Uses and applications:
This AOYI series of meters is a direct imitation of power measurement display instruments, measuring DC current and voltage, AC
current and voltage, frequency, power factor, phase sequence, power, synchronization instructions and other non-power
measurements. It has been widely used in a variety of AC and DC transmission and distribution systems, power control panels and
other electrical devices, in the industries of maritime shipping, rail transport, chemical flameproof, low voltage equipment,
construction equipment, generators, machinery equipment, etc. Being able to make electrical measurement and non-power measurement it is a high-end instrument applied in general environmental conditions.

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°.
Accuracy level:
The AOYI 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.
Benefits of the product (the dial can be replaced):
For the AOYI series of pointer meter, you can open the sealing, insert or outer the dial. As for the AC ammeter, as long as the secondary current of the transformer is the same, you can replace the dial with the accuracy unchanged. As for the DC ammeter, as long as the shunt output signal or the meter input signal is the same, you can replace the dial even if the meter is of different specifications, with the accuracy unchanged.
