parasitic serial and parallel resistance
cancellation.

Captures and freezes a stable measurement
result. Beeps when stable. Touch Hold
works on the main meter reading , with
threshholds of 1 Vpp for AC signals and
100mV for DC signals.
Graphs meter readings of the Min and Max
values from 15 s/div (120 seconds) to 2
days/div (16 days) with time and date
stamp. Automatic vertical scaling and time
compression.
Displays the actual and Minimum,
Maximum, or average (AVG) reading.
Possible by using attenuation keys.
