Measuring Characteristics
Frequency and
Period
Measurement
Method:
Reciprocal-counting technique. AC-coupled
input using the ac voltage measurement
function.
Voltage Ranges
100 mVrms full scale to 750 Vrms. Auto or
manual ranging.
Settling
Considerations
Errors will occur when attempting to measure the frequency
or period of an input following a dc offset voltage change.
The input blocking RC time constant must be allowed to
fully settle (up to 1 sec) before the most accurate
measurements are possible.
Measurement
Considerations
All frequency counters are susceptible to error when
measuring low-voltage, low-frequency signals.
Shielding inputs from external noise pickup is critical for
minimizing measurement errors.
