TESTING

Before and after servicing a Valor 2000/4000 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 2000/4000 scales must meet the requirements of
ASTM Class 4 or OIML F2 Tolerance. The mass values are listed in Table 4-1.
4.2

Operational Test

1. Connect a functioning Power cord to the back 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 and
followed by a software revision number.
