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.
