Output measured from standard ParaZapper
full_current_8_ma_at_2500Hz no_current_at_2500Hz
Shows full output current of 8.0 ma at 2500Hz
dry_copper_paddles_at_2500Hz dry_wrist_straps_at_2500Hz
shows that with dry bare copper paddles at 2500Hz the signal is reduced
shows almost no signal with dry wrist straps at 2500Hz
saline_wet_paddles_at_2500Hz saline_towels_under_wrist_straps_at_2500Hz
Using paper towels wetted with saline solution improves signal at 2500Hz
Even with saline soaked paper towels at 2500Hz wrist straps are not as effective. Note the high spikes which indicate loss of high frequencies which are important.
proper_current_measurement Current measuring criteria
ParaZapper and ParaZapper PLUS only

Current measured across R1 gives 1% accuracy.
output = 1 volt / milliamp current.
Measurements made with Tektronix Model 464 Storage scope.
Vertical set at 2.0 Volts per div.
Horizontal set at 50 microsec per Div for 2500 Hertz range.

Horizontal set at 5 microsec per Div for 30000 Hertz range.
full_7.8_ma_output_at_30kHz approx. 5.2 ma w/saline_wet_paper_on_handles_at_30kHz
7.8 ma peak current output at 30kHz
5.2 ma output with saline wet paper on handles at 30kHz
Using a multimeter or milliamp meter does not produce correct results as the signal is a square wave, not a DC or an AC current.
