Gauging stands E-250M-02 are designed to check removed from the car and the new electrical equipment. The check can be carried out on transport companies, auto-repair factories, auto service stations, as well as specialized training and educational institutions, and auto parts stores.
The principle of operation of the stand E-250M-02 is to simulate operating conditions and measuring the characteristics of electrical equipment to test its performance and condition, troubleshooting.
With The measurement and adjustment stand E-250M-02 is diagnosed:
- Generators at idle and under load;
- Starters at idle speed and stagnation;
- Traction relay-starters;
- Switching relays;
- Electric vehicle parts;
- Armature winding;
- Semiconductor devices;
Stand E-250M-02 is an updated version of the stand E-250-02, and is different from the previous model, the presence of microprocessor control, digital signal processing and wireless communication with the computer.

The measurement and adjustment stand E-250M-02 differs from previous models by the following features:
- Connection to a PC via a protocol Bluetooth;
- Continuously variable parameters generator load throughout the range;
- Dynamically adjusting the motor speed;
- Determining the speed of the generator and starter shafts by remote tachometer;
- Increasing the parameters variable voltage source to 26 V and currents up to 12 A;
- Availability of the software in Russian to display the different signals on the PC;
- LED backlight table and instrument panel;
- Mode control buttons, equipped with LEDs to illuminate the selected modes;
- Protection of electrical circuits of the generator and starter from the limit overloads and short circuits;
- The possibility of automatic measurements of starters and generators in cases where the PC;
- Special niches in the body to move the stand E-250M-02 loader and hydraulic carts.
Ergonomically designed control panel provides quick development of skills to work on a stand-250M E-02 and the mastery of these tests. The controls are grouped logically complete and functionally clear blocks. Bright easy to read indicators.
Full brake for starters
Used to test the starter mode and full braking torque measurement (starter gear meshes with the sector gear brakes).
Reinstall the spring sensor provides a check on the stand E-250M-02 starters on both the left and right rotation.
To determine the presence and continuity of short-circuited turns in the coil, and that the direction of the winding number of turns in the winding sections. The principle is based on a comparison test emf induced in the winding sections by the magnetic flux produced by the magnetizing inductor. Induced in the winding sections EMF removed from the collector plates by means of contact with the armature device.
Determination of the speed at idle and under load produced by the stroboscope (the "no rotation").
Adjustable drive a generator
The drive consists of an induction motor with a 2-pulley and the creeks of the inverter, which allows to produce a smooth measurement speed and load current. Control knob is mounted on the front panel. The "left-right" change the direction of rotation.
Examples of the use of stand-250M E-02:
Checking the starter
The measurement and adjustment stand E-250M-02 allows you to check the starters as passenger cars and light trucks. For installations that use two universal mounting adapter. Made of solid steel, they have a number of holes. The adapter is installed on the starter as follows: holes are aligned with the standard, and in the eyes fixed on the bolts. A starter adapter installed on the stand E-250M-02 by four fasteners. Next, connect the positive lead and the masses to the corresponding terminals on the bench. Using the force sensor readings are taken in the full braking:
- The sensor is mounted in the original position;
- The torque developed by the starter, is transmitted through the locking tooth on the force sensor;
- Receives a signal from the sensor to a measuring circuit of the stand and displayed on devices which record time the amperage and voltage.
Stands E-250M-02 supports inspection starters, both the left and right rotation. Easy to test idle. Can be used as a manual mode the starter as automatic, which shuts off after 4 seconds. All the indications are also removed from the measuring devices.
Checking the generator
First of all, the generator is attached to the stand: to use the generic chain fasteners. Then the power is connected. Bench check e-250M-02 completely mimics the conditions of a real car. The excitation of the generator windings, and sets the voltage generator This disables. Then turn drive a generator. It is reversible - the rotation is in any direction. Next, you need to file a strain that is easy to control on the meter. Maximum current - 150 A. One of the advantages of E-250M-02 is a sensor rpm alternator pulley. This allows you to take performance speed as the generator and the motor. Digital readouts are displayed on the device. The efficiency at different speeds can be easily controlled by a voltmeter. If the schema generator warning light is provided, it can be easily connected to a stand-250M E-02.
