Differential Voltage Probe,
Read the instructions before using the instrument:
1.Must acquire a differential voltage probe & get the best service from
instrument.
2.Read carefully the USER MANUAL.
3.Respect the safety precautions.
SAFETY PRECAUTIONS
Warning, Risk of Electric Shock,
Respect the max input voltages.
1.Max differential voltage: 15KV (DC + AC peak) or 5.5KV RMS
2.Max voltage between each input terminal and ground:7.5KV RMS
Do not use the probe in damp environment or where there is
risk of explosion.
Do not use the probe with its case open.
Disconnect the inputs and outputs of the probe before
opening the case.

FEATURES:
The DP-15K differential voltage probe provides a safety means of
measuring floating potentials for all models of oscilloscopes incomplete
safety.
It converts the high differential voltage (≦15 KV peak) into a low voltage
(≦8.0 V) with reference to the earth for display on the oscilloscopes.
The MAX. bandwidth is 75MHz, is suitable for big power testing and
research 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-15K is able to connect to DMM to observe directly. It is able to get
more accurate testing real value. (Oscilloscope accuracy is 3%, DMM
is about 10 times accuracy).
DP-15K is a design for high sensitivity module and high dynamic range.
Attenuation x 100, x 1000 is multiple of 10, which is easy for calculation
without mistake. Maximum voltage is 15KVp-p. It is a model designed
for ultra high voltage.
SPECIFICATIONS:
(1) Bandwidth:
DC - to 75 MHz (-3 dB) for x 100
DC - to 20 MHz (for attenuation x 1000)
(2) Attenuation: x 100, or x 1000
(3) Accuracy: ±2%
(4) Voltage Input Ranges (DC + AC peak to peak):
≦1.5 KVp-p for x 100, (i.e about 550 V RMS or ±750 V DC)
≦15 KVp-p for x 1000, (i.e about 5.5 KV RMS or ±7.5 KV DC)
(5) Permitted Max Input Voltage
Max differential voltage: 15 KV (DC + AC peak to peak)
Max voltage between each input terminal and ground: 7.5 KV RMS

(6) Input Impedance:
Differential: 54.4 MΩ// 1.5 pF
Between terminals and ground: 27.2 MΩ// 3 pF
(7) Output: ≦±8.0 V
(8) Output Impedance: 50 Ω
(9) Rise Time: 4.7 ns for x 100; 17.5 ns for x 1000
(10) Rejection Rate on Common Mode:
60 Hz: ＞80 dB ; 100 Hz: ＞60 dB ; 1 MHz: ＞50 dB
(11) Power Supply:
External 5 ~ 9 V DC power supply.
(12) Consumption: 200 mA about (5 ~ 9 V DC)

(2) Electrical Safety to IEC 1010-1:
Dual Insulation

Degree of Pollution 2
Rated Voltage or Max Live-Earth: 7.5 KV RMS
(3) CE Mark:
Conforms to EN 50081-1 and 50082-1 standards
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.
Attenuation X 1000 X 100
MAX Voltage Input Range(DC+AC Peak) 15 KV 1.5 KV
DC MAX INPUT ±7.5 KV ±750 V
AC RMS MAX INPUT 5.5 KV 550 V

Vertical Deviation
on the Oscilloscope
in V/div
Real Deviation In V/div
x 1000 Range x 100 Range
1 1000 100
0.5 500 50
0.2 200 20
0.1 100 10
50 m 50 5
20 m 20 2
10 m 10 1
5 m 5 0.5
2 m 2 0.2
[NOTE]
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 Ωload.
Example:
With the probe on factor x100, the oscilloscope on 0.5 V/div, the real
vertical deviation is 100 x 0.5 = 50 V/div.
With a 50Ωload on the input of the oscilloscope the deviation becomes
100 V/div.
