PRODUCT INTRODUCTION
The DP-5205A series differential voltage probes provide a safety means of measuring floating potentials for
all models of oscilloscopes incomplete safety.
It converts the high differential voltage (≦±1300 DC+AC peak) into a low voltage (≦±2.6 V) with reference
to the earth for display on the oscilloscopes.
The BNC output is designed to operate on an input with an impedance of 1 MΩ. It is 2 times of the 50Ω.
DP-5205A series are designed for high sensitivity modules and high dynamic range. Attenuation x50, x500
are multiple of 50, which is easy for calculation without mistake. Maximum voltage is 2.6 KVp-p. These are
designed for high voltage.

2. Connect the probe to the oscilloscope with the insulated BNC cable.
3. Adjust the vertical zero adjustment of the oscilloscope if necessary.
4. Select the attenuation ratio and the vertical deviation of the oscilloscope in accordance with the
conversion table1.
5. NB. The POWER light must come on.

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 X50, the oscilloscope on 0.5 V/div,
the real vertical deviation is 50 x 0.5 = 25 V/div.
With a 50 Ωload on the input of the oscilloscope the deviation becomes 50 V/div
Disconnecting from the Instrument
WARNING. To avoid electrical shock, disconnect the probe inputs from the circuit before
disconnecting the probe from the instrument.
1. Turn the probe connector counterclockwise.
2. Pull straight out.
Bandwidth Limit
Slide the Bandwidth limit switch to limit the probe bandwidth to 5 MHz. The 5 MHz filter assists in the
characterization and testing of power supplies in switch mode by removing all high frequency content, noise
and harmonics from the measurement.
Twisting the input leads
Twisting the input leads helps to cancel noise from high-EMI environments that is induced into the input leads.

External Power Source
Power consumption of the probe is about 500 mA,
thus it no suit for battery, please use the accessory
adapter only.
(Refer Figure4.)
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 VDC will caused to the
probe hard damage.

1. 將鉤夾 BP-256A (或鱷魚夾 BP-276N) 插入差動測試棒的輸入端引線，並將鉤夾 BP-256A (或鱷魚夾 BP-
276N)與測量電路接觸。
2. 將差動測試棒的輸出端接上 BNC 電纜後連結到示波器。
3. 如有需要先調整示波器上的垂直開關。
4. 將示波器上的衰減率及垂直開關調整到⼀致的位置，如表格 1. 所示。
5. 注意! 電源必須打開。

注意! 實際的垂直偏向是等於衰減乘上示波器上所選擇的垂直偏向，如果另外使用 50 Ω 負載
端子時，實際電壓值剛好是 2 倍量。
例如 :
測試棒是 X50, 示波器的垂直偏向在 0.5 V/div,
其實際的垂直偏向為 50 x 0.5 = 25 V/div
示波器輸入的負載是 50 Ω， 偏向就為 50 V/div
斷開與儀器連接
警告! 為避免電擊，在將測試棒與儀器斷開連接之前，請先將測試棒與電路斷開。
1. 逆時針轉動 BNC 接頭。
2. 直接拉出 BNC 接頭。.
頻寬限制
切換 Bandwidth Limit 開關，可以將輸出頻寬限制在 5 MHz。啟用頻寬過濾器後，可以有效去除所有的高頻內
容、諧振、 雜訊、簡化輸出波形。
輸入引線絞線
量測時將輸入線絞線，可以有效避免環境電磁干擾與雜訊。
