Oscilloscope UT-P33 Differential Probe Active Probe Instruction Manual

Oscilloscope UT-P33 Differential Probe Active Probe

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%)

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.

Voltage Input Range

(DC+AC Peak to PEAK)

| 14KV| 1.4KV

[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.
