Connect the shunt to the wires on the earth side.. See P.9 for details on the outside dimensions of the shunt. Instrument Lead Instrument lead is not included. Instrument Lead Resistance. Meters externally attached to shunts are normally adjusted to an instrument lead resistance of 0.0Ω. (Indicate LEAD 0.0Ω on the scale plate) Therefore, use wiring that is equivalent to 0.0Ω for the instrument lead.. Please provide separate instructions if the instrument lead resistance is to be a value other than 0.0Ω. When combining with a 60mV rated shunt, the instrument lead resistance can be manufactured up to.0ω specifications. If the wiring exceeds.0ω, combine with a high mv shunt.. If the instrument lead resistance is not clearly specified, the meter can be manufactured with a sensitivity adjustment variable resistor (VR). The adjustable range is up to.0ω for a 60mV meter. ) The model name of an meter equipped with VR is the same as the normal model name with V appended. E.g.

18 Wattmeter, Factor Meter Misconnection Phenomena When using a measuring circuit with VT, CT for wattmeters, power factor meters, etc., a complete review will often show that misconnection due to the location where installation is applied is often the cause of indicating meter failure. There is only one kind of correct connection, but there are many cases which result in misconnection. Reference the figures below for examples of particularly common examples of misconnection phenomena. (Correctly connect phase sequence and polarity. Set phase rotation to an order of...

24 Notice for New JIS Mark Products Meters bearing the new JIS mark are guaranteed for use in the conditions described below. Adhere to the following precautionary conditions when installing meters. The following are general conditions for the installation environment of meters. () Use in an indoor environment () Measurement category of the measurement circuit: III () Pollution level: (4) Installation height: 000m or lower () Temperature range: from to 40 C (6) Highest relative humidity until C: 80%. At 40 C it should be directly reduced to a general humidity of 0% The following installation conditions are in accordance with provisions JIS C 0-:007 (direct acting electrical indicating instrument) and JIS C 00-:00 (Safety requirements for electrical equipment for measurement, control, and laboratory use ). (Although products that operate in environments comprising of a wide variety of humidity and temperature can be found in our company s catalog, the acceptable range of temperature and humidity for safe usage is as prescribed above.) In order to assess compatibility requirements for the security of panel attachments for meters, assessments are made assuming the user is standing in front of the attached panel. For this reason, the inside of installed panels (parts of distribution boards, etc.) are excluded from general maintenance because it is assumed they are only handled by persons who have specialized knowledge. When installing panels for meters, make sure internal parts cannot be touched by general users. Furthermore, product fuses should be installed by a person who has undergone sufficient training, and the necessary consideration should be given to safety such as inserting fuses into voltage circuits.

25 Precautions for Handling Meters Be sure to note the following when handling the meter. (60 or over) because the plastic cover and base of the meter are easily affected by heat. The following points apply to the anti-static finish that has been applied to the transparent part of the cover. ) Remove dirt from the surface of the cover by gently wiping it with a damp towel or leather. ) Do not use alcohol, paint thinner, benzine or other such liquids that contain these chemicals to wipe the surface of the cover. (Doing so damages the coating, reducing its effectiveness.) ) Do not use polishing silicone, silicone cloth, or any other silicone-based cleaning agent to clean the surface of the cover. (Doing so reduces the effectiveness of the water-resistant finish.) 4) Do not store the meter by wrapping it in newspaper or other paper products. (Wrapping products in a hygroscopic material causes faster degradation.) Do not apply solder directly to meter terminals. Also, be sure not to solder the case when soldering connections. 4 PThinneraintl60 BAlcoho The case may be damaged through contact with chemicals (paint thinner, benzine, alcohol, etc.). Apply a commercially available antistatic agent if the antistatic agent has peeled or is no longer effective. If the anti-static agent has peeled or is no longer effective, even the slightest touch can cause the indicator to move, resulting in incorrect readings. The effectiveness of the anti-static finish may be negatively affected when the humidity is particularly low, such as during the dry periods in winter. The following anti-static agents can be applied easily. Riverson No. 0 with applicator (made by Tokyo Yakuhin Kakosei) Anti-Sta #80S spray-type (made by Tanaka Chemical Laboratory) enzine Avoid high temperature locations
