7514 Voltage and Waveform Measurement14.1. Voltage MeasurementNote:• Indication Voltage Values are in standard values for the unit measured by the DC electronic circuit tester (high-impedance) withthe chassis taken as standard.Therefore, there may exist some errors in 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 itmay differ from actual measuring value due to difference of Measuring instrument and its measuring condition and product itself.14.1.1.
