LCD Digital DT-830B Electric Ohm AC/DC 750/1000V Amp Volt Ohm Mete r

Descrtion:

The DT830 digital is a three-and-a-half-digit LCD display small digital . 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 is ±1999, which can automatically display "0" and polarity, and display "1" or "-1" when overloaded, and the diode gear for short-circuit check.

Specifications:

1. Measuring range

⑴ AC and DC voltage (AC frequency is 45Hz～500Hz); DC ranges are 200mV, 2000mV, 20V, 200V and 1000V respectively; AC ranges are 200V and 750V respectively; DC accuracy is ±(0.8% of reading + 2 words )

⑵ DC current

The measuring ranges are 200μA, 2000μA, 20mA, 200mA and 10A. The DC accuracy is ± (1.2% of reading + 2 digits), and the maximum voltage load is 250mV.

⑶ Resistance:

The ranges are respectively: 200Ω, 2000Ω, 20kΩ, 200kΩ, and 2000kΩ. The accuracy is ± (2.0% of reading + 3 words).

The test conditions are: VCE=2.8V, IB=10μA.

⑹ Short circuit detection:

Test circuit resistance＜20Ω±10Ω

2. Sampling time: T S = 0.4S.

Panel and Operating Instructions:

1. monitor

Three and a half digital LCD display

2. switch

Pre it to turn on the power, and turn it off when not in use.

3. Capacitance measuring socket

This watch has no capacitance test function.

4. Function range switch

Choose different measurement functions and ranges.

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

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

6. Current jack

When measuring AC and DC currents le 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.
