*1 Conforms to JISC1111. Error in dedicated CT is not included. For ambient temperature of 23°C, standard input, standard frequency, and
higher harmonic wave, the 2nd-, 3rd, 5th-, 7th-, 9th-, 11-th, and 13-th orders are supported.
*2. Calculation formula: Power factor = Active power/Apparent power
Apparent power = √(Active power)
*3 If the protocol is switched to Modbus, the setting value may be changed. When switching DIP switches, check the setting contents.
