During many further and advanced training program seminars at the Testo Academy, the hope was frequently expressed that the learning material could be condensed into written form and made available as a handbook. We are pleased to be able to fulfil this request by publishing this Field Guide.
We hope that you find some helpful tips and tricks in this guide, which you can put to use when carrying out your day-to-day tasks. If you find that an issue has not been dealt with in sufficient detail, then we would be happy to receive your proposals, amendments or suggestions for improvement.
