Figure 18-0. Nameplate Voltage Selection Menu

a. Description: This menu allows the operator to use the transformer nameplate voltages to derive
a calculated turns ratio. This calculated turns ratio is then used to compare with the measured turns
ratio, which produces an error-difference percentage.

b. Origin: This menu is displayed after the operator selects the transformer type to be tested.

c. Action Option: Press key 1(yes) to use the calculated ratio in the test results. Press key 2 (no) to
bypass this option.
