High Accuracy Digital Multimeter with USB Interface
Capacitance
NNootteess::
above accuracies for film capacitor or better can be guaranteed within the
full range.
Diode
NNootteess::
the test current is about 0.7mA.
Logic Frequency
Linear Frequency
NNootteess::
Low voltage or low frequency would lower the accuracy.
