Tachometer (RPM) Measurement:

• Aylanadigan jantni ga aylantiring RPMx10 sozlash.
• Select the appropriate cylinder setting (4CYL, 6CYL, 8CYL) for the engine being tested.
• Connect the red test lead to the negative terminal of the ignition coil or the tachometer test point, and the black lead to a good ground.
• Start the engine and read the RPM value on the display. Multiply the reading by 10 for the actual RPM.

Dwell Measurement:

• Aylanadigan jantni ga aylantiring DWELL sozlash.
• Select the appropriate cylinder setting (4CYL, 6CYL, 8CYL) for the engine being tested.
• Connect the red test lead to the negative terminal of the ignition coil or the dwell test point, and the black lead to a good ground.
• Start the engine and read the dwell angle on the display.

jildtage Testing (Starting, Charging, Fuel Delivery Systems):

• Select the appropriate DC Voltage (V–) range.
• Connect the red test lead to the positive point of the circuit (e.g., battery positive terminal, alternator output) and the black test lead to a good ground.
• jildini o'qingtage displeyda.

Diode Function:

• Turn the rotary dial to the diode symbol (→|–).
• Qizil sinov simini anodga va qora sinov simini diodning katodiga ulang.
• Oldinga jildtage drop will be displayed for a good diode. Reverse the leads; an open circuit (OL) should be displayed.

6. Xizmat ko'rsatish

6.1 Sigortani almashtirish

The multimeter is protected by a fuse. If the current measurement function stops working, the fuse may need replacement.

• The multimeter uses a F0.5AL250V 5X20mm fuse.
