Introduction
Thank you for purchasing the TOPCON TECHNOHOUSE Luminance Colorimeter RD-80SA.
The RD-80SA is the instrument to detect building-up/Falling down time of the light from LCD, LCD
backlight, and LED.
Read this manual carefully before using the RD-80SA 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, activate the Auto calibrate
function. 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 (optional accessory) when carrying it.
・When storing this instrument, put it in a carrying case (Optional accessory), 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 (Optional accessory),
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.

1.3Preparation
■Connecting AC adapter
Be sure to use the supplied AC adapter or a separately sold and
authorized AC adapter.
AC adapter failure may result in fire or electric shock.
Remove dust or moisture from the AC adapter plug.
Failure to do so might cause fire.
Do not plug in or unplug the AC adapter plug with wet hands.
Doing so might cause electric shock.
Connection procedure
1Confirm the power is OFF
2Connect the AC adapter plug to the DC input connector

3Plug the AC adapter to outlet.
■Connecting the PC
The RD-80SA can connect PC with RS-232C or LAN cable. Use RS-232C cable with Interlink cable
of serial cross type supporting for a DOS/V PC. Or use LAN cable category 5 or greater and straight
type.
The RS-232C signal line of the instrument is arranged according to the 9 pin D-sub being used in
the DOS/V PC.
Notice
The RD-80SA can connect RS-232C and LAN cable together.
But do not use both communications at the same time, otherwise the
system may be unstable.
・RS-232C and LAN cable are not included in standard package of the RD-80SA.
・About communication setting in PC, refer to instruction manual of the PC.
