4. V- -
input terminal — Input terminal for voltage and resistance measurements and diode testing.
5. µA/mA input terminal — Input terminal for measuring currents up to 320mA.
6. A input terminal — Input terminal for measuring currents up to 20A.
7. Manual range button — This button is used for setting and changing ranges manually. Pressing the button once
