AC/DC current and voltage tester

Dimensions: 12.60 * 7.00 * 2.40 cm / 4.7 * 2.8 * 0.94 inch

Operating temperature: 0 - 50 ℃ 

This digital multimeter is a three and 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

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

Measuring range

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

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

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

Diode conduction voltage: the range is 0～1.5V, and the test current is 1mA±0.5mA

Triode β value detection: the test conditions are: VCE=2.8V, IB=10μA

Short circuit detection:  test circuit resistance＜20Ω±10Ω

Sampling time: T S = 0.4S

Three and a half digital LCD display

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

Capacitance measuring socket

This watch has no capacitance test function

Function range switch: choose different measurement functions and ranges

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

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

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

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

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.
