is
automatically changed to the same setting as the setting for the main
unit.
• When the average number of times "hsp" is set, the update timing of
the internal data on the main unit and the expansion unit does not
match. Therefore, when a moving object is measured using the
calculation mode, the measurement value may greatly differ from the
actual value.

Calculation Value (CALC value)
Reference • The calculation value (CALC value) can be displayed on the sub display
(lower level) on the main unit.
"Sub Display (Lower Level)" (page 3-4)
• When the hold function is used, the calculation value (CALC value) is not
held.
