What are the main differences between a desktop digital multimeter and a conventional handheld multimeter?
The display digits are different, the measurement accuracy is different, and the extended functions (232 interface, etc.) are different.
What are the most important indicators of a desktop digital multimeter?
Display digits and measurement accuracy.
What are 1/2 digits, 3/4 digits, 4/5 digits and 50000 readings?
The first place on the left shows the title 1/2 that is less than 2, and the title less than 6 is 3/4, 4/5, and 50000 is the maximum reading of 50000.
What are the measurement functions of the desktop digital multimeter?
Basic functions: In addition to measuring AC and DC voltage, AC and DC current, DC resistance and other five basic functions
Auxiliary functions: There are also digital calculation, self-check, reading hold, error reading, diode detection, etc.
What similar products can our desktop digital multimeter be compared with or replaced?
It can be compared with Agilent34401A and FLUKE digital multimeter.
How to solve the problem of no display when TH1951/61 is turned on?
Check whether the CPU is in poor contact or the display is not good.
