●●●● Do not use the AC power adapter except the optional AC-1046.
Other type of adapter may cause damage to the instrument.
●●●● Do not touch the plug of AC adapter (AC-1046) with wet hands. It causes shock hazard.
Stop using the instrument, when an object or liquid falls/spills into the instrument. It causes fire or shock hazard. Turn off the POWER switch and unplug AC adapter (optional) from outlet as soon as possible. To reduce risk of injury, take it to a qualified serviceman when service or repair is required. Please contact us or the dealer when service or repair is required.
3．．．．Cautions for usage
To prevent bodily injury or damage to the instrument, the following cautions must be observed.
！！！！ CAUTION
● Keep the instrument away from the children. If the instrument falls down, it is very dangerous.
●●●● Do not place it on an unstable place (shaky table or sloping place). If the instrument falls down, it is very dangerous.
●●●● Do not use and storage the place which moisture or dust, and where a bad influence place which salt, sulfur, chemicals, Gas etc.. It causes fire or shock hazard.
●●●● Do not put heavy objects on the instrument. It causes damage to the instrument.
●●●● Connect cable properly, it is instructed in this manual. Wrong connection causes fire
hazard.
●●●● Connect cable properly, it is instructed in this manual. Wrong connection causes fire hazard.
●●●● Before you move the instrument to other place, turn off the POWER switch and remove all
wiring.
●●●● Do not put the instrument on the vibrating place. If the instrument falls down, it is very
dangerous.
●●●● For avoiding liquid spill, remove alkaline dry batteries when you don’t use for long period of
time. It is recommended to remove alkaline dry batteries after each use.
●●●● Please be sure undergo periodic inspection main body and pickup 1 or 2 times in an year.
(Second calibration Sensitivity is Charge)
●●●● Please don’t push a liquid crystal display screen with a finger or a pen. It become the cause
of defective display or malfunction.
●●●● The connection connector of a main body and a curl cable is an one-touch type BNC connector. Please don’t turn a part of connector at time connection or after connection. It become the cause of failure or malfunction.
●●●●
A magnet is very powerful
and attaching to a measurement subject. Moreover, what is influenced of magnetic should release a magnetic card etc. enough. It may destroy and break down.
●●●● If it break down, please contact us to a store or an agency, without adding a hand.
(adsorptive power 100N). Be fully careful not injured, when detaching

Overview
Vibration Meter “MODEL4200” is super mine-size like a cellular phone. It offers, just like a “machinery doctor”, high precision monitoring of various industrial machinery by using the optional headphone or auscultation stick It offers a simple way of making medical chart for your machine The “data hold” function has highly promoted the easy observation of the numerical data In addition, maintenance or examination of the existing machine, or experiment for a new facility under development, has been greatly promoted by fixing and numbering the measuring points on a large-scale target machinery, or by improving the mobility of the measurement based on the “single point” scheme stated above
Features
● Vibration can be actually heard with your own ear, aiming at the pinpoint spot in question This is the time of the maintenance of facilities, by watching, hearing and measuring the vibration
● Compact design, light weight i.e., approx.130 g (Including batteries), that demonstrates power on the site of the measurement
● Single hand operation is possible just like a cellular phone
● Built in Memory for max.256 data.
● Built-in serial interface, enabling rapid data processing on your PC
● Restart the measurement with the last condition set up and stored just before the power-off
● The output to an exclusive printer is possible.
●●●● Energy-saving design allows continuous measurement longer the 12 hours straight with only 4 dry battery cells, LR03.
Guarantee
Term for guarantee is twelve months after delivery. Within this term repair is provided for free should a fault occur while the apparatus is being used in the manner prescribed by the manufacturer. Otherwise, a repair fee will be charged.

It operates by two alkaline dry cells type LR03 or AC adapter AC-1046 (option).
Battery installation
When the unit is in operation, turn off the power by pressing the Power
１）Slide the battery cover of the back to the lower direction while pressing down on the cover.
To a direction with aggressiveness
３）Insert two AAA dry cell batteries in the direction indicated in the battery case and close the

！！！！ CAUTION
● Please be sure to remove a dry cell AAA, when there is no schedule used for a week or more.
It may become the cause of failure by liquid leak.
● Please put in correctly polar "+" and "－" of a dry cell not to mistake.
● Moreover, please put in the new dry cell of the kind with four [ same ] at the time of

Attachment of an acceleration pickup
There are some methods of attachment to the measurement subject of Accelerometer.
Contact resonance frequency * changes with the attachment methods of an Accelerometer sharply. Please perform suitable attachment in consideration of the advantage and fault of each attachment method
*Contact resonant frequency and the high region characteristic
If an Accelerometer is attached in a measurement subject, one vibration system will be formed and the peculiar resonance frequency of the system will be decided. This is called contact resonance frequency. Contact resonant frequency is boiled variously and changes with the fixed method of Accelerometer and measurement subject, or contact states. A lower figure shows change of the high region characteristic by the attachment method. Therefore, the suitable attachment method of Accelerometer is chosen, and in order to remove the influence of Contact resonant frequency further, it is necessary to choose the frequency range.

0.4a～1.6a Attachment screw M6、P=1
Please make 0.4a-1.6a to the surface of an attachment side. Please fasten the bolting torque with an Accelerometer, an attachment screw, and a measurement subject by 1 - 1.5 N-m. Accelerometer is a product made from an aluminum alloy. Please apply a thin of silicon grease to the screw parts and you can mount smoothly.
Fixation with a Magnet
Although a magnet can be used when the measurement subject is made of the metal which sticks to a magnet, since contact resonant frequency falls, it is restricted to measurement for middle and low frequency.
Please fasten the bolting torque of a Accelerometer and a magnet by 1 - 1.5 N-m.

！！！！ CUTION
●●●● A magnet is very powerful (adsorption power 100N).
Please be careful not to be hurt enough, when attaching and detaching to a measurement subject. Moreover, what is influenced of magnetic should release a magnetic card etc. enough. It may destroy and break down.

Forcing by the contact pin
Measure in the place of an unfixable narrow place or a thin pipe where does not have sufficient contact surface product using a contact pin. Although it is the easiest method, 500 or more Vibration measurement cannot be performed because Contact Resonant Frequency falls very much,

※※※※The connector is one-touch type BNC connector. Do try to hold up the mark portion
todisconnect, not the accordion portion or the curl cable itself.
Also, during/after connection, make sure you do not try to rotate the connector itself,
which may leads failure or malfunction of any type.
