Measuring Characteristics
Frequency and Period
Measurement Method:
Reciprocal-counting technique. AC-coupled input using the ac voltage
measurement function.
Voltage Ranges:
100 mV rms full scale to 300V rms. Auto or manual ranges.
Gate Time:
10 ms, 100 ms or 1 second.
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 adequately settle (up to 1 second) 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.
