25MHz High Voltage Differential Probe for oscilloscope

 

 facebook
Product ID: DP-25

. The DP-25 High Voltage Differential probe provides a safety means for measuring differential voltage to all models of oscilloscope.  The DP-25 coverts the high differential voltage (<=1400 Vpeak) into a low voltage (<=7.0v, with reference to the earth) and display on the oscilloscopes.  The DP-25 is designed to operate with the 1M Ohm impedance oscilloscope. When combine with the 50 Ohm load, the attenuation will be 2 times. We recommend to use Tecpel PL-10 with DP-25 to expand the measuring with Digital multimeter (DMM) to observe more accurate measurement. The accuracy of oscilloscope is 3% and the DMM is less than 1%. Note: If you connect DP-25 to the DMM without Tecpel PL-10 the accuracy will be higher than 10%.

Specifications:
  • FEATURES
    •  The DP-25 FET input differential probe provieds a safe means of measuring circuits with floating potentials up to 1000 V ( DC+ peak AC ) from ground and 1300V ( DC + peak AC ) differential.
    • The DP-25 converts the high voltage differencial input signal to a low voltage ground refereced signal for display on any Oscilloscope.
    • The output BNC of DP-25 is calibrted to drive a high impedance ( 1M Ohm) load.
    • INSTRUCTION FOR USE
    • Connect the output BNC of DP-25 to the input BNC of the Oscilloscope by the accessory BNC cable.
    • Adjust the vertical offset of the Oscilloscope if necessary.
    • Set the select proper range of the DP-25 and the V / DIV of the Oscilloscope according to the scale conversion chart.
    • Scale conversion chart : The effective V / DIV is the attenuation factor of x 20, x 50, x 200 multiplied by the scale factor of the Oscilloscope. It will be twice when the 50 Ω load was used. For example, with the range set at x 200,
    • and the scope set to 0.5 V / DIV, the effective V / DIV equals 200 x 0.5 or 100 V, with the 50 Ohm load was used, it becomes 200V, the power consumption will increase too.
    • NOTE:If the voltage of the input signal exceeeds the linear range of the setting range.The signal output of
    • the DP-25 would not accurately, the wave form display will be cut off.
  • WARNING
    • WARNING
    • Do not use DP-25 above 1000v ( DC + peak AC ) between ground and the input or 1,300V ( DC + peak AC ) between the input lead.
    • Do not operate DP-25 in wet or damp condition.
    • Do not operate DP-25 in an explosive atmosphere.
    • Do not immerse DP-25 in liquids.
    • Do not operated DP-25 without covers.
    • Please change the battery when the "LOW BATT " LED is lighted. At this time DP-25 can operate but not guaranteed the accuracy.
    • DP-25 can not operate if both POWER and LOW BATT LED are not light.
