automatic annunciators for polarity, decimal point, low voltage, AC,
è
, "RANGE", "HOLD" and unit symbols.
2. Rotary function and range switch — This switch is used to select functions and measuring ranges.
3. COM input terminal — Input for the common potential.
4. V-
è è
- 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
causes the annunciator "RANGE" to appear on the display. Pressing it repeatedly then sets the meter to the
desired range. To revert to autoranging, hold the button pressed for two seconds.
