Note:
1. The temperature coefficient accuracy is used for the situation when the ambient is beyond the
accuracy-permitted temperature. This accuracy should be added into the voltage accuracy and the
current accuracy written above.
2. The power meter should be in a thermally stable environment with power turned-on for at least 1
hour before performing auto-calibration (ACAL).
