1. Introduction
The column type air micrometer is a measuring instrument with an easy-to-see three-
color bargraph display. Combination with an air/electric (A/E) converter provides this
compact instrument with an automatic mastering function. It can also be easily
connected with another or more identical units to allow the trend of works to be read from
the bargraph displays arranged side by side.
2. Main Features
(1) A three-color bargraph display allows the measurement result to be more easily
seen.
(2) An eight-digit alphanumeric display indicates the measured value, set item, and other
types of information.
(3) Control keys are used to automatically calibrate the instrument with the maximum
and minimum masters.
(4) The instrument is only 50 mm wide, so that it is suited for measuring with another or
more identical units operating together.
(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) In the set mode, the ENT key can be pressed to sequentially select all items.
(7) Programs can be selected to store ten types of set values and mastering data and
change from one type to another.

3. Main Modes
The instrument operates in the following four main modes:
(1) Measure mode
Measure (in free run condition): 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.

4. Names and Functions of Controls and Parts
(1) Bargraph display
Indicates the measured value, judgment result, or other
types of information by a 101-dot, 3-color bar.

(3) Alphanumeric display
Indicates the measured value, set value, set item, or other
types of information by 8-digit 7 ×5 dot characters.
(4) Sensitivity adjustment knob
Adjusts the sensitivity of the air circuit. This adjustment is
necessary only for changing the measuring nozzle and
correcting a mastering error.
(5) Zero adjustment knob
Adjusts the zero position of the air circuit. This adjustment
is necessary only for changing the measuring nozzle and
correcting a mastering error.
(6) Measuring nozzle port
Accepts the vinyl hose of the measuring nozzle.
(7) Item and judgment LEDs
Indicate the judgment result. LED 1 comes on red when the
measured value is –NG, LED 2 comes on green when the
measured value is OK, and LED 3 comes on red when the
measured value is +NG.
Table 4-3. LED colors and conditions indicated.
