A Bit of Advice to Young Instrument Designers

What is this? A designer developing an instrument for testing analyzes all modes of its operation and selects an optimal one. In particular, if a manufactured product is issued in small batches, it is advisable to test this product manually, rather than to build an automated facility, for it is well known that man is the least expensive robot. If tests will be conducted in places to which access is difficult, e.g., at high altitudes, where the weight and overall dimensions are essential, hence the instrument should be designed as simple as possible with minimal dimensions, it is unreasonable to build an instrument performing various functions if this requires larger dimensions and complicates operational procedures.
