DO NOT USE CHEMICAL CLEANERS OR
SOLVENTS OF ANY TYPE. SOME CLEAN-
ERS ARE ABRASIVE AND MAY AFFECT

TESTING
Before servicing the balance, an operational test and various performance tests should
be made to ascertain whether or not the balance meets specifications. Turn the balance
on and allow it warm up for at least five minutes before performing these tests. Make
sure the test area is free from drafts and that the balance rests on a level and vibration
free surface. The masses used for the performance tests and adjustments must be
adjusted to ASTM Class 4 tolerance or better.
4.2.1 Operational Test
1. Connect a functioning AC Adapter to the balance power jack located at the
rear of the balance.
2. Plug the AC Adapter into a suitable power source. If the AC Adapter supplied
with the balance is rated for a different voltage, use an appropriate adapter
to match the supply voltage.
4.2.1.1 Segment Display Test
1. Turn the balance on by pressing ReZero On, all segments are enabled and
displayed briefly, then followed by a software revision number (which may be
different from the display shown below). This is a segment display test. See
Figure 4-3.
