Signal
Sine wave: 54.5 Hz, < 2 V
1. Overload protection: 1000 VRMS for short circuits with < 0.3 A current
2. The accuracy for all ranges is speciied based on a ilm capacitor or better, and after the Null function is used to subtract the residual values (by
opening the test leads)
3. The maximum display is 1200 counts
4. Add additional accuracy of 0.1% per μF for values greater than 50 μF ฀ for example, 100 μF, additional accuracy of 5% is to be added

1. Overload protection: 1000 V; input signal is < 1,000,000 V × Hz (product of voltage and frequency)
2. The frequency measurement is susceptible to error when measuring low-voltage and low-frequency signals. Shielding inputs from external noise
pickup is critical for minimizing measurement errors.
