1        Basic features

 
u
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 interface, 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, maths 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), 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-wire and four-wire measurement for resistance, 10Ω and 1GΩ measurement range for extension.
Measurement of period and frequency, and frequency can reach to 300 kHz.
Capacitance measurement.
For temperature measurement, users can set sensor measurement by themselves.
Maximum current measurement capacity reaches up to 12A.
Many math functions: statistics (maximum value, minimum value and average value), zero elimination, dB, dBm and limit.
Graphic display: tendency chart, histogram, history curve, listing and other display methods.
Support SCPI programming language and many command sets (Agilent 34401A and Fluke 45).
With internal and external calibration functions.
