Fluke 515A - 4.5 AC FREQUENCY RESPONSE TEST UP TO 50 KHZ

4.4.3 Set the dc voltage standard for a 10V output and adjust it as required to establish a reference null
indication on the 10 V range of the null detector.
4.4.4 For each of the following TI output and voltage divider setting verify that the null detector indication is
within the tolerance limits listed.
