Select 3V or 4A with to obtain the MIN, AVG, MAX, or PEAK values for current
or voltage. Select L1, L2 or L3 to obtain these values for an individual phase.
MIN, AVG and MAX values are measured as soon as the power is turned ON.
Pressing the enter button will reset these values and begin a new update.
NOTE: The MAX and MIN measurements are calculated every half period (e.g.
every 10ms for a 50Hz signal). The AVG measurements are calculated every
second. However, the MAX, AVG and MIN measurements are refreshed every
250ms.
