Remarks
(1) Refer to the “Wattmeter Scale Selection Reference Table” (p.54) concerning the manufacturable
maximum scale value of a wattmeter relay.
(2) The varmeter relays are bidirectional deflection indicators with “Zero” as the central division and with
LEAD at the left side and LAG at the right side. Refer to the “Varmeter Scale Selection Reference
Table” (p.60) concerning the manufacturable maximum scale value of a varmeter relay.
(3) Unidirectional deflection indicators can also be manufactured for varmeter relays. Please specify
LEAD or LAG (standard is LAG).
(4) 1A current rating models are also manufactured (the consumption VA is similar to that of a 5A model).
(5) The T-150 rectifier is a dedicated accessory (non-compatible accessory) and thus cannot be used in
combinations besides those specified for the indicators. The distance between the indicator and the
T-150 rectifier must be 5m or less or the round trip lead wire resistance must be 0.5Ω or less.
(6) The weight of the T-150 rectifier is approximately 1kg.
(7) 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.
