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 Section
Observe 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.
