●ワーク端面(Z)基準位置検出および工具長検出
Detecting position of workpiece end surface (Z) and length of tool.
ワーク端面にベースマスターミニ(BMM-20H)を取り付け、工具を測定面に接触させると同時にLEDが点灯
します。この位置がワーク端面から20mmの位置になります。工具の長さを測定する場合は、基準工具と他の
工具の接触位置の差により工具の長さを検出することができます。
Mount the BMM-20H on the workpiece end surface. Move the tool until it touches the sensor plate, which will
instantly light the LED lamp. This will then give you an exact reading of 20mm distance from the workpiece
end surface to the tool. Tool length can be measured by comparing the contact positions between the
reference bar and the actual tool.

1.
Turn and remove the battery cap using a coin or similar and load the 2 batteries (SR44) as
illustrated right and tighten the cap. If set reversely, the LED does not turn on.
必ず本器の測定面・底面及びワーク取り付け面の油分やゴミを取り除いてから測定を行ってください。
3.
Completely remove oil, dust, etc. from the sensor plate, unit sole and mounting surface prior
to measuring operation.
内部の精密スライド部やシール部の潤滑油が硬化して測定子のストロークが不安定な場合が
ありますので測定子を数回軽く押してからご使用ください。この際にLED(緑)の点灯を確

2.
The lubricant around the slide shaft and the sealing may harden under the circumstances
such as cold weather or prolonged non-use. This may cause decient stroke of the sensor
plate. Lightly press the sensor plate several times before use. At the same time, make sure
the LED (green) turns on each time. If it does not turn on or light only feebly, the batteries
are low or have run out. Replace the batteries with new ones.

・ワーク端面中央にへそが発生している場合は測定誤差が生じますので、可能な限りへそがない状態にしてください。0.5mm以下のへそであれば、ベー
スマスターミニ(BMM-20H)中央部の逃がしで回避することができます。また、端面側にバリが発生している場合は測定誤差が生じますので、端面
側のバリを除去してから測定してください。
・Center stub, which is convex burr at the center of the workpiece end surface, may cause a measuring error. Remove it as much as possible.
BMM-20H has a recessed hole at the center of the bottom surface so that it can avoid interference with the center stub as far as its height is no more
than 0.5mm. Burrs remain other than the center of the workpiece surface must be removed before the measurement to prevent errors.

Mount the BMM-20H on the workpiece surface. Move the spindle or "Z" axis carefully until the tool touches the sensor
plate, which will instantly light the LED lamp. This will then give you an exact reading of 20mm distance from the top
surface of the workpiece to the tool.Tool length can be measured by comparing the contact positions between the
reference bar and the actual tool.
●加工物側面(X,Y)基準位置検出および工具径検出
Detecting position of workpiece surface on the "X" and "Y" axis and diameter of tool.

Mount BMM-20H on the side surface of workpiece and move the spindle, "X" or "Y" axis carefully until the tool touches
the sensor plate, which will instantly light the LED lamp. This will give you an exact reading of 20mm distance from the
reference surface to the tool. Then add 1/2 the diameter of the tool to give you the machine spindle center distance.

・Do not immerse the BMM-20H directly into gas oil for washing.
・
Take out the batteries when not using the BMM-20H for extended periods.
・Do not disassemble the BMM-20H.
・Store the batteries in a safe place out of reach of babies to prevent
swallowing. Dispose used batteries in a prescribed way.
・Replace two batteries at the same time when voltage becomes low.
・The precision electronic parts are contained. Take care not to
splash any coolant and avoid any accidental collisions. Do not
leave it on the machine table or the jig when not in use.
・Remove coolant immediately if it is attached to the BMM-20H.
・Specications and height are the gures under measurement
environment at a temperature of 20℃±0.5℃(equivalent to 68°F)
and at a humidity of 55%±5%. For precise measurement under
different environment, compare the height with a block gage and
compensate the difference.
・Use under low temperature below 5℃may worsen movement of the
sensor plate.
・If an accuracy problem or any malfunctions occur, immediately stop
using the device and contact us through distributors.
・測定面や本体底面の汚れた本器を使用して測定した場合、測定誤差が生じます。
そのまま加工に入ると刃具、加工物、機械等を破損する恐れがあり、また、そ
の破片で人体に危険を及ぼす恐れがあります。
・本器測定面に工具を早送りで近づけるときは余裕のある位置で止め、残りはゆ
っくりハンドルで送ってください。万一、早送りのままで本器にぶつかった場
合、本器や刃具、加工物、機械等を破損する恐れがあり、また、その破片で人
体に危険を及ぼす恐れがあります。
・Measurement may be in error, if the sensor plate or sole plane is
soiled. Any attempt to commence machining after a false reading
may lead to damage of the tool, workpiece, machine, etc. and
broken parts could endanger persons in the area.
・When any tool approaches the sensor plate at a high feed rate, then
it should be arrested at a sufcient safe distance to allow the nal
approach at ne feed by hand. Should the tool collied with the
BMM-10H at a high feed then damage may be caused and broken
parts could endanger persons in the area.

・工具の先端部を測定面の中心に合わせて、測定を行ってください。中心よりズレますと、工具の破損や測定
が正確に行われない恐れがあります。
・工具を測定面にタッチさせる時は、タッチスピ−ドが速いと工具破損する恐れがありますので、ゆっくりと
慎重にアプロ−チを行ってください。
・測定子は2mm以上押し込まないでください。
