Mechanical zero point
(1) Allowable voltage variation ranges for 110V: 90~130V; for 220V: 180~260V.
(2) The mechanical zero point of the needle is the black point at the left end of the meter (see scale
example below).
(3) Please make sure to read the “Safety Precautions” (pp.5-8) and the “Selection Precautions” (p.9) to
assist in selecting the model and use specifications suited to the application.
Remarks
Note 1. For low-voltage circuits, grounding of
the secondary side of the instrument
voltage transformer is unnecessary.
