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 (MAX. Bandwidth: 75 MHZ).
It converts the high differential voltage (≦ 40 KV peak) into a low
voltage (≦ 4.0 V) with reference to the earth for display on the
oscilloscopes. It is designed specially for high voltage using.
The BNC output is designed to operate on an input with an
impedance of 1 MΩ. It is 2 times of the 50 Ω.
DP-40K can observe more exact measured testing voltage from
DMM. (Oscilloscope accuracy is 3%, and DMM is 10 times).

(1) Please DO NOT hold the probe itself when measuring the high
voltage is over 1 KV. Please put the probe itself on the working
table.
(2) Please DO NOT measuring home electricity (including two-phase
electricity and three-phase electricity).
(3) Please let the probe has 30 minutes rest after having a 5 minutes
normal measurement for over DC 10 KV or AC 7 KVRMS. It is
able to give time for internal high voltage resistors to cool down.

5. OPERATING PROCEDURE
!Connect to leads to the input and place the wire-grip on the
circuit to be tested.
!Connect the probe to the oscilloscope with the insulated
BNC/BNC lead.
!Adjust the vertical zero adjustment of the oscilloscope if
necessary.
!Select the attenuation ratio* and the vertical deviation of the
oscilloscope in accordance with the conversion table below.
!NB: The POWER light must come on.
The conversion table gives the real vertical deviation.

[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 500, the oscilloscope on 1 V/div, the
real vertical deviation is 500 x 1 V/div = 500 V/div.
With a 50 Ω load on the input of the oscilloscope the deviation
becomes: 500V/div x 2 = 1KV/div.
