Furthermore, using a traditional goniometer takes valuable time. The instruments included altimeters, thermometers, compass, clock, and a Telefunken P63N radio goniometer. The original manual contact angle goniometer used an eyepiece with microscope. The adhesion characteristics can be observed and tested with a goniometer test. L is the goniometer radius 12 . Historically crystal shape was defined by measuring the angles between crystal faces with a goniometer. The universal standard goniometer is a plastic or metal tool with 1 degree increments. These angular measurements for the edges are made using a goniometer. A goniometer adapted for surround metering is called a 'jellyfish display'. The goniometer is used to position the crystal at selected orientations. In a single-crystal X-ray diffraction measurement, a crystal is mounted on a goniometer. Prior to the invention of the theodolite, the goniometer was used in surveying. A goniometer was used to improve the directional accuracy from the multiple receiving antennas. The FRD-10 used a goniometer to rapidly scan through all the antennas around the circle.
