1. Introduction

The digital electric micrometer is a measuring instrument with a large easy-to-see
(three-color) digital display and an automatic mastering function. It can be operated by
external input and output signals and is thus suited for automatic measurement.

2. Main Features

(1) A large three-color main digital display provides the ease of seeing judgment and

measurement results.

(2) An eight-digit multifunctional alphanumeric display indicates the measurement

conditions and items.

(3) Control keys and external signals automate mastering.

(4) Judgment result output signals are provided as standard and are ideal for automatic

measurement.

(5) The standard serial communication function allows the output of data to the personal

computer and printer. The data can be stored, statistically processed, and input to a
spreadsheet program like Excel.

(6) Two electric micrometers can be connected for measurement by operational

processing. Tapers, ovals, and steps can be measured.

3. Main Modes

The instrument operates in the following four main modes:
(1) Measure mode

Measure: Measures a work.
Hold measured value: Holds the measured value, except when the

mastering result is NG.

(2) Set mode

Enters and changes the set value.

(3) Master mode

Master: Calibrates the instrument with the masters.

This instrument is a comparative measuring
instrument. Be sure to use it upon completion of the

mastering operation.
Adjust detector: Adjusts the detector.
Clear mastering data: Clears the mastering data.

(4) Change program mode

Changes from one program to another. When the instrument is started, the
program used last is launched.

7.3.3 Procedure for calibrating instrument with masters by external input

(1) Description

Set the minimum and maximum masters in that order.

(2) Mastering

➀ Check that “READY” is displayed.
➁ Set the minimum master in the measuring head.
➂ After about 2 sec of stabilization time, input the “Minimum mastering” signal.
➃ Set the maximum master in the measuring head.
➄ After about 2 sec of stabilization time, input the “Maximum mastering” signal.
➅ Check that “MAS OK” is displayed. If “MAS OK” is displayed, the mastering

procedure is completed. If “MAS OK” is not displayed, check the setting of each
master, and adjust the measuring head and A/E converter, among other things.

7.3.4 Measuring procedure

(1) Description

In the measure mode, the instrument continues to produce the judgment result output.
In the case of static measurement, it holds the measured value display and judgment
result output when the measure command changes from off to on.

(2) Static measurement

➀ Check that “READY” is displayed.
➁ Check that “MAS OK” is displayed.
➂ Set the work in the measuring head.
➃ After about 2 sec of stabilization time, turn on the measure command. (The

measured value display and judgment result output are held, and “All OK/NG” is

output.)

➄ Read the data.
➅ Input the RESET signal. (The measured value display and judgment result output

hold is cleared.)

O: Check input signal

(3) Dynamic measurement

When “+PEAK”, “–PEAK”, “TIR”, or “TIR/2” is selected at [FUNCTION], the instrument
makes dynamic measurement. When any other item is selected, the instrument makes
static measurement.
The dynamic measurement differs from the static measurement in that the instrument
starts the measurement at the first measure command and holds the measured value at
the second measure command. When making a measurement at an external input
signal, usually set WaitTime and MeasTime both at 0 sec. Before the start of the
measurement, input the RESET signal to clear the peak value accumulation.
