Describe the dial settings
Send the resistance represented by one step of each dial, the overall range and the unit. A photograph of the front panel helps distinguish two similar boxes with different lowest decades. Identify any intermittent switch or damaged terminal without altering the box before assessment.
Which terminals define the result?
At low settings, contacts and connecting leads can matter alongside the selected resistance. Describe the terminals and two- or four-wire arrangement used on your bench. Say whether your records require a zero-setting result, individual dial checks or complete combinations.
A setting made up from several dials
Suppose a fixture needs 138.5 ohms and the operator obtains that value by adding the settings of four dials. A report covering only one step on each dial would answer a different question from a comparison at the assembled setting. Put the complete value on the request and list the dial positions beside it.
If the process uses a second value a fraction of an ohm away, include the smallest step used and how the box connects to the fixture. The return report can then be checked against both rows of the bench procedure.
Return to the correct fixture
At an IMT Sohna electronics bench, note which leads belong to the resistance box and which stay with the fixture. Label both if the job requires the complete connection arrangement.
