A simple demo video: https://youtu.be/vVtmyE5ElQU Features: <>Use LTZ1000ACH as voltage reference. <>Use VHD200 for 7V to 10V conversion. <>7.5Digit DC Voltage resolution, INLmin<1ppm, TCmin<0.3ppm. <>6.5Digit DC Current resolution, INLmin<2ppm, TCmin<3ppm. <>9 physical resistors Ohm Output with 4-wire. <>Low noise 1.5uVp-p@10Hz typical. <>Additional DC voltage measurement function. <>Fully digital calibration. <>Small size (140x100x83mm), battery powered, suitable for portable use. Introduction: JOY7307 is a new works of selena2211 ( Chinese nickname: 乐逍遥) (NOT me). JOY7307 is a multifunction calibrator powered by a lithium battery, suitable for portable use. JOY7307 uses LTZ1000ACH as the voltage reference and VHD200 as the 7V to 10V conversion resistor to achieve ultra-low temperature drift, high stability and low noise. The DC Voltage resolution is 7.5 digit, the lowest adjustable value is 0.1ppm. Functions: <>DCV OUTPUT: #10V Range: -10uV~11V adjustable, 7.5Digit, INLmin<1ppm, TCmin<0.3ppm #1V Range: 0uV~1.1V adjustable, 7.5Digit, INLmin<1ppm, TCmin<1ppm <>DCI OUTPUT: #100mA Range: 0~110mA adjustable, 6.5Digit, INLmin<2ppm, TCmin<5ppm #1mA Range: 0~1.1mA adjustable, 6.5Digit, INLmin<2ppm, TCmin<3ppm <>Ω OUTPUT: #ΩRange using 9 physical resistor, they are 0Ω, 10Ω, 100Ω, 1kΩ, 10kΩ, 100kΩ, 1MΩ, 10MΩ and 100MΩ. The performance of Ω range is related to the actual resistor used, and the calibration value is 7.5 digits. <>MEAS: #DC Volt meter, 12.5V range, 7.5Digit, INLmin<1ppm, filter is enabled by default <>OTHERS: #Clock & internal temperature #LCD contrast adjustment #LCD backlight ON/OFF #Keypad tone ON/OFF Here are some images, more images and videos will upload later. |
