• Capacitance, frequency measurement
• hFE test / EF function
• Data hold and relative mode
• Auto power off

The Instek GDM-398 is a 3.75 (4,000 Counts) hand-held digital multimeter. It can measure AC/DC Voltage and Current, Resistance, Diode, Continuity Buzzer, Capacitance, Frequency and Temperature (˚C or ˚F), hFE and EF function. In addition to the conventional measuring functions there is an RS232C interface, data hold, relative mode, low battery display, display backlight and sleep mode.

The GDM-300/400 Series Hand Held DMM are a compact, high precision, battery operated multimeter series designed to meet most of the daily needs for design engineers as well as service engineers. The GDM-300/400 series design is driven by mobile-oriented features, such as automatic power down to preserve battery life, a large backlight display for crisp viewing, a rotary selector switch and clear-cut push buttons to ease operation.

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.
