Digital Clamp Meter -- ACA, ACV, DCV, Ohm, Diode, Buzzer.
The GCM-403 is digital clamp meter can measure AC/DC voltage, AC/DC current, resistance, diodes, continuity, capacitance, frequency and temperature. Tapered jaws, auto range, data hold, REL function and auto power off which makes it a superb tool for electricians.
The GCM-407 is digital clamp meter with true RMS measurement. Featuring tapered jaws, a wide range (AC 600A/750V, DC 1000V max input), capacitance measurement as well as non-contact voltage sensing function and the ability to keep MAX/MIN or hold data and automatically power down make the GCM-407 suitable for almost any cable measurement task.
Compared with the old model- Advantages
GCM-403 expanded measurement items:
Compared with the old model- Disadvantages
Smaller GCM-403 Clamp which is only ∮ 28mm
GCM-403 does not have Max Hold
Compared with the old model- AdvantagesGCM-407expanded measurement items: Voltage Range/Capacitance and expanded functionalities : No Contact Voltage (AC only)/ Min Hold/REL/Backlight
