Reference for transistors, MOSFET protection diodes, and amplification factors that can detect the forward bias voltage of the transistor's emitter.
Measure the gate threshold voltage and gate capacitance of the MOSFET
Fast test speed, effective component test: 2 seconds (except for large capacitors, it takes a long time to measure large capacitance, and the measurement time is one minute is normal)
The D52-2058 rail-type digital display multi-function meter simultaneously displays the measured AC voltage, AC current, power factor, active power, frequency, and electrical energy (electricity) on the meter.
Please check AC80-300V for measuring 110V 220V voltage, and 200-450V for measuring 380V voltage
Measurement accuracy: 1% +/- 2 words
Display: 4-digit red 0.31-inch LED digital tube for voltage display, 5-digit red 0.31-inch LED digital tube for current and frequency display, 5-digit green 0.31-inch LED display for active power and electrical energy (electricity) Digital Tube
Measurement range: AC voltage: AC80. 0-300. 0V, AC200. 0-450. 0V, AC current: AC0-100. 0A, the current display resolution is 0. 01A when the measurement current is less than 100A, and the measurement current is greater than 0.01A At 100A, the current display resolution is 0.1A, and the range is automatically converted.
Active power: (measurement voltage AC80. 0-300. 0V) 0.0-30000W (AC200. 0-450. 0V: 45000W)
Electric energy: 0. 000-99999kwh, decimal point automatic conversion
It is widely used in gas pipeline leak detection, household gas prevention, gold mine field, tunnel mine operation oil and gas exploitation field, dangerous goods storage warehouse, etc.

Integrate more than 1,300 types of chip data models and more than 420 types of transistor data models, covering most common general-purpose devices within 24 pins, which can greatly reduce maintenance workload and improve work efficiency
Press the Enter key to turn on the machine for the first time and automatically run a self-test. The self-test detects the battery voltage and displays it on the screen after more than two seconds. When the battery voltage is lower than 7v, replace the battery to ensure the measurement accuracy. If If there is no alarm, the measurement work can be started
Nativead 10 ad, the theoretical resolution of 5v voltage is 0.0048v
Due to the use of batteries for power supply, it is not suitable for measuring high-power thyristors
The Zener value must be based on the actual measurement, not just the nominal value
The default directory for initialization is the search directory
