Description:

The DT830 digital multimeter is a three-and-a-half-digit LCD display small digital multimeter. It can measure AC, DC voltage and DC current, resistance, transistor β value, diode conduction voltage and circuit short circuit, etc. A rotary band switch can change the measurement function and range, with a total of 19 levels.

The maximum display value of this multimeter is ±1999, which can automatically display "0" and polarity, and display "1" or "-1" when overloaded, and the diode gear for short-circuit check.

5. 10A current jack (cannot measure current greater than 10A)

When measuring AC and DC currents greater than 200mA and less than 10A, the red test lead should be inserted into this 10A current jack.

6. Current jack

When measuring AC and DC currents less than 200mA, the red test lead should be inserted into this current jack.

7. V/Ω jack

When measuring AC and DC voltage, resistance, diode conduction voltage and short-circuit detection, the red test lead should be inserted into this V/Ω jack.

8. The black test lead from the "COM" jack of the grounding common terminal is always inserted into this grounding jack.

9. Beta test socket

Insert the collector, base, and emitter of the transistor under test into the "C", "B", and "E" jacks respectively, and pay attention to distinguish whether the transistor is an NPN type or a PNP type.
