Hi, my dear friend, GVDA develop two models Pen type smart multimter GD107 and GD109
do you what is the difference between this two models, let me see what is the main difference:
GD107
1, Auto power off
2, Data hold
3, Flashlight
4, Low battery indication
5, Gear selection
6, DC AC Voltage measurement
7, Frequency measurement
8, Capacitance measurement
9, Continuity measurement
10,Diode measurement
11,Live wire detecting
12,Phase sequence detection
GD109
1, Auto power off
2, Data hold
3, Flashlight
4, Low battery indication
5, Gear selection
6, DC AC Voltage measurement
7, Frequency measurement
8, Capacitance measurement
9, Continuity measurement
10,Diode measurement
11,Live wire detecting
12,Non-contact Phase sequence detection
13,NCV measurement
from above information, we know, GD107 is Contact Phase sequence detection, but GD109 is Non-Contact, also GD109 haave NCV Measurement, but GD109 not have it, but GD107 is also so pupular, why? tell me your idea about this two model? which one you prefer?
GD107
GD109
