KR3000 Series Graphic Recorder

KR3000 Series are network-compatible paperless recorders with high performance and high operating function employed high visibility 12.1” TFT color LCD display and touch panel operation system. High speed of sampling rate 100ms for 48 points and high accuracy of ±0.1% were realized, and measured data is stored into internal memory and maximum 2GB compact flash card (CF card). As it can be monitored by a web browser display on several computers on intranet or internet, FTP transfer of data file and E-mail notification are also available.

Large sized 12.1” TFT color LCD display
Large-sized high visibility display with various display functions. Real time/Historical trend screen, Bar-graph screen, Data screen are selectable for various applications.
Combination display for selected 4 screens is available. It is easy to switch to individual screen by touching panel.

Large capacity of data memory and various recording method
Compact flash card (CF card) slot is equipped as standard external memory. Large capacity storage of maximum 2GB is available.
Various data storing methods are selectable such as schedule programming by time of day and time of date, recording start-up by external signal and event, and data logging of before and after trigger points for alarm.

Multi points recording with high speed/high accuracy
High-speed recording of approximately 100ms for 48 points and high accuracy of ±0.1% were realized. Stable measuring and recording are possible with high speed.
High withstand voltage of 1000V AC between input channels.

Easy operating and programming without manuals
Easy operating by dedicated keys for each function and touch panel.
USB port is prepared in front compartment. Setting file and data file are stored in USB memory stick.

LAN network capability
Various networked environment such as remote monitoring by browser, FTP server, FTP client and E-mail notification are applied as Ethernet is equipped as standard.

Analyzing/data acquisition application software
It is easy to replay and edit the recorded data file. Replay display has functions of vertical/horizontal trend, circular trend, and also wave-analyzing and marking by using the cursor.
