2 Operations and Functions during Measurement

Setting the Display Value Instantaneously

to Zero (Auto-Zero)

This section describes the auto-zero function, which is used for referencing

zero-point position.

Operation of the key or others resets the present displayed value to "

0.0000

". By

considering this zero position as a reference, the increase and decrease are displayed in ±

(positive/negative). This function can be used for reference zero-point positioning when a

workpiece is changed.

The example below uses the auto-zero function by using the 150-µm target as a reference.

Auto-zero cannot be set at comparator standby state (displayed as "------") and over-

range state. However, cancellation of auto-zero is possible.

• The auto-zero value is stored according to program No. and OUT.

• The auto-zero value is retained even if the power is turned off.

• When the measurement mode is other than normal, the comparator standby state ("---

---") is established after auto-zero is set.

• Adjusting a master workpiece by using the offset function (auto offset function)

When the offset value is set to the size of the master workpiece, enabling the auto-zero

will set the numerical value to the size of the master workpiece (offset value).

• Auto-zero is set for the measurement value that underwent a measurement mode

process ( page 3-25).

Refer to "Measuring with Offset" (page 3-32).
