Beginning Set-Up and Testing

This manual has been prepared to guide you in the use of UDY instruments. Most instruments are shipped with all parts, accessories, and supplies needed for sample testing. The following pages will provide the information typically needed to use the instruments. Little previous knowledge or skill will be assumed. Some information given here is not appropriate for all applications and some information may be familiar to you already.

If a point is not clear, contact us. We are available to help you. Sometimes a brief call can save hours of uncertainty.

Remember the basic steps are simple. Do not become dismayed by the many details presented here. As you become familiar with test procedures, they quickly become automatic. Also, some things are easy to demonstrate and perform, but difficult to explain. The illusion of difficulty, caused by unfamiliar items and detailed explanations, is frightening at first, but passes rapidly.

While not becoming lost in "little" details, keep in mind that every instruction is included for a reason and should not be overlooked unless you are positive it is not applicable. Once you are testing successfully, go back occasionally to review the basics and details. Prevent bad habits from creeping into your technique. It is the little details that are easily overlooked that cause the most problems. Do not look just for complicated problems when questions arise. Instrument malfunctions are very rare.

General information and set-up information are given in sections on Sample Preparation, Balances, Dispensing, Reagent Solutions, Extraction-Reaction and Measurement. Specific procedural information is given in the Procedure--Tables section. Individual procedure sheets identify items needed for specific procedures. Major equipment items, their illustrations and applications are identified in the following table and brochure.

If you have not already identified all the items you received, we suggest that you go through the Packing List (copy in the back of the manual) to identify all parts. Having them available for examination while reading the manual, before beginning instrument set-up, is desirable.
