Remarks
Note 1.
(1) If, with a maximum scale of 600V or less, an externally mounted multiplier is desired, the voltmeter
will be manufactured with the GR-2 multiplier as an accessory.
(2) Indicators with both positive and negative readings on the scale can be manufactured if the larger of
the left and right scales is 2000V or less.
The table above shows whether or not a multiplier is provided.
(3) If a high sensitivity (high input resistance) indicator is desired as a DC voltmeter with a maximum
scale of 100V or less, please specify the maximum scale and sensitivity current of the indicator.
Voltmeters can be manufactured with a sensitivity current within the range shown for DC ammeters
on p.45.
There may be a maximum difference of approximately ±5% with respect to the value specified for the
sensitivity current.
(4) The GR-2 and KR-1 multipliers are dedicated accessories (non-compatible). They can only be used in
combination with the indicators specified.
(5) 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.
These voltmeters do not have a JIS mark.
