SHIMPO Instruments MT-200 User manual

MT-200 Combination Contact/Non-Contact Pocket Tachometer

Operation Manual

Laser radiation may be harmful to the human eye. Avoid direct exposure
of human eyes to laser light. Eye damage can result.

Never point the unit at another person.

Keep out of the reach of children.

Avoid indirect exposure via reflective materials such as glass and
mirrors.

When power button is depressed, laser is active.

When using the master wheel, do not use an extension shaft as
the wheel may come off of the shaft and cause damage or injury.

Although the tachometer is able to achieve higher measurements than
what is listed, the master wheel has a maximum speed limitation of 5000
ft/min (for safety reasons).

The MT-200 Combination Contact/Non-Contact Pocket Tachom­eter

with microprocessor technology possesses the precision

of the standard Shimpo Tachometer line, yet within a compact,
pocket-style enclosure.These battery-operated tachometers fea­ture the same rugged, high quality components that have made
Shimpo tachometers the benchmark in the industry. The MT-200
provides users with the capabilities of measuring and recording
speeds of rotational, linear and surface plus total length in both
contact or non-contact modes. The user-friendly, value-packed
units feature memory storage; quick selection unit’s button; length
functions; retrieval of last, maximum and minimum values; plus
each unit comes standard with a free N.I.S.T. calibration certifi­cate. Each unit ships in a protective carrying case which includes
a cone adapter, funnel adapter and 6” circumference wheel.

OPERATION

Non-Contact Measurements

Measuring revolutions per minute or total revolutions.

1. Attach a piece of reflective tape on the object to be
measured.

NOTE: Accurate measurement may not be achieved if the rotating
object to be measured is shiny. Cover with black tape or paint
then attach the reflective tape.

Measuring surface speed and distance using the 6” circumfer­ence wheel.

1. Attach the contact adapter to the tachometer. Do not over tight­en.

2. Attach the 6” circumference wheel to the tachometer by placing
the wheel on the adapter shaft. Align the shaft pin with the notch
of the wheel stem.

2. Press the POWER button to turn the tachometer on.

3. Select RPM (revolutions per minute) or REV (total number of
revolutions) by pressing the UNIT button.

4. Aim the laser beam at the reflective tape.

5. Press and hold down the POWER button to start measuring.

6. Press and hold the POWER button to take another
measurement.

Laser - Do not look into the beam. Use protective
eyeglasses that are rated for 670usec for adequate
eye protection.

Contact Measurements

Measuring rotation speed using the cone or funnel-shaped
contact probe.

1. Attach the contact adapter to the tachometer. Do not over tight­en.

2. Attach the cone or funnel adapter to the tachometer by plac­ing on the adapter shaft. Align the shaft pin with the notch of the
adapter stem.

3. Press the POWER button to turn the tachometer on.

4. Select RPM (revolutions per minute) or REV (total number of
revolutions) by pressing the UNIT button.

5. Press and hold the POWER button to start measuring.

6. Bring the contact probe into contact with the object to be mea­sured by touching the contact probe slowly to the center of the
rotating object. If the measuring range of the tachometer is ex­ceeded, “OVR” will appear on the tachometer’s display.

7. Press and hold the POWER button to take another measure­ment.

8. Press the UNIT button to convert between ranges. When a
high-speed rotating object is measured for hours using a cone or
funnel adapter the surface of the adapter may become very hot.

When a high-speed rotating object is measured
for hours using a cone or funnel adapter the
surface of the adapter may become very hot.

6” Circumference Wheel Dimensions

1.91”

(48.5 mm)

3. Press the POWER button to turn the tachometer on.

4. Select meters/minute (m/M), yards/minute (Y/M), inches/min­ute (I/M), feet/minute (F/M), meters (m), yards (YRd), feet (FT), or
inch (IN) depending on which units you wish to measure.

5. Bring the 6” circumference wheel into contact with the object to
be measured by slowly touching the wheel to the moving object.

6. Press and hold the POWER button to start measuring.

7. Press the UNIT button to convert between ranges. When mak­ing surface speed or distance measurements, ensure that the 6”
circumference wheel’s perimeter is parallel to the object to be
measured.

When making surface speed or distance
measurements, ensure that the 6” circumference
wheel’s perimeter is parallel to the object to be
measured.

NOTE: When using the master wheel, accuracy can be affected
as much as 0.3% of reading.

Memory Function

The tachometer’s memory capabilities are as follows:

1. Minimum, maximum and last measurements are recorded au­tomatically by the tachometer.

2. Ten selectable measurements can be programmed into mem­ory by pressing the MEM button while the POWER button is fully
depressed (M1, M2, M3, … M10).

Battery Replacement

When “LO BAT” flashes on the display, install new batteries.
To replace the batteries:

1. Slide open the battery cover (located on the rear of the tachom­eter).

2. Remove old batteries and insert three fresh AA size batteries,
observing proper polarity. Do not mix old and new batteries.

3. The average value of sequentially stored memory, up to ten,
can be viewed by pressing the MEM button.

NOTE: If the memory button (MEM) is not selected while the
POWER button is pressed the measurement will not be recorded
into its memory location, The memory will be recorded automati­cally into memory if the measurement made is the maximum, min­imum or last measurement.

To delete stored memories do one of the following:

1. Press the MEM button for five seconds or more. All memory will
be erased after [CCCCC] is displayed.

2. Changing the units of measurements and then making addi­tional measurements.

3. Memory will be automatically erased if the tachometer turns off
automatically after five minutes.

3. Slide the battery cover back into place.

TROUBLESHOOTING

No laser beam is evident:

• Confirm that the POWER button is operating properly.

• Confirm that the batteries are functioning properly and that they
are inserted into the tachometer with correct polarity.

Inaccurate measurement results:

• If the surface being measured is highly reflective, it may need to
be painted darker to ensure that the tachometer can distinguish
between the reflective tape and the background.

• The laser beam may not be hitting the reflective tape, or the
taped area may be too small.

• Measuring distance may be to short. The minimum distance for
non-contact measurements is 12.7cm
