15 Voltage Measurement and Waveform Chart
Note:
·
Indicated voltage values are the standard values for the unit measured by the DC electronic circuit tester (high-impedance)
with the chassis taken as standard.
Therefore, there may exist some errors in the voltage values, depending on the internal impedance of the DC circuit tester.
·
Circuit voltage and waveform described herein shall be regarded as reference information when probing defect point
because it may differ from actual measuring value due to difference of Measuring instrument and its measuring condition
and product itself.
