FEATURES
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.
