WARNING

1. Do not use AD25 above 1000v ( DC + peak AC ) between ground and the input or 1,300V ( DC + peak AC ) between the input lead.
2. Do not operate AD25 in wet or damp condition.
3. Do not operate AD25 in an explosive atmosphere.
4. Do not immerse AD25 in liquids.
5. Do not operated AD25 without covers.
6. Please change the battery when the "LOW BATT " LED is lighted. At this time AD25 can operate but not guaranteed the accuracy.
7. AD25 can not operate if both POWER and LOW BATT LED are not light.

FEATURES

1. The AD25 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.
2. The AD25 converts the high voltage differencial input signal to a low voltage ground refereced signal for display on any Oscilloscope.
3. The output BNC of AD25 is calibrted to drive a high impedance ( 1MΩ ) load.

INSTRUCTION FOR USE

1. Connect the output BNC of AD25 to the input BNC of the Oscilloscope by the accessory BNC cable.
2. Adjust the vertical offset of the Oscilloscope if necessary.
3. Set the select proper range of the AD25 and the V / DIV of the Oscilloscope according to the scale conversion chart.
4. 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 AD25 would not accurately, the wave form display will be cut off.
