FIGURE 59. RESISTANCE.
Setting the TEST SELECT switches to the required test number tells the VTM to make a resistance
measurement when the TEST button is pressed and released.
The VTM supplies constant electrical current to the vehicle/equipment under test.
Voltage across equipment under test is measured, and resistance is calculated by the VTM.
The VTM displays the resistance in ohms or kilohms.
