SN-41 Introductions:
This data logger can measure and store 4~20mAcurrent readings automatically. The professional applications can be providedby the PC software DGraph. Logger status, alarm indication and low batteryindication are via flashing red/green LED and yellow LED. The button on housingcan be used to start logging, or confirm and clear LED alarm when LED alarm ishold status.
User can plug datalogger straight into PC’s USB port without any cables. Before getting started,user need to install USB driver and DGraph software, provided on the CD whichis included in product packing box. All the software can run under Windows XP,Vista, 7 or 8(32 bit and 64 bit Versions). User can easily use DGraph softwareto setup sample rate, high/low alarm limit and start/stop method, and downloaddata to PC, etc.. And then user can view, analyse and print the data, or exportother file formats (txt, xsl, csv, bmp, jpg).
Especially, forsome professional applications, user can set access password, name eachchannel, enable/disable specified channel, input calibration data for eachchannel, disable LED indication for saving power, and select samplemode(Instant, Average, Maximum and Minimum), etc..
