Upgraded sound and light alarm sound + light dual alarm When measuring continuity, there be an alarm sound and an alarm light 2000V voltage, 20A current Mine photovoltaic electrician maintenance 2000V measurement jack, larger measurement range, more professional NCV non-contact voltage detection and insulation measurement are Place the NCV position on the top of the meter close to the AC power source and the meter sense the AC voltage and sound an alarm Backlight night vision function High-quality rubber sheath Turn on the backlight and it is suitable for various working environments. The rubber protective cover is not afraid of falling and effectively protects the instrument AC voltage:100mV~2000V DC voltage:100mV~2000V AC current:10μA~20A DC current:10μA~20A resistance:10~60MΩ capacitance:50nf~100,000µf (The product printed words depending on the batch, but this does not affect use) Color: As Shown Material: ABS Package Contents: 1 * Digital Multimeter 6000 Counts Only the above package content, other products are not included.
