Normally only operational checks are made on geophones in the field because of the lack of suitable test equipment. The test method described here was developed to enable accurate (better than 1 %) measurements to be made, in the field, of all geophones in common use which have natural frequencies of i c/s or greater. The portable field instrument is simple to operate and can be used to test refraction and reflection geophones, either singly or in series strings.
