TURES AND BENEFITSTURES AND BENEFITS

The Shimpo DT-207L is a battery-operated, microprocessor­controlled, non-contact/contact tachometer that utilizes a laser
beam for movement detection. In the non-contact mode a laser
beam measures RPM when directed towards a shaft (or any other
rotating mechanism marked with a small piece of reflective tape).
The included 200L adapter allows for contact measurement via
a rubber tip cone attachment or the included wheel attachment.

The DT-207L tachometer incorporates the latest microprocessor
and laser technology and offers:

• Multi-mode capability measures RPM, mPM, YPM, FPM, IPM
and total meters, yards, feet and inches

• Large memory capacity allows up to 13 measurements to
be stored in memory

• Single chip microprocessor ensures reliability and low
maintenance

• Safely measures RPM (non-contact mode) from up to 14
feet away

• 5-digit LED display permits easy reading

Congratulations on your purchase of a Shimpo DT-207L digital
laser tachometer! We trust you will enjoy many years of
professional results from your Shimpo tachometer.

Please read the entire instruction manual thoroughly before
initial set-up and operation; the information contained herein
will aid you in operating your Shimpo tachometer safely and
with excellent results.

If you have any questions regarding our product(s), call your
local Shimpo representative or contact Shimpo Instruments
directly for assistance.

ANT SAFETY INSTRUCTIONS

ANT SAFETY INSTRUCTIONSANT SAFETY INSTRUCTIONS

When using the 6" wheel, do not use the extension
shaft - the wheel may fly off the shaft and cause
damage.

Although the tachometer alone is able to achieve
the higher ranges listed in the Range and Accuracy
table on page 3, the wheel attachment has a
maximum speed limitation of 5,000 FPM (for safety
reasons).

Laser Use and Safety

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.

Non-Contact Measurement

1. Place a small piece of reflective tape

2. Aim the tachometer at the reflective tape from a distance

3. Press and hold the power switch for several seconds

4. After observation is completed, retain the reading by

NOTE: When switching from the contact to the non-contact mode,

Press the power s witch to cancel the dashes.

Contact Measurement

For both RPM measurements and non-RPM
measurements, screw the 200L adapter
(included) into the front of the tachometer.

NOTE: Hand tightening is sufficient; do not
use excessive torque when mounting

RPM Measurement

1. Place rubber cone tip on the shaft of

element (disc, pulley, etc.) whose
speed is to be measured. If the
element's surface is highly reflective
it may need to be painted a darker
color in order to ensure reliable
results. If the distance to the object
is less than 5" (127 mm), reflective tabs (optional) should
be used instead of reflective tape.

(when power button is depressed, laser is
active) to observe the display as it changes according
to the speed of the shaft or rotating element (as soon as
the laser hits the reflective tape, the unit will start to
indicate the speed). If the beam is “on target” a red dot
will flash in the upper right corner of the display. If the
red dot is not flashing, the beam is "off target", and the
aim needs to be adjusted.

removing the tachometer from its position. The last
reading is displayed for a period of 10 seconds and can
be extended any number of additional 5 minute
increments by pressing the memory switch.

the 200L adapter. Make certain that
the pin on the shaft is properly
aligned with the slot on the cone’s
sleeve.

2. Bring cone into contact with the shaft. Apply only enough
pressure to avoid slippage.

3. Press and hold the power switch. During engagement
the display will reflect the proper RPM while the unit RPM
will be flashing above the display digits.

4. Release the power switch prior to removal of tachometer
from rotating object to capture the last reading.

5. After release of the power switch, the last reading (with
a non-flashing RPM unit) will remain on the display and
in memory for 5 minutes, and can be extended any
number of additional 5 minute periods by pressing the
memory switch.

Rate & Length Measurement

1. Attach 6" master wheel and select the
desired function using the selector
switch located just below the LED
display.

2. Press and hold the power switch;
while the wheel is turning and the
tachometer is measuring the selected
function, the red dot in the upper
right corner of the display will be flashing.

3. Release the power switch before disengaging the
tachometer in order to capture the last reading.

4. After release of the power switch, the last, maximum,
and minimum readings will be stored in memory for 5
minutes and can be extended any number of additional
5 minute periods by pressing the memory switch.

NOTE: The memory will clear in 5 minutes after the release of
the power switch.

For steps 1-4 described above, it was assumed that the selector
switch was in the rate mode region. If the selector switch is
moved from the rate mode to the count mode (length), the
display will show the selected function (m, ft, yd, or in) and also
5 dashes (-----). Press the power switch to cancel the dashes
and start measuring the same way as was described above. Once
in the counting mode, the measurement can be stopped at any
time and the last reading will be retained for 5 minutes. There is
no maximum or minimum reading when in the count (length)
mode.

MEMORY RECALLMEMORY RECALL

MEMORY RECALL

MEMORY RECALLMEMORY RECALL

The following readings are stored in memory for 5 minutes
after release of the power switch:

• Memory reading

L

• Last reading

M

• Maximum reading

• Minimum reading

These readings can be recalled by pressing the memory switch.
Ten extra readings can also be captured, stored, then recalled
using the memory switch. While the tachometer is in use,

simply press the memory switch each time a reading
needs to be stored.

Contact Mode (Rate Functions)

When the rate functions are selected (mPM, YPM, FPM and
IPM), the memory store and recall functions are accomplished
exactly as noted above.

Contact Mode (Length Functions)

When the counting functions are selected, the memory store
and recall functions are accomplished in the same manner as
the non-contact mode, the only exception being the maximum
and minimum readings (they do not exist).

To clear the memory completely (for all functions), press the
memory switch for approximately 6 seconds until the display
shows CCCCC, then release the switch.

Low battery voltage is indicated by flashing LOW BAT on the
display. Remove end cover by using a coin or appropriate
screwdriver and replace both batteries. Please ensure proper
polarity.

NOTE: When using the 6" master wheel, accuracy can be
affected as much as 0.3% of reading

Although the tachometer alone is able to achieve
the above ranges, the master wheel has maximum
speed limitation of 5,000 FPM (for safety reasons)

The following are general checkpoints; please call your local Shimpo representative or contact Shimpo Instruments directly
for further assistance.

No laser beam is evident:

• Confirm that power switch is functioning

• Confirm that batteries are functioning and that polarity is correct

Inaccurate measurement results:

• If the surface being measured is highly reflective, it may need to be painted a darker color in order to ensure reliable results

• Beam may not be hitting the reflective tape, or taped area may be too small

• Measuring distance may be too short (unit must be at least 5” from intended mark)
