Which of the following is not a standard input jack on a digital multimeter?

• A. COM
• B. V/Ω
• C. A
• D. KV

Answer: (D)

Kilovolts are not a separate input jack on a digital multimeter. The input stage uses a common terminal (COM) as the reference for all measurements, a voltage/resistance terminal (V/Ω) for measuring voltage and resistance, and a high-current terminal (A) for current measurements (with some meters offering a separate mA jack for smaller currents). When you measure voltage or resistance, you connect the leads to COM and V/Ω. For current, you connect to COM and A. There isn’t a dedicated kilovolt (KV) jack because voltage ranges are handled through internal attenuation and protection within the same input path, not by a separate connector. So KV isn’t a standard input connector on a typical digital multimeter.
