TESTING

Before and after servicing a Valor 2000 scale, an operational test and various performance tests
should be made to confirm that the scale meets specifications. Turn the scale on and allow it to
warm up for at least one hour before performing these tests.
Make sure the test area is free from drafts and that the scale rests on a level and
vibration-free surface.

4.1.1 TEST MASSES REQUIRED

The masses required to test the Ohaus Valor 2000 scales must meet the requirements of ASTM
Class 4 or OIML F2 Tolerance. The mass values are listed in Table 4-1.

Operational Test

1. Connect a functioning Power Adapter to the scale power receptacle located on the
bottom of the scale.
2. Plug the Power Cord into a suitable power source, or power the scale on using
battery power. (Assure that the battery is charged beforehand.)
4.3

Segment Display Test

Turn the scale on, and ensure that all segments are enabled and displayed briefly. The
scale's model number appears next, followed by a software revision number. This is a
Segment Display Test. (See Figure 4-1.)
