Control

The Multitronics RC-700 trip computer is controlled using the keys that are located on its front console.

• The PARAM button allows to enter the mode of indication of the engine performance indicators - fuel consumption, cooling liquid temperature.
• TRIP switches the display to the mode of indication of the average values of the parameters for a specified period of time-diurnal, stay in traffic jams, during a trip and in the mode of a taximeter.
• SERVICE displays the date of maintenance, decoding of error codes, temperature drop, drying of candles, etc.
• SETUP brings up the settings, protocol, voice warnings, screen, etc.
• SET allows you to change the type of display parameters - digital, graphic or arrow, change and confirm the selection.
• + - with a short press (less than 2 s), increases or decreases the edited parameter, the brightness of the display, and for a long time - the volume.
• ESC cancels the action or allows you to go to the previous menu.
• F calls up the user menu.
• ˅ allow you to navigate through menus or sort through various combinations of parameters.

Modes of operation

In the diagnostic mode, the computer's auto-detection or manual setting of its type is used. In this case, you can decode and reset the error codes.

Universal mode uses the data of the speedometer and injectors of the gasoline engine. For diesel engines, the mode is not applicable.

How to configure the protocol

1. Turn on the Multitronics RC-700 on-board computer. When the engine is not running, the BC will go into the economical mode and turn off the backlight.
2. When the ignition is switched on, autodetection of the protocol will begin.
3. If you did not install the protocol, you must specify it manually. To do this, turn off the ignition, wait until the display turns off, press SETUP in the settings screen, and go to the menu item "Sources - Op. duct. Aut. - Hand. - Flow. ", Select the desired protocol. Each time, you should confirm your choice with the SET key. Individual protocols may require additional parameters.
4. The correctness of the choice should be checked. To do this, start the car, press PARAM, open the screen with 1 parameter and make sure the motor temperature and its speed are correct. If the values are incorrect, you need to repeat steps 3 and 4, change the type and subtype of the protocol, errors, etc., and only then install another protocol. In addition, you need to investigate whether the change in speed affects "Instant fuel consumption." They will not be valid until calibration.
5. Incorrect display of parameters for all protocols means that this car is not supported and operation is possible only in universal mode.

Accounting for the distance traveled and speed

Different cars use different tires and odometers. Therefore, to ensure the correct values of speed and distance traveled, the instrument must be calibrated. This can be done in two ways:

1. Make the calculation yourself and enter a speed correction.
2. Enter the reference value of the distance traveled into the Multitronics RC-700 on-board computer. The necessary calculations will be performed by the program.

For calibration, you must reset the GPS receiver's path and route, the average values of the parameters in "Medium display. Parameters Reset1 "by pressing TRIP and F to display" Hot Menu - Medium ". Select Reset Reset1, SET and ESC.

Go more than 10 km according to the testimony of the trip computer and stop.

Press SETUP, select "Correction - Eth. Mileage "and enter the actual data by the odometer or GPS receiver.

Corrections will be calculated automatically and recorded in the device memory. The mileage value in the "Average display. Parameters Reset1 "will change to the actual value. The instant and average flow rate for 100 km, the distance traveled and the mean speed will also be automatically corrected.

Regulation of fuel consumption

You can do this yourself or by entering a reference value. The procedure is as follows.

Pour the full tank. Reset the parameters "Medium display. Parameters - Reset1 ". Press TRIP and F, call "Hot Menu Middle" and select "Reset Reset1". Spend more than 25 liters of fuel without refueling as indicated by the on-board computer. Fill up to the full tank. Through SETUP go to "Amendment - Et. Flow "and enter the volume of the filled gasoline according to the indications of the column.

After that, the correction will be calculated and installed automatically. For dual-fuel cars, the order is different.

Remaining fuel

This feature Multitronics RC-700 user reviews are called among the most useful. The on-board computer indicates the amount of fuel remaining in three ways, as defined in the "Set-up display -Source. - Tank type ":

• Estimated, without connection to the sensor level of filling the tank. The data changes after each refueling, and the BC calculates the remainder. This mode is very accurate and does not depend on the sensor, voltage and position of the car. This requires setting the fuel consumption.
• DUT - using sensor data.
• DUT ECU - without connection, the data can be read from the diagnostic line.

In the last two modes, the need to enter data manually disappears, since there are indications of the sensor. If the computer data is unsatisfactory, it is recommended to set the "Calculated" mode.

Error Codes

You can read and reset error codes only when connecting to the diagnostics line.

To view the errors, start the motor, press PARAM and wait for communication with the ECU. Press SERVICE and go to "Maintenance - Errors - ECM - Computer errors". Another way is to press F and select "Computer errors". You can view errors using the navigation keys.

In order to reset errors, you need to turn on the ignition and go to the "Display TO - Error Reset". If the action fails, repeat.

The computer only reads and resets the error codes that the computer gives out, it does not record them. Errors in the computer can only be reset by command. The limited amount of memory Multitronics RC-700 allows you to decipher only the basic error codes, extended codes can be deciphered using technical documentation on the car.

Hybrid cars

It is correct to calculate the consumption of a vehicle equipped with gas-cylinder equipment, if the computer is connected correctly, the "Gas / Gas" mode is activated and the average parameters are reset. The remainder in the gas cylinder is measured solely by the calculation method.

By connecting and activating the function, you must calibrate the fuel consumption. Gas-cylinder equipment transfers from one type of fuel to another automatically and is sometimes limited to one type. During start-up and warm-up of the engine, for example, only gasoline can be used, and the transition to gas is possible only after raising the temperature. Therefore, automatic flow calibration is difficult. Manual calculation is applied.

For calibration, it is necessary to fill the vehicle with all kinds of fuel as much as possible. Set "Settings display - Avg. Param. - Autoset Gas / Gasoline - Ruchoy. To reset the data, select "Reset G / B".

Spend the fuel completely and refill the tank and cylinder, recording the volume.

Calculate the correction factor:

Correction = ((E * (100 + x%)) / M) - 100, where

• E - actual fuel consumption;
• M - the value of the flow on the route computer in the "Display cf. Parameters - Benz. "And" Gas ";
• X% is the correction set before the measurement.

Hot Menu

Provides quick access to the functions of the "Setup display" screen. Activated by button F from the "Display Parameters". You can configure the hot menu in the "Settings display" by selecting the desired item and pressing F and SET. The number on the left indicates the number in order in the hot list.

You can clear the menu in the "Setup display - Cleaning the mountains. Lists - Options ».

Countdown

This function allows you to view the history of parameter values. Available in graphical mode with the motor off.

For installation in the "Setup display - Displays - Graphic" select "Countdown", press SET, "Yes", ESC three times. Navigation buttons allow you to navigate the graph. You can see other charts at a specific time by selecting "Countdown - No" and pressing ESC three times.

The function can be called from the hot menu. To do this, press F, select "Reverse". Count Yes, return to the graphical screen. Move using the +/- buttons. Other graphs can be viewed by pressing F and selecting "Reverse". Countdown - No ". After returning to the graphic screen with the navigation buttons, open another display.

When the car starts, the function will automatically turn off.

Parking area

Enabling the parking radar Multitronics switches the trip computer to the parking screen.

There are 2 representations - graphic and digital. The display shows information about the distance and the minimum distance from the front and rear radars to the obstacle closest to the obstacle of the sensor, the speed and sensitivity of the radars. Thus, as you approach, the background color changes from green to red and "STOP" appears.

The user menu "Parking" and "Parking ahead" can be accessed by pressing the F button.

Medium Screen

Switch to the screen of average parameters by pressing the TRIP button. It consists of 9 screens:

• "Trip" - calculates the parameters for 1 trip. The data is reset when the ignition is switched on, taking into account the setting of the interruption time. You can manually reset the data.
• "Reset1" - calculates parameters between zeroing data. Autoreset can be set in the range 1-99 days. Usually choose 7, 30 and 90-day period.
• "Reset2" is the calculation between refueling, since the discharge is made with the increase in the volume of fuel.
• "Cumulative" - zeroing is done manually. Designed to maintain general statistics.
• "Traffic" - takes into account the data for speeds less than the "Cork speed" setting.
• "Not in traffic jams" - calculation of parameters for speeds above the preset.
• "Gasoline" and "Gas" - accounting for different types of fuel.
• "Taximeter" uses for 5 day and night tariffs, a premium for speed, the minimum cost of the trip and filing.

These screens display information about the time, mileage, fuel consumption, speed and cost of the trip.

The maintenance screen

Go to the maintenance screen by pressing the SERVICE button. The display shows the parameter, when it is zeroed, a warning is displayed that it is necessary to pass the maintenance. To set a new value, enter the mileage before the next maintenance and date.

The screen menu depends on the diagnostic protocol and firmware.

Settings screen

You can go to the settings display by pressing the SETUP key. The menu consists of several subsections, depending on the function. The list is selected with the navigation buttons with confirmation by pressing the SET key. Pressing SET on the parameter switches its values. If there are more than 2 values, then press +/- button to confirm with the SET button. Pressing F adds a row to the list of the user menu.

Reviews

Multitronics RC-700 user reviews are rated positively. Buyers appreciated ease of installation, the presence of a speech synthesizer, pronouncing faults and decoding their codes, quick access thanks to the hot menu. Especially useful consider the possibility of connecting parking sensors, accounting for gasoline consumption, fuel quality assessment.

Discontent is caused by the limited life of the control buttons - after 2 years of one press it becomes insufficient, and also the stabilizer HT7533-2 operation in the power circuit. Element works at the limit of its capabilities, and the high temperature in summer and heating in winter contribute to its overheating. As a result, the on-board computer malfunctions, overestimated data on air temperature and mains voltage (for example, 16.0 V instead of 14.3 V).
