Description
80*65mm ac dc ammeter
The installation:
Unless specified, the meter is usually installed in a vertical position. Other installation positions such as horizontal and inclined position can be installed according to the customer's requirements. The corresponding level of accuracy is only valid to the regulated installation position. The meter has two kinds of instruction angles: Right angle 90° And wide angle 250° .
Anti-vibration and anti-shock:
Anti-vibration: Complies with the standard of IEC60068-2-6; Frequency sweep range: 10-55-10Hz; Displacement amplitude: ± 0.15mm, ± 0.3mm; Frequency sweep cycles: 5 times; Sweep rate: 10ct/min; Maximum acceleration: 147m/s2(15g), 490m/s2(50g); RMS acceleration: 6.06g; Vibration time: 15 min. Anti mechanical shock: Complies with the standard of IEC60068-2-27.
Accuracy level:
The JY series of pointer meter: AC and DC voltmeter and ammeter to the level of 1.5 or 2.5, power meter to the level of 2.5, frequency meter to the level of 2.5, and power factor meter to the level of 2.5.
Overload ammeter:
The conventional overload multiple times should be once or twice, and it can be customized to once, twice, 3 times and so on according to the user's requirements. Its function is to indicate the approximate transient overload current value, such as the start-up current when the motor stars, and so on.
Extrinsic current shunt:
The voltage specifications of the extrinsic current shunt of DC ammeters are 150mV, 100mV, 75mV, 60mV and 50mV, which can be customized. The resistance of the conducting wire connecting the meter and the current shunt should within the range of 1525mΩ , to ensure the accuracy of the meter.
