WARNING

Do not use DP-25 above 1000v ( DC + peak AC) between ground and the input or 1,300V ( DC + peak AC ) betweenthe input lead.
Do not operate DP-25 in wetor damp condition.
Do not operate DP-25 in anexplosive 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 bothPOWER and LOW BATT LED are not light.

FEATURES

TheDP-25 FET input differential probe provieds a safe means ofmeasuring circuits with floating potentials up to 1000 V ( DC+ peakAC ) from ground and 1300V ( DC + peak AC )differential.
TheDP-25 converts the high voltage differencial input signal to a lowvoltage ground refereced signal for display on anyOscilloscope.
Theoutput BNC of DP-25 is calibrted to drive a high impedance (1MΩ ) load.

INSTRUCTION FORUSE

Connect theoutput BNC of DP-25 to the input BNC of the Oscilloscope by theaccessory BNC cable.
Adjustthe vertical offset of the Oscilloscope ifnecessary.
Set theselect proper range of the DP-25 and the V / DIV of theOscilloscope according to the scale conversionchart.
Scaleconversion chart : The effective V / DIV is the attenuation factorof x 20, x 50, x 200 multiplied by the scale factor of theOscilloscope. It will be twice when the 50 Ωload was used. For example, withthe range set at x 200,
and the scope set to 0.5 V / DIV, the effective V / DIV equals 200x 0.5 or 100 V, with the 50 Ω load wasused, it becomes 200V, the power consumption will increasetoo.

NOTE: If the voltageof the input signal exceeeds the linear range of the settingrange.The signal output of the DP-25 would not accurately, the waveform display will be cut off.
