操作 (OPERATION)
Connect the plugs to the volts ( Hi ) & com ( Lo ) input terminals of your voltmeter ( or Multimeter ). Select the desired range of voltmeter ( Attention : Do not use auto ranging ).
Whenever possible, turn the high voltage source off before making any connections. Connect the HV probe common lead ( alligator clip ) to a good earth ground or reliable chassis ground.
安全預防措施和警告 (SAFETY PRECAUTION & WARNING !!!)
* This high voltage probe must be used by the person who are trained only. Do not work alone when working with high voltage circuits & environment.
* For your own safety, inspect the probes for cracks & frayed or broken leads before each use. If any defects are noted, do not use the probes.
* Hands, shoes, floor & work bench must be dry. Avoid making measurements under humid, damp or other environmental conditions that might affect the safety of measurement situation.
* The ground connection must always be made before the probe tip comes into contact with the high voltage & must not be removed until after the probe tip has been removed from high voltage source.
* Do not attempt to take measurement from sources where the chassis or return lead is not ground.
* If possible, always turn the high voltage source off before connecting or disconnecting the probe.
* Before turning the high voltage on, make sure that no part of your body is in contact with the device under test.
* The probe body should be kept clean & free of any conductive contamination. Clean only the exterior probe body & cables. Use a soft cotton cloth lightly moistened with a mild solution of detergent & water. Do not allow any portion of the probe to be submerged at any time.
