Accuracy obtained by doubling the measurement
range error for the accuracy when the crest factor is
set to 3
When the data update interval is 100 ms, and Auto,
add 0.05% of reading to the 0.1 Hz to 1 kHz
accuracy.
Add 0.02% of range/°C to the DC voltage accuracy.
Add the following value to the DC current accuracies.
