*1  Accuracy:
 Defined at 23 ± 5°C, 45 to 75% RH.
Defined with sign wave of input frequency 40 Hz to 1 kHz.
Defined ±0.2% F.S. for less than 10% input value.
*2  Shunt resistance:
with 0.1 Ω external resistance.
      Temperature coefficient:
  ±300 ppm/°C (Temp. range 0 to 50°C)
      Crest factor:
4 (The peak of 3125-26 is 500 V, the peak of 3125-36, -37 is 3 A)
Display will be 0 when the rated input will be less than 0.1%
