The indicator rating is the input value corresponding to the maximum scale value.
Generally, the secondary side rated voltage of a VT is selected as the rated voltage
and the secondary side rated current of a CT is selected as the rated current.
Generally, the secondary side rated voltage of a VT is selected as the indicator rating.
The indicator rating is the input value corresponding to the maximum scale value.
Generally, the secondary side rated voltage of a VT is selected as the indicator rating.
Black (B) needles are standard specification. Transparent (T) and special color (F) needles can also be
manufactured. (Transparent cover (G) needles can only be manufactured for the Y-N and Y-2N Series.)
Black (BR), transparent (GR), and special color (FR) needles are available.
(Please note that not all options are available for all models.)

Refer to the “Special Specifications” section on page 10 for information regarding specifications for environments where there are special conditions
such as high temperature/humidity (moisture-proof treatment), corrosive gases (supplementary anti-corrosion treatment) or high-frequency circuits.
Select a value that is 1.5 times or more than the load current.
When combining with a shunt, in general, make a selection that matches the rated value of the shunt.
Select a value 1.2 to 1.5 times the circuit voltage.
The selection should have a maximum scale value approx. 1.5 times the load current.
When combining with a current transformer (CT), make a selection that matches the rated value of the CT.
Select a value 1.2 to 1.5 times the circuit voltage.
When combining with a voltage transformer (VT), select a value approx. 1.36 times the rated value of the VT.
Select according to the calculation result of: VT ratio ✕ CT ratio ✕ indicator rating (Po).
Refer to the “Scale Selection Reference Table” (wattmeter: p.56; varmeter: p.60).
Select so as to match the rated value of the device that the indicator is combined with (e.g., transducer, sensor).
The standard scale is LEAD 0.5–1–LAG 0.5.
A LEAD 0–1–LAG 0 scale can also be manufactured (values between 0 and 0.5 are for reference only).
Select according to the frequency of the circuit to be measured.
In general, for 50Hz, select a 45–55Hz scale; for 60Hz, select a 55–65Hz scale and for 50/60Hz
common use, select a 45–65Hz scale.
Select so that the maximum scale value is the measured circuit’s voltage or 1.35 times this value.

specifications
A selection should be made so that the maximum scale value is approximately 1.2 to 1.5 times the
rated value or the steady-state value of the circuit to be measured.
For the maximum scale, any of the following values are recommended (or any of these values
multiplied by 10 resulting in a whole number).
1, 1.2, 1.5, 2, 2.5, 3, 4, 5, 6, 7.5, 8 (4.5 and 9 are also recommended in the case of voltmeters)
The secondary side rated voltage of a VT is selected as the rated voltage and the
secondary side rated current of a CT is selected as the rated current.
Additionally, the rated power (or rated reactive power) Po is selected to be within a
range of 0.8 to 1.2 times the secondary side rated power of the transformer (VT, CT).
