· TOPCON TECHNOHOUSE will not bear any responsibility whatsoever for incidental damage
arising from the use or the inability to use the Spectroradiometer SR-LEDW/SR-UL2/SR-
UL1R/SR-3AR (loss of business profits, interruption of work, etc.)
· TOPCON TECHNOHOUSE will not bear any responsibility whatsoever for damage arising
from uses of SR-LEDW/SR-UL2/SR-UL1R/SR-3AR not in accordance with the instructions in
this manual.
∙ TOPCON TECHNOHOUSE will not bear any responsibility whatsoever for damage arising
from malfunction or the like due to connections with other devices.
Recommendations for Use
∙ Use only the AC adapter provided with the SR-LEDW/SR-UL2/SR-UL1R/SR-3AR or sold
separately specifically for the SR-LEDW/SR-UL2/SR-UL1R/SR-3AR. The using of adapters
other than the specified AC adapters may cause damage to the instrument. The input voltage
specification is between 100 and 240 V AC with a frequency between 50 and 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.
∙ Do not measure bright objects exceeding the measurement range including the sun. Doing so
may damage the light receiving elements, making future measurements unstable.
∙ Do not turn on the power of the instrument right after it is turned off. Sometimes the
protection circuit works because the in
strument’s inside is hot and so an error is displayed. In
this case, turn off the power first. Leave the instrument in the environment meeting the use
condition (SR-LEDW,SR-UL2,SR-UL1R:5-30
℃
) (SR-3AR:5-35
℃
)for about 30 minutes and
then turn on its power.

‘5.1 Error Display on the Instrument’
∙ Do not use the SR-LEDW/SR-UL2/SR-UL1R/SR-3AR in locations which are dusty or
extremely humid or where corrosive gases occur.
∙ Do not use the SR-LEDW/SR-UL2/SR-UL1R/SR-3AR in places with rapid temperature
changes. Although the SR-LEDW/SR-UL2/SR-UL1R/SR-3AR has an internal temperature
compensation circuit, rapid temperature changes may lead to unstable measurements.
∙ Avoid dropping and other strong shocks, and do not use or store the SR-LEDW/SR-UL2/SR-
UL1R/SR-3AR in locations with constant vibration. The SR-LEDW/SR-UL2/SR-UL1R/SR-3AR
has precision optical parts and such use or storage may lead to malfunction. When carrying
the instrument, place in its carrying case and avoid direct vibration or shock.
∙ Store in the provided carrying case at room temperature. Do not store it in hot or humid
environments (e.g., in a vehicle).
∙ In order to maintain measurement precision, run a calibration test about once a year. Consult
with your retailer or TOPCON TECHNOHOUSE regarding calibration.
∙ Note that all data stored in the instrument will be erased during calibration. Transfer all
required data to your personal computer before 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.
∙ The backup battery may be exhausted when the power of SR-LEDW/SR-UL2/SR-UL1R/SR-
3AR is OFF and the PC connection cable is connected while the PC is ON. We recommend
