AT516 DC Resistance Tester is a benchtop instrument with fully automated real-time detection controlled by a high-performance ARM microprocessor..
The instrument has an accuracy of 0.05% and a measurement range of 1μΩ~20MΩ. The resistance value is displayed in 5 bits with 30000 readings and a maximum sampling speed of 7ms. The instrument has built-in temperature compensation interface to compensate for errors due to temperature..
The instrument has built-in 14-step comparator output, which can set 10 qualified files, and all the comparator results can be output through the Handler interface..
The instrument comes standard with RS-232 interface, using SCPI (Standard Command for Programmable Instrument standard command set) and Modbus protocol (Modbus has become the national standard GB/T19582-2008) applied to automatic sorting system to complete automatic pipeline test. Communicate with computer, PLC or WINCE device to efficiently perform remote control and data acquisition functions..

Smart and modern designs: these incentive charts have 6 different colors (lemon yellow, peach red, blue, sky-blue color, lavender purple, lime green), these bright colors are eye-catching, which can give you a delightful mood.
Also, the reward charts have enough space for names and tags.
Quality material: laminated incentive charts have protective covers which can protect from oil and water, the paper is printed with quality ink, which can make the chart shiny and bright for a long time, the laminated cover layers ensure no stain left.
Reusable and easy to wipe off: these chore charts are laminated with PET film which makes the incentive charts reusable.
You can apply dry erase markers on the incentive charts/ chore charts/ responsibility charts, and use tissues to wipe off the marks, so it is very convenient and easy to use.
Appropriate size: each dry erase incentive chart is 11 x 13.4 inches, the size is neither too big nor too small and is good for using for different purposes.
And the reward stickers are about 0.56 inches/ 1.4 cm, which have golden outlines.
Wide applications: these incentive reward charts can be applied to track students' behaviors, record their homework and assignment progresses or check with their chore responsibilities or school ....
