Features:
Highly sensitive & accurate multimeter in a large screen dispaly, easy operation.
Basic function: DCV/DCA/ACV/Ω/dB/etc.
High input impedence: DC 20KΩ/V, AC 9KΩ/V.
20ranges in 8 functions.
Overload protection.
DB measurement:
DB is the sound level voltage, and the input signal is connected to COM and OUTPUT socket respectively.
The range is in AC voltage, in unknown cases it is from high to low.
If it is AC 50V the pointer is at 30V, dB will add 14dB at 18 dB which is the dB reading at this time.
Differenct added decibels for different voltage can be found in the instruction manual.
User should be sure of understanding the full content of the user manual before using.
Always remember: make sure the range is in the right position in the first place, then check the test leads.
Read the SAFETY CAUTION, Maintainance and repair in the user manual.
