Digit multimeter, as one of the essential products in electronic testing field, is widely used in modern times and gains much popularity among engineers due to its advantages of high precision, high speed, high resistance, digit display, accuracy of reading, high anti-interference capability, high automation of measurement, etc. The application requirements for digit multimeter are also developed and changed a lot. Multimeter in ET32 series is equipped with 3.5 inches color display with high resolution and embedded intelligent operation system, providing more information and functions, simpler operation, wider testing range and more flexible and convenient system building. It is a new digit multimeter leading the developing tendency above.
The double-benchmark calibration function peculiar to the product enables users to realize calibration of all the functions with only one 10V standard voltage and one 10kΩ standard resistance, with the calibration time for the whole machine not exceeding 1 hour.

Basic Characteristics
● 6 1/2 resolution (ET3260/ET3260A).
Or 5 1/2 resolution (ET3250/ET3250A)
● The digital multimeter is equipped with a 3.5-inch color display screen (resolution ratio is 320*480), which is powerful enough to provide greater coverage of content, flexible display of a variety of graphical interfaces, and good display effects. The users can also customize the display interface depending on their needs, and choose from various display functions such as graphics, figures, math and other functions simultaneously on the screen.
● Bi-parameter display can display two parameters in one input signal (such as display AC voltage value and AC frequency value during AC voltage measurement).
● Conduct remote operation through interfaces of IEEE 488 (ET3260/ET3250), RS-232, LAN and USB Device.
● With functions of trigger input and output of measuring completion.
● The front-panel menu is with USB port for data storage, procedure updating and configuration.
● Customers can update host software by themselves.
● Two-line and four-line measurement for resistance, 10Ω and 1GΩ measurement range for extension
● Measurement of period and frequency, and frequency can reach to 300KHz.
● Capacitance measurement.
● For temperature measurement, users can set sensor measurement by themselves.
● Maximum current measurement capacity reaches to 12A.
● Many math functions, such as statistics (maximum value, minimum value and average value), zero elimination, dB, dBm and limit.
● Graphic display, such as run chart, histogram, history curve, listing and other display methods.
● Support SCPI programming language and many command sets (Agilent 34401A and Fluke 45).
The front and rear panel menus of the instrument are all equipped with input terminal (ET3260/ET3250).
● With internal and external calibration functions.
