1-2. Features
Peak Hold Function Convenient for Statistical Measurement
It can be set to hold maximum, minimum and peak-to-peak values in counting.
Convenient External Input Functions for Automatic Measurement
In addition to external reset and external preset value call functions, general-purpose inputs are available in the external interface for operations useful for automatic measurement. (The general-purpose inputs can be used as various signal inputs according to the advanced settings.)
BCD Output (Option)
When BCD unit (LZ71-B) is combinedly used, a vatiry of data can be read out via BCD output.
(Current value, maximum value, minimum value, peak-to-peak value)
Comparator Function suitable for in-line measurement applications.
When comparator unit (LZ71-KR) is combinedly used, current values are taken into comparison with comparator setting values and results are output and indicated on the display panel as well. (The comparator output can be either rely or open-collector)
The output signals of comparison results can be used for applications such as part-sorting in in-line measurement and positioning on grinder machines.
The comparator is capable of maximum 16 sets of setting values, each set consisting of 1 to 4 points. Various
Switches can be carried out with both front keys and external input interface.
Display Resolution Switching
The display resolution can be selected from the following.
Linear : 0.1
µm to 10 µm
Angles : 1 second to 10 minutes
(Choose the appropriate setting for the connected measuring unit.)
Data Storage
Displayed data and preset data are stored automatically.
Therefore, data can be easily relocated even after the power is turned off or in case of a temporary power failure. (You can select whether to use held values.)
Preset
Each axis can have up to three preset values.
This is useful when setting multiple preset values.
Detecting Reference Point of Measurement Unit
When connected measuring units with build-in reference points, reference points can be detected whenever needed and used as absolute reference points in measurement.
Scaling
The counter can be set to display actual measurement by any multiplier, either scaling-up or scaling-down, within the setting range.
This function is especially helpful in handling contract in materials such as resin and so on when making dies by converting product dimensions to die ones.
Flicker Control
Flicker on the least significant digital caused by connected higher resolution measuring units or vibration from machine tools on which measuring units are installed can be easied by enabling flicker control function.

4-3-4. Scaling
This changes the display dimension magnification. This is mainly used when measuring objects with different reduced scales or when taking die shrinkage into account for cutting.
Example 1. When measuring a 1/2 model as an equal magnification model
By setting 2.000000, the display changes by 2 mm for each 1 mm of movement.
Example 2. When cutting a die for a resin part with a resin molding shrinkage ratio of
0.95%
A large die is cut in consideration of shrinkage, so the die dimension relative to the part dimension is 1/0.95. Therefore, a die can be cut with the part dimensions as is by setting
1.052631.
4-3-5. Linear compensation
Unlike gauge-type measuring units, scale-type measuring units experience dimensional error caused by sagging of the device to which the scale is attached. You can compensate this sagging by measuring the compensation value as outlined in “2-19-2 Linear compensation” of the Operating Manual, and setting that value.
4-3-6. Hold function
The hold function consists of a latch function and a pause function.
Latch : You can hold the display even while the measuring unit is moving. This is used to read the dimension at a particular point without stopping movement during measurement.
Pause : You can pause updating of the peak value calculation even while the measuring unit is moving. Data resulting from movement while paused is not reflected to the peak value calculation.
4-3-7. General-purpose input
You can perform operations by external contact point input instead of key operations.

Overview of external contact point inputs
Input circuit for external input signals
• When using external input, connect the signal to the external input terminal for 10 ms or more (common terminal). When inputting an external signal again, ensure an OFF time of 70 ms or more.
• Use a shielded cable for the connecting cable, and connect the shielding to the I/O connector shell. In addition, connect COM separately from the shielding. (The switches and shielded cable should be prepared separately by the customer.)

Input circuit delay time
When an input signal is input, the input circuit causes a delay time until that signal is transmitted to the internal circuits. Note that this delay time differs greatly according to the input circuit operating voltage.
(Example) When operated at
+24 V, the delay time until the signal is transmitted to the internal circuits is approximately 350 µs.
The process time after the signal is transmitted to the internal circuits until operation is actually performed differs according to the operating conditions. When not using expansion units, this takes at least 5 ms (min.).
This time becomes longer when expansion units are connected.
The delay time is greatly reduced by not connecting portion q in the “Input circuit for general-purpose input, external reset and external preset value call (preset recall)” circuit drawing above. However, in this case noise or other factors can easily cause misoperation. Therefore, be sure to take noise countermeasures when not connecting portion q.
When q is not connected
When using
+24 V, the delay time is approximately 3 µs.

4-3-10. Current value store
This sets whether to display the previous value when the power is turned on again.
When using the master calibration function, a value is not displayed unless the measuring unit goes past a reference point, and so it will not function even if set to ON.
4-3-11. Flicker control
If the number for the minimum digit of the display value is flickering and unstable, this flickering can be reduced.
Because the flicker control is realized by averaging measured valves, enabling flicker control could possibly affect the display response to some extent.
When using the LZ71-B, updating of the BCD output data may be delayed and the same data may be repeatedly output depending on the acquisition timing. If this occurs, use with the flicker control function set to OFF.
