The Summary register is known as the Status Byte register and records high-level summary information acquired by the Event registers. An Event register report defines conditions or messages at each bit. The bits are latched and remain in an active state until the register is either Read or Cleared. Reading the Event register automatically clears the register and sets all bits to an inactive state or 0.
Page 97 After the serial poll (SPOLL) is executed the RQS bit will be cleared to 0 and the remaining bits will remain unchanged. The Status Byte will not change value until the Event register is read and cleared for the corresponding Status Byte bit. For example, after the All Pass SRQ has been enabled, when the test(s) have finished with pass indications the instrument will set the hardware SRQ line and output the Status Byte of 41 hex.

Page 147 620L system is a vector sum calculation. It should be noted that the term “620L system” refers to not only the 620L unit but also any other Associated Research, Inc. safety tester integrated with the 620L unit as well as any fixtures the end user may include to the system.
Page 148 The following example illustrates this point: Consider the network in Figure 1 as a simulation for a 620L system and DUT. The network consists of a 307.3pF capacitor to represent the capacitance of the 620L system. This is in parallel with a 5MΩ resistor to represent the DUT. The voltage source is generating 120V at 60Hz.
Page 149 DUT leakage current is 90°, the LLT Offset works optimally for this application. If the phase shift between the 620L system and the DUT is not 90°, the Displayed Current value will not be a valid representation of the leakage current flowing through the DUT.
Page 150 The introduction of the 1nF capacitor to the DUT in the second circuit causes the phase shift between the 620L system and the DUT to change from 90° to 62° (Idut = 51.2Angle(-62.0°)uA). As a result, the calculated value for displayed current does not match the theoretical value calculated above.
