High Voltage Differential Probe

DP-25 HIGH VOLTAGE DIFFERENTIAL PROBE

1. FEATURES
The DP-25 differential probe provides a safety means for
measuring differential voltage to all models of oscilloscopes.
The DP-25 converts the high differential voltage (≦1400Vpeak)
into a low voltage (≦7.0V, with reference to the earth) and display
on the oscilloscopes.
The DP-25 is designed to operate with the 1MΩimpedance
oscilloscopes. When combine with the 50Ω load, the attenuation
will be 2 times.
We recommend to use PINTEK PL-10 with DP-25 to expand the
measuring with DMM to observe more accurate measurement.
The accuracy of oscilloscope is 3% and the DMM is less than 1%.
NOTE: If you connect DP-25 to the DMM without PL-10, the
accuracy will be higher than 10%.

[N.B]
The real vertical deviation in V/div is equal to the attenuation
factor multiplied by the range of vertical deviation selected on
the oscilloscope. It will be doubled in the case of use of a 50 Ω
load.
Example:
With the probe on factor x 200, the oscilloscope on 0.5 V/div,
the real vertical deviation is 200 x 0.5 = 100 V/div.
With a 50Ω load on the input of the oscilloscope the deviation
becomes 200 V/div.
