Table 4 illustrates how to combine the branch circuit measured values with the
specifications from Table 2 to create a table of values between which the SureTest
reading should fall between to verify that it is with calibration.

The GFCI / Time test cannot be done in the field
High Resistance Ground Fault Test (GFCI)
A ground fault circuit-interrupter, the device should be capable of interrupting the
electrical circuit when there is a fault between 6mA and 264 mA with in the time interval
of T in the following relationship
