Attention:

1.Include a current transformer, no need to buy it separately.

2.Please try not to install the meter and current transformer around the high temperature, strong magnetic field

   and large transformer, otherwise the accuracy will be affected.

3.In order to obtain a higher precision measurement, it is recommended to "preheat for 5 minutes" before

   adjusting the calibration.

4.Since the 24V battery charge full of floating voltage may be over 30V, so "no" recommended direct use it.

5.When you select range, not the larger the better. the larger the range, the larger the error, it is recommended

   that it is 1.5 or 2 times as large as the actual test value.
