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.

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 I of 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

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.

14. Maintenance
(1) The air filter is clogged as it is used for a long period of time. Change the air filter
element after two years of use or when the pressure drop reaches 0.1 MPa.
(2) Cleaning A/E converter
When the A/E converter is used for a long period of time, oil and dust may
accumulate in the air circuit. Clean the A/E converter as described below.
Record the approximate installation position of the zero and sensitivity adjustment
knobs at the front of the instrument (or the distance of each knob from the edge).
This record facilitates mastering after cleaning.
Turn the zero and sensitivity adjustment knobs counterclockwise, and remove
them from the instrument.
Check the O-ring of each needle. If the O-ring is damaged, change it.
If the needle is dirty, clean it. Dampen a cotton swab with alcohol, and use it to
clean the φ3 mm hole into which the needle enters.
Replace the needle in each knob. If the split screw is loose, expand it with the tip
of a flat-end screwdriver. Take care not to overbend the split screw.
Turn the needle of each knob clockwise, and install the knobs in the original
position recorded at first. Adjust the zero position and sensitivity of the air circuit
with the zero and sensitivity adjustment knobs, respectively, and calibrate the
instrument with the minimum and maximum masters.

16. Cautions
(1) Air supply
Supply clean air free from dust, moisture, and oil. Drain the air filter once per day or
more frequently.
(2) Power cable
The power cable supplied as standard accessory is for 100 V. If you use supply
voltage in excess of 125 V, separately prepare a 250-V power cable.
(3) Control keys
Never operate the control keys with a sharp-pointed tool or the like.
(4) Export
When you try to export this instrument overseas, you may have to have the export
approved by the Ministry of Economy, Trade and Industry under the Export Trade
Control Ordinance. In such a case, contact your nearest NIDEC TOSOK sales
office.
(5) Specifications
The specifications are subject to change without notice.
