3.3.4 Setting the Origin (PRESET)
This section describes how to set the absolute origin for measurement (preset value). You can
use a calibrated reference gage or master gage to set a reference plane outside the instrument’s
measuring range as absolute origin.
• To set the preset value, press [PRESET/SET] key3 in the normal mode. The
previously set preset value appears and "P" blinks in the display.
• To set a new preset value, press and hold the [PRESET] key for 2 seconds to
select which digit to set. The blinking digit can be set. Give the [PRESET] key a
short press to increase the value of the blinking digit.
• While "P" is blinking, give the [PRESET] key a short press to set the new preset
value. This value is stored in memory as the distance (origin data) from the
absolute origin to the current position of the contact point.
For example, to measure a length which cannnot be measured by the instrument alone, as
shown in the diagram, set the absolute origin with the bottom end of the master gauge as the
measurement reference (0.000 mm.). When the calibration value of the master gauge length is
approx. 100.002 mm. and the contact point is contacting the master gauge, set the calibration
value to the preset value (origin position setting) by the following procedure.
“_” mean blinking the digit.

NOTE
After starting to set the preset value, pressing [ZERO/ABS] before the new preset
value has been fixed returns the instrument to the condition it was in before the setting
(returns to 99.876 mm. or 5.432 mm. in the above example).
If the instrument is turned off and on during preset or tolerance setting, the value being
set is erased and the gage returns to the condition it was in before setting.
