Wattmeters Time intervals: 2 and 15 minutes
The electricity demand, instantaneous electricity and maximum electricity demand can be
recorded. In addition, wattmeters can be used to monitor transformer load and electricity.
Receiving indicators Time intervals: 2 and 15 minutes
Receiving indicators are used in combination with various electrical transducers or
instrumentation transducers, such as those for measuring temperature, to perform telemeter
measurements (remote measurement).

Remarks
(1) Refer to the “Wattmeter Scale Selection Reference Table” (p.56) regarding the manufacturable
maximum scale value of a wattmeter.
(2) The T-150 rectifier and T-150LB DC amplifier are dedicated accessories (non-compatible). They can
only be used in combination with the indicators specified. The distance between the indicator and the
T-150LB DC amplifier/T-150 rectifier must be 5m or less, or the round trip lead wire resistance must
be 0.5Ω or less.
(3) Wattmeters cannot be manufactured with both positive and negative readings on the scale.
For receiving indicators with a positive/negative scale, use a transducer to convert positive/negative input to positive output (e.g., convert input of -1,000 to
0 to +1,000W to output of 0 to 0.5 to 1mA).
(4) For scales that measure in electrical units (A, V, W, var, cosø, Hz), AC/DC and three-phase circuit symbols are not displayed. For receiving indicators, the
symbol for the quantity to be input is displayed.
(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.
