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.
4.4.5 Set the equipment control(s) for minimum voltage output, and disconnect the test configuration.
4.5 AC FREQUENCY RESPONSE TEST UP TO 50 KHZ
4.5.1 Connect equipment as shown in Figure 5.
