2. Specification of ammeter for transformation ratio:the meters should be used with a current transformer of 

which primary current is *0A *5A *0A *5A *0A *0A *0A *0A *5A **0A **0A **0A...*0KA and external 

secondary current 1A or 5A.As long as overload rate and the incoming current keep the same,dial scales 

of all types in this series can be exchanged ye remain the accuracy.

 

3.Overload rate of ammeters:1. non-overload 2. 1.2times 3. 2times  4. 5times.

**0V **0V.

5.Specification of voltmeters for transformation ratio:The meters should be used with a voltage transformer of 

which primary voltage is **0V **0V **0V **0V ***0V ***0V ***0V ***0V ***0V...**0KV and external 

secondary voltage **0V.

 

6.Overload rate of voltmeters:1.non-overload  2. 1.2times.

 

7.Product performance:all the meters are equipped with pure white silk- screen printing dial scale.The movement is made of intensive PBT plastics and high-performance magnetic materials so that it is vibration-resistant and heat-resistant.The case is made of ordinary ABS plastics of flame retardant ABS plastics,of which the resistant

 temperature can be up to *5°C.The base is made of PC plastics or flame retardant PC plastics,of 

which the resistant temperature can be up to **0°C.The resistant voltage is higher than ***0V.

The resistant voltage is higher than ***0V.This kind of meter is easy to install with high-strengthen plastics grip piece by screwing down the nut so that the meter is of high immobility.

 

8.Principles of measurement and the features:Each electromagnetic meter consists of a magnet 

coil with a static sheet iron inside and a moving sheet iron with a tractive balance spring.

When current flows through the magnet coil,magnetic field appears.Under such circumstance,the 

static and the moving sheet irons are magnetized simultaneously and remain the same polarity.

According to the theory that the same polarities repel each other,repulsive force between the two 

irons makes the pointer deflect.When the torque and the restoring torque keep a balance,the static 

and the moving sheet irons are magnetized simultaneously and remain the same polarity.

According to the theory that the same polarities repel each other,repulsive force between the two

 irons makes the pointer deflect.When the torque and the restoring torque keep a balance,the pointer 

on the moving iron will point to a scale mark,which is the measured value.

 

9.The ellectromagnetic meters can be used for AC circuits under ordinary circumstance as well as for

 DC circuit instructed with TRMS.The structure of this kind of meters is simple,yet the accuracy is high,

as well,they can be used for *0/*0Hz circuit.Special frequency should be marked out when the order is placed.
