XIII. Technical Specifications
Accuracy: ± (a% of r 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”.
