Use the recommended digital multimeter or commercially available digital multimeter with an impedance of 10 MΩ/DCV minimum.
The display value differs depending upon the internal impedance of the multimeter.
Connect the peak voltage adapter to the digital multimeter.
- Peak voltage tester (U.S.A, only) or
- Peak voltage adapter 07HGJ-0020100
- with Commercially available digital multimeter (impedance 10 MΩ/DCV minimum)
