5. Preparing the main unit
* Clean the measurement window. If it is not clean, measurement may not be performed correctly.
* Whenclosing/openingthelightshieldingcover,becarefulnottopinchthengers.
⑤Turn on the power switch.
Turn on the power switch located at the rear of the
unit.
⑥Warm up the unit.
 Whentheunitispoweredon,therotationtablewill
automatically start rotating to warm-up. At the same
time, a message "SET THE STD PL." will be dis-
played. Set the zero-adjustment plate if it was not set
in step (4).
 Whenthewarm-upisdone(after5to6minutes),the
indication"WARMINGUP"turnsoffandthezero-cali-
bration screen will be displayed.
⑦Perform zero-adjustment.
Press the [ENTER] key to execute zero-adjustment.
The zero-adjustment will proceed while displaying
theabsorbanceinreal-time.Whenthecalibrationis
completed, the initial screen will be restored.
* If the power is cycled, repeat the operation from step (6).
Make sure that the zero-adjustment plate is set.
①
Install the main unit.
 Installtheunitinaplacewheredirectsunlightisavoidedandnotbesubjectedtosignicantvibration.
②
Attach the light shielding cover.
Attach the light shielding cover by inserting the columns provided on the top surface of the unit into the
mounting holes on the cover.
③Connect the power cable.
Connect the main unit and the power cable.
Plug into the socket, and make sure to ground.
④
Attach the zero-adjustment plate.
Open the light shielding cover, and set the zero-adjustment plate onto the rotation table of the unit. Then,
close the cover.
