Unrestrained Storage and Connection

   -- Data storage no longer be bound by transmission wire

 

GW INSTEK rolls out the new generation Dual Measurement Multimeter -- the GDM-834x series, which has two models -GDM-8341 and GDM 8342. Its exceptional features include 50,000 counts, VFD dual-display, 0.02% basic DC voltage accuracy and a USB protocol connector to provide users with measurement precision, lucid data observation, and the convenience to connect with the personal computer.

 

The GDM-834x series not only supports the fundamental measurement items provided by general multimeters, but also equips with capacitance and temperature measurement functions. Furthermore, the GDM-834x series also provides many auxiliary functions to meet the measurement requirements for manufacturing process tests, educational experiments and testing facilities.

 

With respect to storing and retrieving data, the GDM-834x series has two methods to offer: first, the USB flash drive storage function --- operating alone without connecting with a computer; second, USB interface (virtual COM port) and optional GPIB interface (must be installed in factory) for automatic measurement system users to conveniently save and retrieve data.

 

Convenient USB flash drive storage function

 01

The major distinction between GDM-8342 and products in the same category is that GDM-8342 provides USB flash drive storage function, which allows users to conveniently save data into a USB flash drive through a simple and proper setting. This unique function, different from other digital multimeters which must first save data into its own internal memory then transfer out the file, or connect multimeters with a computer to retrieve data, not only savesoperational time but also cuts down the cost and time of developing programs.

 

The USB flash drive storage function incorporates two modes -- basic and advanced, which can be selected from the front panel. When the basic mode is on, data will be saved into an automatically established new folder (time of established file will be determined by system default) and the starting time of data logging will use a fixed time marker (00hr: 00min: 00sec). For advanced mode, users can designate a file path to save data or establish a new folderand the starting time of data logging is determined by users’ inputs (for instance: 23hr: 45min: 32sec). The number of data files can be saved in one second is determined by the speed of selected function.

 

The USB storage function allows each flash drive to establish 100 folders (GW000 ~ GW099). Each folder has a capacity of saving 5,000,000 data files (which are divided into 100 sub-file names, therefore, each sub-file name can save 50,000 data files. Take folder GW000 as an example, internal file names are GW000_00 ~ GW00_99). The storage format is CSV, which can open files and conduct file analysis by existing tools. (such as Microsoft Excel)

 

Selectable measurement speeds

02

The GDM-834x series has three selectable measurement speeds- fast/medium/slow. For instance, the DC voltage measurement can reach 40 readings per second on the fast mode, which can maximize the effectiveness of each measurement.

 

Various measurement items and functionalities

03

he GDM-834x series provides various measurement items and functionalities compared with that of the products of same category. There are twelve major measurement items of this series including AC voltage/current, DC voltage/current, AC+DC voltage/current, two-wired resistance, capacitance, Frequency/ period, diode and continuity beeper test. Temperature measurement is an optional function for GDM-8342. Many auxiliary functions, such as maximum/minimumvalues, reading hold, relative values, dB, dBm, algorithms (MX+B, 1/X, Ref%) and comparison, are designed to reinforce the major measurement items to satisfy users’ daily working requirements.

 

Dual measurement/dual display

04

The GDM-834x series, similar to GW INSTEK’s 6 1/2 and 5 1/2 digits multimeters, equips with dual display to support the possible combinations of measurement items. For example, the DC voltage and current or DC voltage with AC element will appear when monitoring components of test wiring. The results of each measurement will simultaneously appear on different displays that not only save users’ precious time but also exempt users from the trouble of selectingdisplays while reading measurement results.

 

Command compatibility & Free software-remote control and data retrieving

05

For GDM-8246 users, the GDM-834x series also provides a complete command compatibility (SYSTEM\LANG\COMP). Users can replace machines through the simple setting of the GDM-834x series without worrying the extra cost to modify the existing program and the delay of production time.

 

The GDM-834x provides free USB protocol connection software- Excel ADDins for users’ easy access. After installing the software, Microsoft Excel will establish Marco for users to directly control the setting of the GDM-834x series to record the results of the measurements. The recorded data will be synchronously transformed into graphic displays via Excel drawing function that not only eliminates the cost and time of developing programs but also overcomesthe compatibility issue of different programming languages
