Maximum input Differential Voltage : 1300V ( DC + peak AC ) or 1000V RMS
Maximum input Voltage to Ground : 1000V ( DC + peak AC ) or 600V RMS
Common Mode Rejection Ratio ( CMRR ):
60Hz : >10,000 : 1
100Hz: >1,000 : 1
1MHz: > 300 : 1
Noise :≦ 2 mV rms ( Into 50Ω load )
Input Impedance :
2MΩ, 2.3 PF between inputs and ground.
4MΩ, 1.2 PF between inputs.
Power : external 6V-9V DC.
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.
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 ( 1MΩ ) 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 Ω 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.
