MEMORY HiCORDER 8847 For the field Professional Recorders Fully Isolated High Speed Recording, Tough Enough for the Field ■ FFT analysis function available ! ■ Increased performance now available with firmware version 2.00 that adds FFT, waveform calculation and memory segmentation functionality. New input units support pulse integration, frequency, and direct current sensor connections.
The Ideal Recorder for Field Use Features Easy Portability and Sturdy Construction
No Delay ■ A problem occurs, requiring immediate attention on site Grab the sturdy handle and go. The tough construction can take a few knocks. ■ Start measurement without reading through the manual The Help Wizard assists you to do exactly what you want. ■ Print out results on the spot Load printer paper with a simple one-touch operation. High printing speed gives you a hard copy in a snap.
What Users Want Start measuring without delay "Changing paper is a hassle, and printing speed should be faster!" No Problem! One-touch design takes the hassle out of the process. 50mm/sec print speed No more need for cumbersome and time-consuming steps such as threading the paper between rubber rollers and the thermal print head. Simply drop the paper roll in place, pull the tip out slightly, and close the door. As easy as one, two, three.
What Users Want Monitor high-speed signals "1 MS/s is too slow for observing fast pulse edges" High-speed 20 MS/s sampling provides ample margin The operation principle is the same as for a digital oscilloscope: data are stored at high speed in the high-capacity internal memory. Even with all channels operating simultaneously, sampling rates up to 20 megasamples per second (50 ns cycle) are possible. This ensures that sudden event spikes and instantaneous waveform changes are captured reliably.
What Users Want Having an X-Y recorder would be handy! "An X-Y recorder uses paper, but electronic data would be better!" No Problem! X-Y recorder with electronic recording Chart-type X-Y recorders are disappearing from the market, but they had certain advantages that are sometimes desirable. The 8847 brings them back with features such as independent pen up/ down control.
What Users Want Analyze data on a computer "I want to use a USB memory stick!" No Problem! Two types of USB 2.0 ports Measurement data can be saved manually on any generic USB memory device. LAN terminal USB receptacle A USB receptacle B * Automatic data saving as on CF card is not possible. The USB interface conforms to version 2.0 specifications. Mass storage devices can be used in the A type connector. * Due to compatibility reasons, some USB memory devices may not work.
