SECTION 7 MAINTENANCE
7.1 Cleaning the Colorimeter
Use a damp cloth to wipe the outside of the colorimeter
enclosure. Wipe up spills promptly. Use cotton swabs to clean
and dry the sample compartment if any spillage occurs.
Keep the colorimeter and sample cells clean at all times. Use a
lens tissue or a soft, lint-free cloth (that will not leave an oil film)
to wipe out the sample cell.
7.1.1 Cleaning the Data Transfer Adapter
Little cleaning is required of this adapter. Clean the outside and
inside with a barely damp cloth. Wipe up spills promptly.
7.1.2 Sample Cells
Clean sample cells with detergent, rinse several times with tap
water, and then rinse thoroughly with deionized water. Some cells
may require acid washing or other special cleaning procedures.
Refer to the Procedures Manual for additional information. Rinse
sample cells used with organic solvents (chloroform, benzene,
toluene, etc.) with acetone before the detergent wash, and again
as a final rinse before drying.
7.2 Replacement Instructions
To prevent static electricity damage to the instrument, always turn
the instrument off before removing the batteries.
7.2.1 Battery Replacement
When the LOW BATTERY icon appears in the display the
batteries must be replaced or recharged as soon as possible to
ensure proper instrument performance. Turn the instrument off
before removing the battery compartment door.
The correct date and time may need to be reentered after battery
replacement. See Section 2.3 Setting the Date and Time.
See Section 2.1 Battery Installation for complete
installation instructions.
