Congratulations on your purchase of a Shimpo DT-205L 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.
Inspection/Standard Accessories
If upon delivery shipping damage is detected, do not operate tachometer. Notify shipping carrier immediately for damage claim instructions. Refer to nameplate and record serial number for future reference.
Items included with the DT-205L are:
•Carrying case
•Cone adapter
•200L adapter
•6” master wheel
•Reflective tape
The Shimpo DT-205L 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 6” master linear wheel.
The DT-205L 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
•Oversized 5-digit LCD display permits easy reading
•Long battery life (up to 40 hours of continuous use)
•Rugged die-cast aluminum housing provides exceptional durability
•Extended measuring range (6 - 99,999 rpm) covers wide range of applications
Important Safety Instructions
Do not point the laser beam into eyes as permanent eye damage may occur! Shimpo Instruments does not condone usage inconsistent with product's labeling and warning.
When using the 6” master 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 master wheel has a maximum speed limitation of 5,000 FPM (for safety reasons).

Operating Procedures
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 14' (4.3 m).
3.Press and hold the power switch for several seconds 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 unit RPM will flash at the top of the display. If RPM is not flashing then the beam is “off target” (adjust aim).
4.After observation is completed, retain the reading by releasing the power switch 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 nonRPM measurements, screw the 200L adapter (included) into the front of the tachometer.
NOTE: Do not use excessive torque when mounting - hand tightening is sufficient
RPM Measurement
1. Place rubber cone tip on the shaft of 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 the 6” master wheel and select the desired function using the selector switch located just below the display.
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 above the digits and 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.
