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 ?[ 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.
