Introduction
Thank you for purchasing the TOPCON Luminance Colorimeter BM-5AC.
This instrument is a Luminance Colorimeter for measuring light with high precision from a natural light
source such as a CRT, PDP
、
LCD
、
LCD backlight, LED, light-storing materials, or the like, or reflected
light from a painted surface or printed material.
Read this manual carefully before using the BM-5AC in work applications.
Precautions for Use
・
Be sure to only use the AC adapter supplied with this instrument, or a separately sold authorized
AC adapter. Using a non-authorized AC adapter may result in a malfunction. The input voltage
should be 100 VAC to 240 VAC, and the power supply frequency should be 50 Hz to 60 Hz.
・
For energy saving, when the unit will not be used for an extended period of time,
unplug the
power plug from the socket.
・
Keep the instrument away from water and liquid. This instrument is not water-resistant.
・
Before using this instrument, be sure to warm it up for at least 30 minutes. If this instrument is not
warmed up, output fluctuation may affect the measurement values, preventing highly accurate
measurement results from being obtained.
・
When using this instrument over a prolonged period of time, calibrate it on average once every 1
hour. Output fluctuation of the photo detector may prevent highly accurate measurement results
from being obtained.
・
Do not use this instrument for measuring bright objects that exceed the measurement range, or
for measuring extremely bright objects such as the sun. Doing so may damage the photo
detector and prevent stable measurement.
・
Do not use this instrument in dusty, very damp or humid areas, or in areas where corrosive gas
may be generated.
・
Do not use this instrument in areas where sudden changes in temperature might occur. This
instrument contains a temperature compensation function. However, stable measurement may
not be possible in environments where there are sudden changes in temperature.
・
Do not subject this instrument to heavy impact such as dropping it. Also, avoid using or storing
this instrument in areas subjected to constant vibration. This instrument uses high-precision
optical parts and subjecting it to harsh conditions might cause a malfunction. Prevent this
instrument from being subjected to direct vibration or impact by placing it in a carrying case
when carrying it.
・
When storing this instrument, put it in a carrying case, and store it at room temperature. Do not
store the instrument in a hot or humid environment such as inside an automobile.
・
To maintain measurement precision, perform calibration and maintenance on average once a
year. When performing calibration, consult with your dealer or Topcon Technohouse Corporation.
・
When requesting calibration, put this instrument in its carrying case, and then put it in a
cardboard box packed with shock-absorbing material before sending it.
・
When calibration is performed, the measurement data stored in this instrument is deleted. Be
sure to transfer the measurement data to a PC before requesting calibration.
・
Please do not peel off the sticker stuck on the back of the main unit. If you peel it off, all warranty
will be invalid.
