Questions and answers
to test the voltage in a 12volt car battery, do I use the left hand side of the QM-1500 labled V... at 20.
To test the voltage in a 12-volt car battery using the Protech QM1500:
1. Insert the black test lead into the COM (negative) jack.
2. Insert the red test lead into the VΩ (positive) jack.
3. Set the function switch to a DC voltage range above 12V, such as 20V.
4. Connect the black lead to the battery's negative terminal.
5. Connect the red lead to the battery's positive terminal.
6. Read the voltage on the display.
Make sure the test leads and battery terminals are clean and secure during testing.
