一、簡述：
UT-P31差動測試棒提供一個安全的儀器給所
有的示波器使用，它可以轉換由高輸入的差動
電壓(≤1500VPEAK)進入 一個低電壓(≤7V) ，並
且顯示波形在示波器上，使用頻率達 100MHz，
非常適合大電力測試、研發、維修使用。
差動測試棒輸出標示是設計在操作示波器
1MΩ的輸入阻抗的相對衰減量，當使用 50Ω匹
配器進衰減量剛好爲 2倍量。 UT-P31 差動測試
棒，也建議選購本公司生産的 PL-10 阻抗轉換
器，可以延伸差動測試棒的應用範圍-可以在
電錶上觀測更精確的實際測量電壓值(示波器
精確度爲 1%，數位電錶約精准 10倍)。

四、操作程式
將BP-250 與UT-P31 的輸出端連接，並與示波
器連結。
如有需要先調整示波器上的垂直開關。
將示波器上的衰減率及垂直開關調整到一致的
位置，如下表。
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，例如是使
用負載50Ω的兩倍。
五、維護
保養此産品時請使用原廠指定的工具，原廠將
不負任何責任由其他 不被認可的維修人員所
做的維修。

UT-P31
1.Features
The UT-P31 differential probe provides a safety
means for measuring differential voltage to all
models of oscilloscopes.It can convert the high
differential voltage(≤1500Vp-p) into a low
voltage(≤7V)and display on the oscilloscope.Its
bandwidth is up to 100MHz,which is ideal for big
power testing,development and maintain.
The UT-P31 is designed to operate with the 1MΩ
impedance oscilloscopes. When combine with the
50Ω load , the attenuation will be 2 times.
UT-P31 is recommend to use with our own
manufactured PL-10 to expand the measuring with
the electricity meter to observe more accurate
measurement.The accuracy of oscilloscope is 1%
and the electricity meter is about 10 times)

4.Operating procedure
․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.
[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.
▉Maintenance
For maintenance,only use specified spare
parts.The manufacturer can not be held
responsible for any accident arising following a
repair made other than its after sales service or
approved repairs.
▉Cleaning
This probe does not require any particular
cleaning.If necessary,clean the case with a cloth
slightly moistened with the soapy water.
