Introducing the GW Instek GDM-904x Series: Dual Measurement Multimeters with Automatic Identification

GW Instek rolls out the new Dual Measurement Multimeter, the GDM-904x series, which has two models: GDM-9041 and GDM-9042, to replace the existing GDM-834x series. Its exceptional features include 50,000 counts, LCD display, 0.02% basic DC voltage accuracy, Automatic Identification (A.I.) measurement and a USB protocol connector to provide users with measurement precision, lucid data observation, smooth measurement experience and the convenience to connect with the personal computer.

AUTO is no Longer Just for Switching Ranges

The GDM-904x series not only supports the fundamental measurement items provided by general multimeters, but also equips with capacitance and temperature measurement functions. At the same time, the GDM-904x series' Automatic Identification (A.I.) measurement can automatically identify measurement signals and switch measurement items before performing measurements, without the need for users to switch manually.

Furthermore, the GDM-904x series also provides many math functions to meet the measurement requirements for manufacturing process tests, educational experiments and testing facilities.

With respect to storing and retrieving data, the GDM-904x series has two methods to offer:

• USB flash drive storage function, operating alone without connecting with a computer.
• USB interface (support USBCDC and USBTMC) and optional GPIB interface (must be installed in factory) for automatic measurement system users to conveniently save and retrieve data.

Automatic Identification (A.I.) Measurement

The GDM-904x series is equipped with the first Automatic Identification (A.I.) measurement function implemented in a desktop meter. Once activated, this function can automatically identify the measurement signal, including AC/DC voltage, diode, resistance and continuity test, without the need for users to manually switch the required measurement function.

The GDM-904x series will automatically switch the measurement items and perform the measurements, allowing users to perform measurements more smoothly and save operation time.
