Input Protection
500 volts dc or rms ac
Note
When the meter is set to measure frequency and there is no input signal
(i.e., input terminals are open), the meter may read approximately 25 kHz
(rather than the expected zero). This is due to internal capacitive pickup of
the inverter power supply into the high-impedance, input circuitry. With
source impedance of <2 k
Ω
, this pickup will not affect the accuracy or
stability of the frequency a reading.
