*1 Obtained with a measurement distance of 8 to 12 mm and an electrostatic charge of ±100 V or less. When the charge is ±100 V to ±5 kV, the measurement accuracy is ±10% of the measured value.
*2 When ambient temperature is fixed at 25°C.
*3 Obtained with a measurement distance of 68 to 72 mm. When the charge is ±10 kV to ±30 kV, the measurement accuracy is ±5% of the F.S.
