Display: 0.32-inch LED digital tube, voltage with 4-bit red LED display, current with 4-bit green LED display, timing, frequency with 5-bit red LED display
Widely used in gas pipeline leak detection, household gas prevention, gold mining, tunnel mine operations, oil and gas extraction, hazardous goods storage warehouses, etc.
It is convenient for users to safely detect various combustible gases, such as: methane, carbon monoxide, gasoline, ethylene oxide, etc.
Scope of application: can test 74ch series, osmo series, cd4000 series, hef400 series, 4500 series, operational amplifiers, interface chips, optocouplers, automatic transistor identification, voltage regulator voltage identification
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
Different test modes: 5v mode, 3.3v mode, auto mode
