SHIMPO Instruments DT-207LR-NIST User manual

DT-200LR Handheld Digital Laser Tachometer
Operation Manual

• 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 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.

Series DT-200LR Combination Contact/Non-Contact Laser Ta­chometers Laser-enabled precise RPM measurement up to 20
feet.

The Series DT-200LR digital tachometers incorporate laser

technology yet retain our hallmark rugged construction and reli­able quality components. Units offer incredible value and versa­tility as they can operate in non-contact and contact applications.
These instruments feature a field-upgradeable contact adapter for
linear rate measure, conveniently allowing both non-contact and
contact measurements.

All Series 200LR units come standard with a NIST traceable cali­bration certificate. We’re confident you’ll agree that these fine units
are the most advanced handheld tachometers on the market!

CONTROL PANEL

OPERATION

Non-Contact Measurement

1. Place a small piece of reflective tape
(included) on the shaft or moving 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.

2. Aim the tachometer at the reflective tape from a distance of 5”
(127 mm) to 20’ (6.m).

3. Press and hold the power switch for several seconds (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” the RPM indicator
will be flashing.

4. After observation is completed, retain the reading by releasing
the power switch (to turn off laser) before removing the tachome­ter from its position. The last reading is displayed for a period of 5
minutes and can be extended any number of additional 5 minute
increments by pressing the memory switch.

NOTE: When switching from the contact to the non-contact mode,
the unit RPM will show on the display and also 5 dashes (-----).
Press the power switch to cancel the dashes.

Contact Measurement

For both RPM measurements and non-RPM measurements,
screw the DT-ADP-200LR Adapter (included) into the front of the
tachometer.

NOTE: Hand tightening is sufficient; do not use excessive torque
when mounting DT-ADP-200LR Adapter

RPM Measurement

1. Place rubber cone tip on the shaft of the
DT-ADP-200LR 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 the master wheel and select the de­sired function using the selector switch locat­ed just below the LCD display (see above).

2. Press and hold the power switch; while the
wheel is turning and the tachometer is mea­suring the selected function, the function will
be indicated, and the unit of measure func­tion 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 button.

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 RECALL

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

DT-205LR:

DT-207LR:

These readings can be recalled by pressing the memory switch.
During measurements, 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 1PM),
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).

Memory Clearing
To clear the memory (for all functions), press the memory switch
for approximately 5 seconds until the display shows” CCCCCC “.
Next, press the white Power switch or Memory switch. This resets
the tachometer for use.

BATTERY REPLACEMENT (2 each “M”)

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.

TROUBLESHOOTING

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)
