Voltmeter - BGS technic 40107 Manual De Instrucciones

Таchometer
Тhe tachometer is used to measure the engine speed. The engine speed must be known in order to:
- adjust the idling speed
- check the ignition
- adjust the timing
- check the adjustment
1. Press the tact switch to light the RPM indicator.
2. Connect the inductive pick-up to the first cylinder.
3. Connect the red clip to the positive battery terminal (+) and the black clip to the negative battery
terminal (-). (See figure 1).
4. Start the engine and read the RPM from the display. Compare the RPM reading with the figure
recommended by the vehicle manufacturer. Should any deviations be found, mark appropriate
adjustments.

Voltmeter

The voltmeter can be used to check the battery voltage and the supply voltage to various electronic
devices, e.g. lamps, etc.
1. Testing of battery voltage under starting current load.
a. Disconnect the ignition by pulling the plug off terminal 1 (1,D,RUP,-) on the ignition coil.
b. Press the tact switch to light the VOLT indicator.
c. Connect the black clip to the negative battery terminal (-) and the red, green clips to the
positive battery terminal (+).
d. Start the engine by another person.
e. Read the voltage from the display.
NOTE: If the battery voltage is less than 9V, strongly recommend to ask a professional technican to
check the car battery again.
2. Testing of a car battery on loading (e.g. lamps).
a. Connect the black clip to the negative battery terminal (-) and the red clip to the positive
battery terminal (+).
b. Connect the green clip to the positive terminal of the loading device.
c. Switch on the device and read the voltage from the LED display.
NOTE: If the voltage is too low, this hints there is leakage through the respective leads or
connections. This is frequently happened by heating of connecting terminals, switches or parts of the
leads.
NOTE: When the voltage drops greater than what specified in your owner's manual, strongly
recommend to ask a professional technican to check this again.
