Using matr1x 16.5 CFSDEEP IDLE ONWhen I was reading the values from the multimeter, they were usually steady. However, sometimes they jumped between maximum and minimum values constantly, and other times the reading just 'ticked' a little (less than 1dBu movement) - I have indicated these occurances in the Test Info. column. For governor tests, this could indicate switching of processor frequencies.Multimetershttp://goo.gl/rKsZr
