XIII. Technical Specifications
Accuracy: ± (a% of reading + b digits); guaranteed for one year
Ambient temperature: 23°C±5°C
Relative humidity: < 75%
Note:
 The temperature condition of accuracy is 18°C~28°C, the fluctuation range
of ambient temperature keeps within ±1°C. If the temperature is <18°C or
>28°C, the additional error of temperature coefficient is “0.1 × (specified
accuracy)/°C”.
