The GDM-300/400 Series Hand Held DMM are a compact, high precision, battery operated multimeter
series designed to meet of service engineers. The GDM-300/400 Series design is driven by mobile-
oriented features: automatic power off to preserve battery life, a large backlight display for crisp viewing,
a rotary selector and push buttons to ease operation, and temperature measurement for outdoor use.
The basic functions match the depth of bench-top multimeters: fuse-protected current input, true RMS
for accurate AC measurements, Auto ranging, Duty cycle, and Relative mode. These compact, reliable,
and economical devices are ideal for any engineer.
