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.

2
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.

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.

6. Measurement
6.1 Preparation
Attach the regulator to the rear of the instrument, and connect it with the air filter.
Connect the measuring nozzle hose to the front of the instrument, and connect the
accessory power cable to the rear of the instrument.
Turn on the power switch (or press the position marked Iof the switch) at the rear of
the instrument, so that the power of 85 to 264 VAC (50/60 Hz) will be supplied to the
instrument. Supply air at 0.3 to 0.7 MPa to the air filter.
When the instrument is started, it is in the measure mode. Press for 2 sec to
change to the master mode, for 2 sec to change to the set mode, and for 2
sec to change to the change program mode.
6.2 Measuring
Bargraph display, and item and judgment LEDs
(1) The judgment upper and lower limit values are indicated by orange (dark) on the
bargraph display.
(2) The bargraph display is illuminated green (light) and red (light) when the judgment
result is OK and NG, respectively.
(3) The item and judgment LEDs 1, 2 and 3 come on red, green and red when the
measured value is –NG, OK and +NG, respectively.

Hold measured value mode
The measured value is held, except when the mastering result is NG.
(1) The bargraph display is usually in the measure mode and shows the value being
measured (this is called the free run condition). In the free run condition, the
measured value is indicated by green (light) on the bargraph display when it is OK
and by red (light) on the bargraph display when it is NG.
(2) Press in the free run condition to hold the measured value (this is called the
hold condition). In the hold condition, the measured value is indicated by green
(dark) on the bargraph display when it is OK and by red (dark) on the bargraph
display when it is NG.
(3) Press to clear the measured value hold.

If there is a mastering error, its description is shown on the alphanumeric display as
follows:
ERR ZERO: Zero position error (outside of automatic mastering range)
ERR MAG: Sensitivity error (outside of automatic mastering range)
ERR REV: Maximum and minimum master values reversed
ERR OFFR: Outside of measuring range
Press to return to step above. If it is necessary to adjust the zero position
and sensitivity of the air circuit with the zero and sensitivity adjustment knobs,
respectively, refer to “10. Adjusting Zero Position and Sensitivity with Zero and
Sensitivity Adjustment Knobs”.
In the middle of the master mode, press to return to the previous condition.
When “MIN M.” is displayed, press to return to the measure mode.
Mastering data storing function
The instrument is designed to read the last mastering data and fall in the master request
condition.

Flashing of MAS LED
The MAS LED flashes orange to indicate that the last mastering data is effective
for the currently selected program and flashes red to indicate that the last
mastering data is not effective for the currently selected program (or the mastering
data is cleared).
Indication on alphanumeric display
“MAS REQ” is shown on the alphanumeric display.
Judgment result output signal (when judgment result output option is added)
The judgment result output signal “MAS OK” is turned off.

(2) Procedure for coping with master request condition
Calibrate the instrument with the masters.
When the MAS LED is flashing orange, the mastering operation can be omitted by
any of steps to below.
Press one of the control keys.
Input a reset command from an external signal or with an external button.
Input a clear master request command through the serial communication
(RS232C). (Refer to “11.1 Serial output”.)
