Product parameters
| Parameter | Details |
|---|---|
| Composition of structural materials | Transparent PC cover, bakelite base, semi transparent cover can be customized according to requirements |
| Pointer | The standard instrument pointer is made of aluminum alloy. The black, red and white pointers can be customized according to customer requirements. The setting pointer can be added to indicate the anti-static treatment of the set value: all instruments are subject to anti-static treatment to reduce the impact of static electricity on the accuracy of the instrument. |
| Damping and overshoot | Damping and overshoot can be customized according to customer requirements. Generally, when the pointer is set at 2/3 of the full scale, the overshoot does not exceed 15%. |
| Accuracy class | General: Class 1.5/2.5 Others: can be customized according to the user's accuracy requirements |
| working temperature | -20 ~ +50 °C |
| Installation position | Unless otherwise specified, the instrument is normally installed in a vertical position |
| Other locations | Horizontal/inclined installation can be customized according to customer requirements. The corresponding accuracy level is only valid for the specified installation position. Voltage drop specifications of external shunt: voltage drop specifications of external shunt of DC ammeter include 150mV, 100mV, 75mV, 60mV, 50mV, etc. The resistance of the wire connecting the instrument and the shunt is required to be 15-25m Ω. |
