10.0 Maintenance
This section contains information about IQ6200/6500 maintenance. Preventive maintenance consists of
periodically cleaning the external surfaces of the scale and should be performed as often as operating condi-
tions warrant. Service or repair should be attempted by qualified personnel only, and only when it has been
positively determined that the counting scale requires such service. All service should be done in a clean, dry,
dust-proof area. See Section 13, IQ6200/6500 Limited Warranty, for more information on service and repair.

Warning
Do not attempt any service while the scale is connected to the power cord.
10.1 External Maintenance
The exterior surfaces of the counting scale can be cleaned using soap and water. However, extreme caution
should be used so that no water penetrates the electrical or mechanical sections. A damp cloth or sponge is
suggested.
! Caution
Never use acetone, MEK, or similar solvents on the plastic housing as they will etch these surfaces. For
grease or other difficult spots, a chlorothane or naptha based cleaner may be used. Never use solvents on the
front or rear panels.
Accumulations of dust or dirt particles between the pins of the connectors may be removed by using dry
forced air or a small dry brush.
10.2 Internal Maintenance
Internal maintenance is not normally required. If needed, maintenance should only be attempted by a quali-
fied, authorized service technician. However, you should perform both an electrical test and an accuracy test
every six to twelve months. For an electrical test, follow the procedures in Section 3.3.
The scale weighing accuracy can be determined by applying known weights to the platform. Because of the
scale’s very high accuracy, only weights that are certifiably more accurate than the scale’s specifications
(NBS class “F” or higher) should be used in testing for accuracy. Rice Lake Weighing Systems is a certified
manufacturer and testing laboratory for test weights.
