Curve recording
|
Equipped with battery protectionSRAM,Can save the set values, sampling values, and sampling time of the device, and can be observed by sliding in real-time with finger touch on the screen;The default maximum storage time is60sky(The sampling period is1.5min),The formula for calculating sampling time is as follows:If the sampling period is set tot/min,storage timed=((65536xt)/60)/24(sky).

*Screen interface curve output--Directly save the curved interface on the touch screen or any interface requested by the customer as*.bmpSave image toUPrint the curved interface on the touch screen or customer requirements directly from the disk or printer(Need to modify the interface software)Any interface;
*USBfunction--match1GUSB flash drive1a.During the experimentUInsert the disk into the controllerUSBOn the interface,The experimental data will be automatically recordedUInside the plate,Save as*.csvdata file(Non curve chart),The sampling period can be set on the screen.useEXCELWait for the software to open and process;
*Connect to printer(select):-configure printer,The test date can be printed by setting the number of printing times according to time,set temperature,Actual measured temperature,Set humidity,Measured humidity;
*pick upPCmachine(select):--Through centralized monitoring software,Can record experimental data,inPCAutomatically display as a curve in the machine,Can be printed directly,Unrestricted recording time.The file size depends on the hard drive capacity.PCIt can also be used as an operating terminal,Realize remote monitoring.
