CHAPTER 2 DIAGNOSIS
2.1 TROUBLESHOOTING
This section of the manual specifies problem areas of the balance which can occur. Information is
contained to isolate specific problems using Table 2-1, Diagnostic Guide, and Table 2-2, Error Codes.
Follow all directions step by step. Make certain that the work area is clean and use care when handling
components of the balance.
2.2 DIAGNOSTIC GUIDE
Table 2-1 is a diagnostic guide designed to help locate the problem area quickly and easily. To use
the table, first locate the symptom that you are observing. Follow the symptom column and review the
probable cause column and remedy column. The probable causes are listed with the most common
cause first. If the first remedy does not fix the problem, proceed on to the next remedy. Before
attempting to repair the Balance, read all chapters of this manual to familiarize yourself with the
balance components and operation. Do not attempt repairs unless you fully understand the operation
of the balance.
2.2.1 Diagnosis
1. Isolate and identify the symptom.
2. Refer to Table 2-1 Diagnostic guide and locate the symptom.
3. Follow the suggested remedies in the order that they appear.
4. Perform the indicated checks, or see the appropriate section of the manual.
5. Repair or replace the defective section of the balance.
NOTE:
If more than one symptom is observed, it is necessary to
approach one area at a time, and also remember, that the
symptoms may be interrelated.
In the event that erratic or fluctuating weight readings are observed, it is necessary to isolate the
problem to either the mechanical area or the electronic area of the balance. The repeatability test will
quickly point out whether the Transducer (8) is operating properly or whether the problem is due to an
electronic malfunction.
If a problem arises that is not covered in this manual, contact Ohaus Corporation for further information.
