[name]: direct current MA meter [model]: 85C1 [Specification] 30mA  [dimensions]:: 64x56x60mm [parameter]: accuracy grade 2.5 basic error +-2.5% Damping response time: less than 4 seconds Pressure resistance: AC 50Hz, 2000V diachronic 1 minutes [instructions]: 85C1 DC A meter can be directly connected to the circuit in the circuit.   Use and application: This series of instruments is a direct analog display indicator instrument, measuring DC current, voltage, AC current, voltage, frequency, power factor, phase sequence, power, synchronization indication and other non electric measurement. It is widely used in all kinds of AC and DC transmission and distribution systems, power control screens and other electrical equipment in maritime ships, rail traffic, chemical explosion-proof, low voltage complete equipment, building equipment, generator sets, mechanical equipment and other industries. Applied to electrical measurement and non electrical measurement, it is suitable for medium and high grade instruments which are generally required by environmental conditions. Standards and certification: This series of pointer instruments are manufactured in accordance with GB/T7676-1998 and digital display meters according to GB/T22264-2008 standard, and their safety performance is produced according to GB4793 and IEC61010 standards.  The scale line and pointer design of the dial conform to the German DIN43790 and DIN43802 standards. The appearance and size of the instrument are manufactured according to GB/T1242 and IEC61554 standards. Sheet shell: The base is made of flame retardant TBT plastic, and the temperature of VEKA is 130 degrees. The shell is made of flame retardant ABS plastic, and the temperature of VEKA is 85 degrees. The amount of change caused by temperature: The reference temperature is 23 C + 2 C. The permitted temperature change is not greater than 100% of the grade index in the temperature range of 13 ~23 and 23 ~33. Installation position and installation method: Unless otherwise specified, the instrument is usually installed in a vertical position.  Other installation locations such as horizontal installation and tilt installation can be made according to customer requirements. The corresponding accuracy level is only valid for the specified installation location. The instrument is divided into 90 angles at right angles and 250 degrees wide angles, with two indication angles. Anti vibration and impact effects: Anti vibration: accord with IEC60068-2-6 standard; sweep frequency range: 10-55-10Hz; displacement amplitude: + 0.15mm, + 0.3mm. Frequency of sweeping cycles: 5 times; sweep rate: 10ct/min; maximum acceleration: 147m/s2 (15g), 490m/s2 (50g). The effective value of acceleration is 6.06g; the vibration time is 15min. Resistance to mechanical impact, in line with the IEC60068-2-27 standard. Accuracy grade: This pointer meter: AC and DC voltmeter and ammeter in level 1.5 or 2.5, the power meter is 2.5, the frequency meter is 2.5, and the power factor meter is 2.5. External current shunt shunt: Specifications for DC current meter external shunt voltage drop are 150mV, 100mV, 75mV, 60mV and 50mV, etc., which can be customized by users. The wire resistance between the instrument and the shunt is within 15 ~ 25m ohms, so as to ensure the accuracy of the instrument. Surface scale disc: Surface dial: aluminum alloy, white varnish, black ink printing or laser printing.  Customizable dial can be customized according to customers' samples. The noctilucent scale plate is made of PC board. Zero regulator: Except for the mechanical zero position reading meter, all the other instruments have zero position adjuster, which is used to adjust the zero position of instrument.
