• For quick checks of AC voltage presence, the NCV function is very convenient and safer than using test leads.
• When measuring current, always ensure the multimeter is connected in series with the load and the correct input jack (mA or 10A) is used to avoid damaging the device or blowing a fuse.
• The kickstand on the back of the multimeter allows for hands-free operation, improving safety and convenience during measurements.
• Remember to turn the multimeter OFF when not in use to conserve battery life.
