Weight: TA804A is about 167 grams, TA804B is about 175 gramsFeatures:1. Quick recognition, intelligent measurement, large screen display2. Adapt to multiple occasions: electrician installation of home improvement lines, maintenance of electronic products, maintenance of electric car circuits, etc.3. NCV voltage sensing: There is a NCV test point at the front of the meter, which is close to the AC voltage. According to the different strength of the signal, the buzzer will emit an uninterrupted sound, and the analog bar will also be based on the strength of the signal. Show different number of segments4. Zero live wire measurement: insert the red test pen tip into the neutral or live wire. If it is live wire, the buzzer will sound continuously, and the panel indicator will flash at the same time, and the analog bar on the screen will display full grid. Intermittent prompt sound, the screen simulation bar shows half or one grid5. With flashlight lighting, it is convenient for users to measure in the dark environment6.
