① Power switch
Used to set the power ON/OFF.
② Display
Displays measurement values and settings.
③ Input connector
Connector for connecting sensors.
④ RECALL/↑ switch
In setup mode, this switch is used to enter numeric
values or change selections.
For acceleration/deceleration rotation measurement
(when algorithm E of "ACt" mode is selected) in
measurement mode, this switch is used to select
the rotational speed at the measurement start from
sampled candidate values.
⑤ MENU switch
Used to switch over between measurement and
parameter setup modes.
⑥ SAMPLE/→ switch
In setup mode, this switch is used for digit shifting.
Before starting acceleration/deceleration rotation
measurement (when "ACt" mode is selected) in
measurement mode, this switch is used to calculate
rotational speed candidate values for the measure-
ment start by sampling rotational speed data.
⑦ MODE/NEXT switch
For acceleration/deceleration rotation measurement
(when algorithm E of "ACt" mode is selected), this
switch is used to determine the candidate value
selected with the
④
RECALL switch as the rota-
tional speed at the measurement start.
⑧ Indicator (input signal check light)
When the amplifier sensitivity is appropriately set
for the sensor signal amplitude, this indicator blinks
cyclically.
This indicator is off when no sensor signal is input
or the amplifier sensitivity is insufficient.
It is lit when the amplifier sensitivity is excessive.
⑨ Sensor selection switch
This switch is used to switch between IP Series and
other sensors.
⑩ Sensor amplifier sensitivity adjustment dial
Dial for adjusting the sensor amplifier sensitivity.
⑪ Tripod mounting hole
Tapped hole for mounting tripod
⑫ Battery cover
⑬ Connector cover
Cover of DC power input and output connectors
⑭ DC power input
Input connector for connecting dedicated AC
adapter (When the dedicated AC adapter and bat-
teries are both used, the AC adapter is used in
priority.)
⑮ ANALOG output
Connector for connecting optional AX - 501 cord of
recorder, etc.
⑯ PULSE output
Connector for connecting optional AX-501 cord for
outputting pulse converted from power spectrum
frequency
⑰ CONDITION display
Displays low battery level or an error.
⑱ MAIN display
Displays measurement values, selected contents,
set values, etc.
⑲ SUB-display
Displays set items, etc.
⑳ UNIT display
Displays measurement unit (r/min).
Be Sure to Read Before Starting Operation
● Be careful about rotating parts of an engine, motor,
etc. during measurement.
When using an optional detector and/or AC
adapter, take care not to let the cables be rolled
into the rotating part of the engine.
WARNING
CAUTION
● Be careful about hot parts of an engine, motor, etc.
during measurement.
CAUTION
● Do not let this product touch hot parts of an
engine, motor, etc.
This product is not heat-resistant. So, be careful not
to let it touch hot parts (exhaust pipe, etc.).
● Do not let this product touch an ignition coil.
Doing so may cause malfunction or failures.
● Accurate measurement may be disabled for an
engine with faulty ignition system (distributer, high-
tension cable, ignition plug, etc.).
● Be sure to use the dedicated AC adapter (optional),
when necessary.
Using other adapters may cause failures.
● When installing dry cell batteries in the product,
take care of polarities.
If dry cell batteries are installed in wrong direction,
the fuse may blow.
● Avoid rapid temperature change.
Do not move the product from a hot to cold place,
or vice versa, in a short period of time. Dew con-
densation inside the device may cause failures.
● Prevent foreign substances such as water, oil, dust
from getting into the device.
Do not use the device in a place where it may get
wet or oily or in environment subject to moisture or
dust.
● Be careful not to let it fall or give strong vibration or
shock to it.
This product contains precision electronic parts. Be
careful not to let it fall or give strong vibration or
shock to it.
● If the product is contaminated, wipe it with dry cloth
or cloth dipped in solution of neutral detergent and
tightly squeezed. Do not use volatile oil such as thin-
ner or benzine or alcohol.
