20 : 10 : 39 : 54 . Data collection for the signature test. During the signature test, individual pieces of major current drawing equipment shall be started and stopped. The effects of starting, operating, and stopping each piece of equipment are measured and recorded for a period of operation of not less than 15 seconds. The qualified testing professional conducting the test shall identify and record the equipment being tested and record the specific times the equipment was started and stopped. A digitizing data recorder with averaging capability shall be used to measure and record the required electrical data. The measurements shall be taken at the same locations at the dairy where the measurements were taken for the load box test and the 48 hour test. The following measurements shall be taken:

1. (1) Voltage from primary neutral at the transformer to remote reference electrode;
2. (2) Voltage from secondary neutral in the service panel serving the area of the cow contact point to remote reference electrode;
3. (3) Voltage from primary neutral at the transformer to secondary neutral at the service panel serving the area of cow contact; and
4. (4) Cow contact voltage or cow contact current at the preselected point.
