±[(0.07×f)% reading + 0.3% range]

Temperature coefficient

5 to 18°C or 28 to 40°C: Add ±0.03% of reading.

When the power filter is on

<45Hz: add 0.5% of the reading;

45~66Hz: add 0.2% of the count

Crest Factor Impact

The range error when the crest factor is 6 is twice the range error when the crest factor is 3.

Effect of temperature change after zero calibration or range change

Add 0.02%/°C of range to DC voltage accuracy.

Add the following values ​​to DC current accuracy:

200mA and below range: 5uA/°C;

0.5A and above range: 500uA/°C.

External sensor input: 1mV/°C.
