When the least significant digit has been set pressing
the “ ” key will advance to the Potential Transformer
Primary Value confirmation stage.
Screen showing display of 0.120 kV i.e. 120 Volts
indicating steady decimal point and cursor flashing
at the “hundreds of volts” position.
Pressing the “ ” key sets the displayed value and
will advance to the “Potential Transformer Secondary
Value” screen (See Section 3.2.1.3).
3.2.1.3 Potential Transformer
Secondary Value
The value must be set to the nominal full scale
secondary voltage which will be obtained from
the Transformer when the potential transformer
(PT) primary is supplied with the voltage defined
in 3.2.1.2 potential transformer primary voltage.
Pressing the “ ” key accepts the present value at the
cursor position and advances the cursor to the next .
The ratio of full scale primary to full scale secondary
is defined as the transformer ratio.
The PT Secondary value can be set from 100VL-L
to 500VL-L.

If the scaling is not correct, pressing the “ ” key
will return to the “Potential Transformer Primary digits
flashing indicating Value Edit” stage with that multiplier
(decimal point position) should be selected.
