3. Preparations before Use
1) Checking items before use
• Before using the product, confirm that the plunger moves smoothly.
• Confirm that the displayed value is stable at the position you have set.
Body temperature or changes in air temperature may cause thermal expansion or contraction of
parts such as the plunger, changing the displayed values.
• For precision measurement, wear thick gloves in order to reduce changes in the displayed value
caused by the transmission of body temperature.
2) Mounting the extension rod (standard accessory)
Use this if the measurement location is deep enough that the contact point cannot reach it.
Multiple extension rods may be combined depending on the measurement being made.
• If the total length of multiple extension rods is 110 mm or more, make sure to use in the vertical
orientation (contact point facing down). Plunger operation may be affected.
• When removing or mounting a contact point or extension rod, apply a soft cloth such as felt to
the knurled part (if not knurled, to the area near the plunger), and then use pliers or longnose
pliers.

• The preset value is automatically converted when the unit system or resolution is changed. In
this case, however, a conversion error may be produced. It is therefore recommended to check
the preset value after changing the unit system or resolution.
3) Detecting peaks
During peak detection, measurement is performed by moving and rotating the workpiece while it is
gripped. The displayed value can be switched between the runout width (TIR), the maximum value
(Max), and the minimum value (Min) detected as the displacement peak value.
●Current value display
Current measurement value is always displayed.
●Runout width (TIR) display
The runout width (maximum value - minimum value) is always displayed relative to the displacement
of the measured value. [Max] or [Min] blinks when the maximum and minimum values are updated.
Tolerance judgment results are displayed with respect to the runout.
Tips
• When [Auto] is selected in "Analog bar display selection" in the parameter setting mode, the
analog bar scale automatically changes so that the pointer of the analog bar is always within
the display range with respect to the displacement of the measured value.
•
For tolerance judgment, the set upper/lower limit width is compared with the measured runout width.
● Maximum value (Max) display
The maximum value is always displayed relative to the displacement of the measured value.
[Max] blinks when the maximum values are updated.
Tolerance judgment results are displayed with respect to the maximum value.
Tips
• In absolute measurement, it is possible to preset any maximum value and perform measurement
based on that position. Refer to "9. Measurement Method" - "2) For absolute measurement
(ABS)" for preset settings.
• If the pointer on the analog bar exceeds the display range with respect to the displacement of
the measured value, the pointer automatically returns to the center position.
● Minimum value (Min) display
The minimum value is always displayed relative to the displacement of the measured value.
[Min] blinks when the minimum values are updated.
Tolerance judgment results are displayed with respect to the minimum value.
Tips
• In absolute measurement, it is possible to preset any minimum value and perform measurement
based on that position. Refer to "9. Measurement Method" - "2) For absolute measurement
(ABS)" for preset settings.
• If the pointer on the analog bar exceeds the display range with respect to the displacement of
the measured value, the pointer automatically returns to the center position.
