Toyo Keiki
Toyo Keiki CF Series Wattmeter and Varmeter
Product Made In Japan
Manufacturer: Toyo Keiki
Model: CF Series
Features
1. Meter has a bright scale face due to the wide cover lighting surface.
2. Accuracy of readability has increased due to the long scale length compared to the meter’s size.
3. A variety of sizes are available so you can choose a meter that best suits the size of your switchboard.
Features Cover eliminates static electricity.
Equipped with special anti-static resin.
Maintaining an anti-static finish is not necessary.
Static phenomena will not occur even in low humidity.

Remarks
VT and CT Usage Use a 110V5A rating meter combined with VT and CT if the rating above is exceeded.
Measurement Range Value Select the measurement range from the standard table of wattmeter measurement range chart on P30.
Production Limits of Meter For the production limits of meters, see P31.
Usable Voltage Range Rated voltage within ±15%
Varmeter Scale The standard scale of a varmeter is LEAD□□0LAG□□kvar.
Note) Pulse meters (0~□□kvar) can also be manufactured. (for zero-left meters, designate LEAD or LAG.)
Meter Wiring
- You cannot obtain a normal indicator if phase is reversed. Therefore, be sure to check the phase sequence of the bus and the polarity of VT and CT.
- For phenomena related to miswiring, see P32.
1P3W Wattmeter 1P3W wattmeters can be manufactured in compliance with the 3P3W wattmeters listed above.
Note
Voltage rated value 1A meters can also be manufactured.
