The unit has some scuffs and wear from use including a small split in the insulation on the cord and a little writing on the back. We tested it to power on as shown. Due to time constraints and a lack of experience with this item, no further testing was performed.

The 691 FM Modulation Monitor/Test Set is a high technology, precision instrument employing a combination of new techniques in a single, highly versatile, but very compact package. It has been designed to be a complete FM test package with facilities for all proof-of-performance measurements and a wide range of trouble-shooting tests. Operator convenience and simplicity of use were primary considerations in the design of the 691. Component selection and device ratings are such as to enhance the instrument's reliability even with adverse handling. The 691 occupies only 10-1/2" of vertical rack space in a standard 19" rack.
