TIP MIN, AVG, and MAX values are measured as soon as the power is
turned ON. Pressing the Enter button resets these values and begins a
new update.
The MAX and MIN measurements are calculated every half period (for
example, every 10 ms for a 50 Hz signal). The AVG measurements are
calculated every second. However, the MAX, AVG and MIN
measurements are refreshed every 250 ms.
