DP-40K HIGH VOLTAGE DIFFERENTIAL PROBE
1. FEATURES
The DP-40K differential voltage probe provides a safety means of
measuring floating potentials for all models of oscilloscopes
incomplete safety.
It converts the high differential voltage (≦ 40KV peak) into a low
voltage (≦ 4.0V) with reference to the earth for display on the
oscilloscopes. It is designed specially for high sensitivity using.
The BNC output is designed to operate on an input with an
impedance of 1 MΩ. It is 2 times of the 50Ω.
DP-40K can observe more exact measured testing voltage from
DMM. (Oscilloscope accuracy is 3%, and DMM is 10 times).
