| *1 If the distance to the sensing target is shorter than the reference distance, even if the conditions are within the measurable range, measurement cannot be performed up to the upper limit of the measuring range. *2 Within ±100 V when using high-precision mode; within ±1 kV when using wide-range mode. In other ranges, display value has an accuracy of ±10% (display value). Values are obtained from a mean of 256 measurements. *3 Measuring accuracy is satisfied in the range of ±30 kV. *4 25°C, 50% RH. *5 OP-87934 is required. *6 Within ±100 V. In other ranges, display value has an accuracy of ±10% (display value). |
