8 Instrument Maintenance
8.1 General Instrument Care
The instrument must be on a level surface to operate properly. Allow 7.5 inches (19 cm) of
clearance in front of the Modulus™ Microplate Reader so that the instrument door may open
without hindrance.
The maximum volume capacity per well is 250 µl. If a well is overfilled, immediately clean up any
spills.
Touch the DOOR button to automatically open and close the instrument door. This DOOR button
is located within the INSTRUMENT CONTROL screen on the bottom, right-hand corner of the
touch screen. The instrument door should be kept closed whenever possible to avoid damage.
To gain access to the inside of the instrument, manually open the door and hold it down with one
hand.
If the optional Microplate Sample Tray Cover is installed, it will also automatically open and close
when the DOOR button is touched. Do not use force to manually close the Microplate Sample
Tray Cover.
To start or stop a run, use the START and STOP button on the INSTRUMENT CONTROL
screen.
8.2 General Cleaning
Power off the Modulus™ Microplate Reader and disconnect the power supply whenever the
interior of the instrument is open for cleaning and maintenance.
Residue accumulated from various reagents may inhibit proper movement of the plate tray
assembly. Besides immediately cleaning up any spills, it is recommended that the interior of the
instrument be thoroughly cleaned every 30 days.
Periodically clean the Microplate Sample Tray, Microplate Sample Tray Cover, the Luminescence
Optical Lens, and the Fluorescence Module Mask with KimWipe

dampened with 70% ethanol.
Do
not allow excess solution to run-off onto other electrical components as this may cause
damage to the instrument and its electronics. Do
not
use solvents or abrasive cleaners.
Use a cloth dampened with deionized water to periodically wipe clean the exterior of the
Modulus™ Microplate Reader. Do
not
use solvents or abrasive cleaners.
WARNING: If a fluid spill on the detector is suspected,
immediately contact the Turner
BioSystems Technical Support Department for cleaning instructions.
