1.Overview
The HR-6800 Digital Tachometer is a handy tachometer with
built-in batteries integrating the measurement unit and dis-
play unit. It is designed for measurement of bodies of revolu-
tion for dental instruments, textile machines, and general-
purpose high-speed machine tools, etc.
With the use a dedicated Detector, the HR-6800 makes it
possible to measure the rotational speed of the body of revo-
lution under measurement.
Up to 20 measurement data items can be stored in the HR-
6800 unit using the memory function, which is useful for sub-
sequent confirmation.
The display unit displays the rotational speed (x10 r/min) with
a 5-digit number.
The equipment is provided with an analog output (inter-
changeable with a monitor output) and a pulse output. The
analog output is used for recording with a data recorder, etc.,
and the pulse output for tracking analysis with an FFT ana-
lyzer.
2.Features
・Measurement from low to high rotational speeds (100 to
999,990 r/min)
・High sensitivity
・MAX and MIN modes for displaying the maximum and
minimum values
・Convenient memory function (up to 20 items can be
memorized) for confirmation of measurement results
・Over mark function for indicating measurement values
exceeding a specified value
・Analog output, sensor signal monitor output, and pulse
output
・Type AAA batteries and AC adapter commonly used
・Back light function which is convenient for use in dark
places
3.Measurement Principle
The Detector incorporates a permanent magnet and a de-
tection coil to detect the rotational speed of an object under
measurement based on the principle of electromagnetic in-
duction.

Name and Function of Each SectionObserve the Following Points before Use
CAUTION
●Do not drop the equipment or apply excessive shock to
it.
Since this equipment incorporates high-precision elec-
tronic parts, be careful not to drop it or apply strong shock.
●Wipe dirt off using a dry cloth or a cloth dampened with
neutral detergent and squeezed firmly. Do not use vola-
tile oils (thinner or benzine) or alcohols.
●Be sure to use the supplied connection cables.
Using cables other than the supplied one may make it
impossible to obtain specified performance or, in the worst
case, cause damage to the equipment.
●Measurement in strong magnetic field or near an AC line
is not possible.
Since this equipment has a high input sensitivity to en-
able measurement with a minute signal, measurement in
strong magnetic field or near an AC line is not possible.
WARNING
●Perform measurement using enough care with the target
under measurement rotating at high speeds.
Be careful not to allow connection cables to be caught by
rotating sections.
●When using an AC adapter, be sure to use a dedicated
AC adapter (option).
Using adapters other than the optional one may cause
failure.
●Avoid using the equipment in places subject to rapid tem-
perature change.
Do not move the equipment rapidly from a hot place to a
cold one or vice versa. Condensation can form inside the
unit which may cause failure.
●Be careful not to get water, oil, dust, or foreign materials
inside the unit.
Do not use the equipment in places where you may get
water or oil or places which are humid or dusty.

4.Measurement
①Connect the HR-6800 unit with the Detector using the
supplied cable.
②Select Type A or B using the Type selector switch on the
side face.
③Slide the power switch to turn the power ON.
④Set the number of pulses per rotation (P/R) and other
parameters according to the object under measurement.
⑤Bring the Detector close to the object under measurement.
Bring the end or its side face of the Detector to the body
of revolution as shown below.
【Detection at the end】
【Detection at side face of the end】
⑥During measurement, turn the trigger level adjustment
volume so that the indicator blinks stably and the rotational
speed be displayed. Since the center value of the trigger
level adjustment volume is 5, gradually increase or
decrease the trigger level from 5 to adjust the trigger level.
⑦Perform measurement.

Options Storage
The storage temperature range of the HR-6800 is -10˚C
to +50˚C. When you store it, avoid locations where the
temperature is extremely high or low or the humidity is
high. Store it in a place which is well-ventilated and not
exposed to direct sunlight. If you do not use it for a pro-
longed period of time, be sure to remove the batteries to
prevent accident caused by battery leakage, etc.

3.Measurable Bodies of Revolution
The HR-6800 enables measurement of the following bodies
of revolution:
・A body of revolution with a magnet embedded
Most stabilized measurement is possible.
This system is recommended for a drill for rotation test.
・A body of revolution partially polarized
A magnet is rubbed on a part of the body of revolution for
polarization before measurement. If the magnetic force
weakens with time, polarization is performed again.
・A body of revolution with a bumpy shape
Since a magnet is embedded in the Detector of the HR-
6800, whether a body of revolution can be measured
depends on its shape. However, depending on the material
and shape of the body of revolution, a detected signal may
become minute making detection of rotation difficult.
Therefore, if possible, magnet-based detection is
recommended.
Note: Since the Detector has frequency characteristics,
it needs strong magnetic force particularly when
measuring low rotational speed.
Refer to the following rough standard of magnetic
force:
100 r/min: 10 mT or more
10000 r/min: 5 mT or more
100000 r/min: 1 mT or more
Note: Measurement is not possible in places where
strong magnetic field is present around the mea-
suring point.
