Instructions

Use and application:

Voltage, AC current, voltage, frequency, power factor, phase sequence, power, synchronous indication and other non-electrical measurement.Many used in maritime ships, rail transit , Chemical explosion-proof, low-voltage equipment, construction equipment, generating units, machinery and equipment industries AC and DC transmission and distribution systems, power control panel and other electrical equipment.Effective measurement and non-electrical measurement is applicable General requirements in the environmental conditions are more general in the high-end instruments.

Standards and Certification:

The instrument is in accordance with GB / T7676-1998, digital instrument is in accordance with GB / T22264-2008 standard production, the safety performance in accordance with GB4793 and IEC61010 standard production. Dial scale and pointer design in line with the German DIN43790 and DIN43802 standard. Meter shape and hole size in accordance with GB / T1242 and IEC61554 standard production. Elite Instrument Electric Company all products through the national CE certification, and access to IS0; 9001 certification.

Table shell side:

JY series The base is flame retardant TBT Made of plastic, Vicat temperature of 130 ℃. shell Made of flame-retardant ABS plastic, Vicat temperature 85 ℃.

Temperature-induced changes in the amount of:

Reference temperature is 23 ℃ ± 2 ℃ .13 ℃ ~ 23 ℃ and 23 ℃ ~ 33 ℃ temperature range, the temperature change is not allowed to change the level index of ± 100%.

Installation location and installation methods:

Unless otherwise specified, the instrument is normally mounted in a vertical position Other installation positions such as horizontal installation and tilting installation can be made according to customer requirements The corresponding accuracy level is valid only for the specified installation position The instrument at right angles 90 ° and wide angle 250 °, two kinds of indication angle.

Anti-vibration and impact of impact:

Anti-vibration : In accordance with IEC60068-2-6 standard; sweep frequency range: 10-55-10Hz; displacement amplitude: ± 0.15mm, ± 0.3mm.

Sweep frequency: 10ct / min; maximum acceleration: 147m / s2 (15g), 490m / s2 (50g).

Vibration time: 15min. Anti-mechanical shock, in line with IEC60068-2-27 standard.

Accuracy level:

JY series Pointer instruments: AC and DC voltmeter and ammeter in 1.5 or 2.5, power meter 2.5Level, the frequency table 2.5Level, power factor meter for the 2.5 level.

Overload ammeter aspects:

Overload times conventional 1 times and 2 times the overload factor, can be customized to 1 times the user requirements, 23 times, etc. Its role is to indicate the approximate value of instantaneous overload current, such as the start-up current when the motor starts.

External current shunt side:

DC ammeter external shunt voltage drop specifications 150mV, 100mV, 75mV, 60mV and 50mV, etc. can be customized by the user requirements. Instrument and shunt connection wire resistance requirements in 15~25mΩ, To ensure instrument accuracy.

Surface Dial:

surface Dial: aluminum alloy material, white paint, black ink printing or laser printing printing. Can be customized according to customer-like dial (customizable variety of color overprint.) Luminometer dial with PC board.

Zero adjuster aspect:

In addition to no mechanical zero reading meter, all the rest of the instrument are pre-zero position regulator, used to adjust the instrument mechanical zero.
