DP-25 HIGH VOLTAGE DIFFERENTIAL PROBE
1
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%.
