Measuring Characteristics: Measurement method: Reciprocal-counting technique. AC-coupled input using the ac voltage measurement function. Voltage ranges: 100 mV rms full scale to 300 V rms. Auto or manual ranges. Gate time: 10 ms, 100 ms, or 1 s 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 s) 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.
