Quickly Verifying the EZCT S2A’s Turns Ratio Circuit
You can quickly verify the EZCT S2A’s turns ratio circuit by performing the following ratio test:
a. Connect the X1 test lead to the H1 test lead as shown in Figure 17.
b. Connect the X2 test lead to the H2 test lead as shown in Figure 17.
c. Run a turns ratio test (see section 3.2.2).
d. Observe the turns ratio test on the LCD screen. The turns ratio should be 1.000 since the
excitation voltage is the same as the sensed voltage.
