INSTRUCTION MANUAL

DP-30K High Voltage Differential Probe

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: 30KV (DC + AC peak) or 11KV RMS
2. Max voltage between each input terminal and ground: 10KV 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-30K differential voltage probe provides a safety means of measuring floating potentials for all models of oscilloscopes incomplete safety.

• It converts the high differential voltage (≦ 30 KV peak) into a low voltage ( ≦ 8.0V) with reference to the earth for display on the oscilloscopes. (MAX. Bandwidth: 75 MHz)

• The BNC output is designed to operate on an input with an impedance of 1 MΩ. It is 2 times of the 50 Ω.

• From DMM can observe more exact measured testing voltage.
  (Oscilloscope accuracy is 3%, and DMM is 10 times).

• DP-30K is a design for high sensitivity module and high dynamic range.

   ≦ 30 KVp-p for x 2000, (i.e about 11 KV RMS or ± 15 KV DC)

5. Permitted Max Input Voltage
   Max differential voltage: 30 KV (DC + AC peak to peak) ± 15 KV DC
   Max voltage between each input terminal and ground: 10 KV RMS

6. Input Impedance:
   Differential: 81.6 MΩ // 1 pF
   Between terminals and ground: 40.8 MΩ // 2 pF

7. Output: ≦ ± 8.0 V

8. Output Impedance: 50 Ω

9. Rise Time: 4.7 ns for x 200; 17.5 ns for x 2000

10. Rejection Rate on Common Mode:

11. Power Supply:
    External 5 V DC power supply.

12. Consumption: 0.5 A / 5 V DC

CAUTION!

1. Please DO NOT hold the probe itself when measuring the high voltage is over 1kV. 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 10kV or AC 7kVRMS.
   It is able to give time for internal high voltage resistors to cool down.

PANEL DESCRIPTION:

OPERATING ENVIRONMENTAL CONDITIONS:

| Reference| Use| Storage
---|---|---|---
Temperature| +20°C …+30°C| 0°C …+50°C| -30°C …+70°C
Relative Humidity| ≦ 70 % RH| 10 % … 85 % RH| 10 % …90 % RH

1. Dimensions and Weight: 220 x 85 x 30 mm; 350 g

2. Electrical Safety to IEC 1010-1:
   • Dual Insulation
   • Installation Category III
   • Degree of Pollution 2
   • Rated Voltage or Max Live-Earth: 10 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.

Real Deviation In V/div
---|---
X 2000 Range| X 200 Range
1| 2000| 200
0.5| 1000| 100
0.2| 400| 40
0.1| 200| 20
50 m| 100| 10
20 m| 40| 40
10 m| 20| 20
5 m| 10| 1
2 m| 4| 0.4

[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 Ω load.

Example:
With the probe on factor x200, the oscilloscope on 0.5 V/div, the real vertical deviation is 200 x 0.5 = 100 V/div.
With a 50 Ω load on the input of the oscilloscope the deviation becomes 100 V/div.

EXT. POWER SOURCE:

• Power consumption of the probe is about 0.5 A, please use the company provided adaptor with current (positive and negative) polarity.
• If there are any damage on the adaptor, please contact us and use the adaptor supply by us only. If the input power over 12 V DC will caused to the probe hard damage.
