The ELV Energy Master Professional is to instructions ELV Energy Master 2, which provided only for a bit of confusion.
The little booklets of the manual I had to read more. (Read after repeated) actually well understood the many display options by a few buttons did not adjust or can find initially.
Just this many display options make the instrument a versatile tester.
All consumption values on day, week, month, year one can be extrapolated and display in Euro, kWh. Readings as reactive and apparent power are displayed as well as the current consumption in watts.
Three different flow rates can be saved and 10 presets for various devices are available. The measurement can be interrupted to be continued with another consumer, then again, measure the first consumer.
Accuracy is according to instructions:
up to 10W at 1% +/- 1 digit,
up to 100W at 1% +/- 3 Digit,
from 100W at 1.5% +/- 3 digits. Under digit refers to the last digit of the display.
As a self-consumption of the meter 0.5W be specified.
Consumption can to 14A permanently and then to 16 A for max. 30 minutes measured.
