Features-11M

1. A long scale meter for indicating wide
angles.
2. A stepped scale plate is used to remove anylevel difference between the scale and tip ofthe needle, resulting in accurate readings.

Details of Changes from Previous Product (□VF-11 Series)

3. Meter that has a bright scale due to thewide cover lighting surface.

1. Mounting screws at the four corners of the meterchanged from M6 to M5 size.
2. Meter terminal screws changed as follows.
Ammeter, voltmeter, frequency meterM6 screws  M4 screws
Wattmeter, Varmeter, Power Factor Meter

Sensitivity:
Approx. 10mA

1. Meters externally attached to shunts are normally adjusted to an
instrument lead resistance of 0.05Ω.
(Indicate LEAD 0.05Ω on the scale plate)
Therefore, use wiring that is equivalent to 0.05Ω for the instrument
lead.
2. Please provide separate instructions if the instrument lead resistanceis to be a value other than 0.05Ω.
When combining with a 60mV rated shunt, the instrument leadresistance can be manufactured up to 1.0Ω specifications.
If the wiring exceeds 1.0Ω, combine with a high mV shunt.
3. If the instrument lead resistance is not clearly specified, the meter canbe manufactured with a sensitivity adjustment variable resistor (VR).
The adjustable range is up to 1.0Ω for a 60mV meter.

1. Use combined CT and 5A (1A) meter if 10A is
exceeded.
2. When circuit voltage of 600V is exceeded at
10A or below, use combined CT and 5A (1A)
meter for insulation.

Extended Scale Meter

Approx.

Use a double, triple or five-times extended scale
meter-standard meter to measure the current
flow of electric motor-class of starting current.
Usage example For a triple extended scale
AVF-11M
0~100~(300)A(CT ratio 100A/5A)

Use combination of
CT and 5A (1A) meter.

Note

WeightNote 1) In the case of extended scale meters, the 70% pointon the scale length represents the measurement
range (upper limit value of the effective
measurement range), and the section that exceeds
70% up to 100% is the extended scale section.
(Extended scale part intrinsic error: ±10% of
indicated values)
Note 2) The red color extended scale lines are the points
below for extended scale meters.

Note 1) The standard scale meters and extended scale meters shown below are standard
specification displays.

Conducted via sine waves.
For direct feed type telemetering, you can reduce line loss if the second rated value uses a 1A
CT combined with a 1A meter. (The rated value of 5A is 1/25.)
To further reduce loss, use an AC current transducer combined with a DC meter.
(For details on AC current transducers, see the AC current transducer catalog.)

Using the Above Chart[1] For 3P wattmeters, 3P4W wattmeters, and 1P3W wattmeters, the measurement range upper limit values are displayed in thevoltage ratios (VT ratio differences) and CT ratio differences in the table above. (There are three types defined for the same VT andCT ratios. Choose the appropriate type.)(E.g.) For a VT: 3300V/110V, CT: 100A/5A 3P wattmeter... select the appropriate one from 400kW, 500kW or 600kW from the table above.
[2] For 1P wattmeters, 3P varmeters, and 3P4W varmeters, the values displayed above are multiplied by 1/2, and are multiplied by 1/4

500A/5A row (2 MW, 2.5 MW, 3 MW) and multiply it by 10.
Note) In the situation above, scale indicators are 20MW, 25MW and 30MW. (It is preferable that the highest 3 digits of scales are displayed)[4] If CT ratios do not correspond with those indicated above (for example, CT: 60A/5A), use the calculation chart below to acquire themeasurement range, then choose from among them the value with the best ending number.
Measurement Range Value = Intrinsic Power × VT Ratio × CT Ratio
Note) Select a value indicated below from the intrinsic power value in the above calculation chart. However, intrinsic power
values vary depending on meter type. Use the multiplier indicated below to calculate the value.

E.g. For a VT3300V/110V, CT: 60A/5A 3P wattmeter
Measurement Range Value = (667W, 833W, 1kW or 1.11kW) × 3300/110 × 60 / 5= 240kW, 300kW, 360kW or 400kW.

[5] Values of 1, 1.2, 1.5, 2, 2.5, 3, 4, 5, 6, 7.5 or 8, or integers that are multiples of those 10 values are preferable selections for theupper range scale value. (JIS standards)

[6] Even when using a CT of 1A for the secondary current, the measurement range value is as indicated on the left (selection standards
chart).
Note) If CT ratios do not correspond (for example, CT: 60A/1A) with those indicated to the left (selection standards chart),
follow calculation chart [4] below to calculate the measurement range value. However, intrinsic power values varydepending on meter type. Use the multiplier indicated below to calculate the value.

Production Limits of Meters (Wattmeter, Varmeter)
The production range of wattmeters and varmeters can be manufactured according to the indicated range of intrinsic power values in
the calculation chart below.

Wattmeter, Power 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 particularlycommon examples of misconnection phenomena.
(Correctly connect phase sequence and polarity. Set phase rotation to an order of 1.2.3. Three-phase unbalanced power factor meters
will be particularly inoperable.)

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.
(1) Use in an indoor environment(2) Measurement category of the measurement circuit: III(3) Pollution level: 2(4) Installation height: 2000m or lower(5) Temperature range: from 5 to 40°C
(6) Highest relative humidity until 31°C: 80%. At 40°C it should be directly reduced to a general humidity of
50%
The following installation conditions are in accordance with provisions JIS C 1102-1:2007 (direct acting
electrical indicating instrument) and JIS C 1010-1:2005 (Safety requirements for electrical equipment formeasurement, 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, theacceptable 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 thenecessary consideration should be given to safety such as inserting fuses into voltage circuits.

23

Precautions for Handling Meters
Be sure to note the following when handling the meter.

● The following points apply to the anti-static finish that has been
applied to the transparent part of the cover.
1) Remove dirt from the surface of the cover by gently wiping itwith a damp towel or leather.
2) Do not use alcohol, paint thinner, benzine or other such liquids
that contain these chemicals to wipe the surface of the cover.

Benzine● Do not apply solder directly tometer terminals.
Also, be sure not to solder the casewhen soldering connections.

Alcohol● Avoid high temperature locations(60℃ or over) because the plastic
cover and base of the meter are
easily affected by heat.

Paint

Thinner

˚

60● The case may be damaged throughcontact with chemicals (paintthinner, benzine, alcohol, etc.).

● Apply a commercially available antistatic agent if theantistatic agent has peeled or is no longer effective.

If the anti-static agent has peeled or is no longer effective, even theslightest 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.

(Doing so damages the coating, reducing its effectiveness.)3) Do not use polishing silicone, silicone cloth, or any othersilicone-based cleaning agent to clean the surface of the cover.

● The following anti-static agents can be applied easily.
 Riverson No. 30 with applicator (made by Tokyo Yakuhin
Kakosei) Anti-Sta #80S spray-type (made by Tanaka Chemical
Laboratory)(Doing so reduces the effectiveness of the water-resistant finish.)
