一、簡述：
UT-P33 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(≤14KVPEAK)進入一個低電壓(≤7V)， 並且顯示
波形在示波器上，使用頻率高達 120MHz，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-P33 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-P33 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

UT-P33
(1) Features
The UT-P33 differential probe provides a safety
means for measuring differential voltage to all
models of oscilloscopes.It can convert the high
differential voltage(≤14KVp-p) into a low
voltage(≤7V)and display on the oscilloscope.Its
bandwidth is up to 120MHz,which is ideal for big
power testing,development and maintain.
The UT-P33 is designed to operate with the 1MΩ
impedance oscilloscopes. When combine with the
50Ω load , the attenuation will be 2 times.
UT-P33 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 DMM is less than 1%)

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.
