High Voltage Probe HV-P60A

 

 

 

4.2 Measuring Procedure

 

   

(1) Confirm that the voltage of the object to be measured is within 

the range of the measurement of this instrument. 

   

(2) Confirm that there is neither person in surroundings nor 

something that touches. 

   

(3) The power supply of the object to be measured is turned on, 

and the measurement begins. 

   

 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

Note

 

 

 

When measuring, ringing and the overshoot might be   
caused. In addition, it is necessary to strengthen GND in   
addition to the earth lead of the attachment to decrease ringing   
and the overshoot. Prepare the metal with high electric   
conductivity (treatment device), tie to the earth lead joint, and   
strengthen GND.

 

In that case, do not touch the probe point with   

GND.

 

As a concrete example, there are the following methods of etc. 

 

(1) The stick made of copper (about φ5 mm) is used. 

(2) The thin sheet copper is folded and used. 

Example) The thin sheet copper plate of the width of 50mm is 

folded four times, and it is used by the width of 10mm. 

      * However, use together or substitute the earth lead of the   

attachment if necessary when you use the above-mentioned 

treatment device.
