Precautions
Please read this Operation Manual including the following precautions carefully to ensure safe
use of your meter.
！ ＜Caution＞ Do not use this product for applications outside of the product specifications.
！ ＜Caution＞ User-conducted alterations and modifications of the unit should not be
performed as they may impair functioning or cause failure and accidents.
！ ＜Caution＞ Direct sunshine is avoided, and ratings are used in the place of each Onshime
and the place where the be dewy occurs easily. Do not do.
！ ＜Caution＞ Do not use it in the place with the combustible gas and the ignition thing.
！ ＜Caution＞ Do not subject the unit to strong vibrations or shocks.
！ ＜Caution＞ Do not allow metallic debris, dust, or moisture to penetrate the unit.
！ ＜Caution＞ For safety, professional wiring electrical work, such as electrical wiring is please
go. Please shut off the power when electrical wiring.
！ ＜Caution＞
Please use one which matches rating for the AC/DC power supply supplied to a meter.
！ ＜Caution＞ After the power supply, it operates at once because there is no power on/off
switch for the unit.
！ ＜Caution＞ Do not touch the terminal while operating. It gets an electric shock.
！ ＜Caution＞ Wipe it with a dry cloth when you clean the meter.
！ ＜Caution＞ Devices to be connected to each terminal of the terminal block,
use the one that is properly isolated from hazardous live parts.
！ ＜Caution＞ Since there is no power switch in this machine, it will be in an operating state
immediately after power supply impression. Equipment to be incorporated in
the side of our customers,please be prepared to supply the switch and
circuit breaker which adapted to IEC/EN60947-1 or IEC/EN60947-3
standard in the position that you can operate immediately in emergency.
Moreover, please specify that they are interrupting devices.
！ ＜Caution＞ This machine is designed to be used with the panel mounted.
When used in a state other than that, there is a possibility that the
protective device is provided with is impaired.
！ ＜Caution＞ Use the temperature rating 70 ℃ or more power cord.
Product Description
This product is a panel mount meter that can measure Speed／Rotation／Flow rate／Ratio
／Shot speed／Street time／Cycle timer／Stopwatch.
The preset output function of two points has been equipped normally. The preset output
two points and the analogue signal and the BCD signal outputs can be added in the option.
The option to which the preset setting value can be input from the outside by the BCD signal
is prepared.
With the panel mounted, the front has been protected by grade IP66, dust and water
resistant products.
