TECHNICAL SPECIFICATIONS
Accuracy is guaranteed for one year.
Ambient temperature: 23°C ± 5°C (73.4°F ± 9°F), relative humidity ≤75%.
Caution
• For accuracy, the temperature conditions should be controlled between 18°C and
28°C, while the uctuation range of the ambient temperature should be stabilised
within ±1°C.
• If the temperature is lower than 18°C or greater than 28°C, the additional
temperature coefcient error shall be 0.1 x (specied accuracy)/°C.
• If the change in ambient temperature is within ± 5°C, the accuracy is applied after
2 hours. Upon the completion of battery charging, the accuracy is also applied
after 2 hours.
