1 MR8847-01 MR8847-02 MEMORY HiCORDER MR8847-03 Recorders Fully Isolated, High Speed & Tough for the Field Upgraded Multi-Purpose Memory Recorder ■ Memory capacity upgraded! Four times or eight times as large as base model of 64 M-words lets you record differing electric potential objects simultaneously Isolated inputs for all channels enhance measurement safety Record differing electric potential objects simultaneously Sturdy construction designed for use in the field Tough body and strong enclosure provide superior resistance to shocks, falls, and vibrations. Clears a 50 cm drop test. Note: Using in-house testing conditions. Absence of impairment or damage in all cases is not assured. High-speed printing for checking data right on the spot Printer features newly designed roll paper drop-in loading and one-touch setup, along with high 50 mm/s printing speed. FFT analysis and other functions FFT, waveform calculation and memory segmentation functionality. Input units support pulse integration, frequency, and direct current sensor connections. ■ ■ ■ m ■ www.hioki.com ) ISO 9001 ISO14001 JMI-0216 JQA-E-90091 HIOKI company overview, new products, environmental considrations and other information are available on our website.

3 No Delay ■ A problem occurs, requiring immdiate 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. High Speed ■ High-speed sampling up to 20 MS/s Full isolation for all channels and simultaneous sampling Save 30MB to a CF Card: Max. 40 seconds Data save speed may vary, depending on conditions. ■...

4 9 Start measuring without delay "Changing paper is a hassle, and printing speed should be faster!" Actual size of printout example Wf No Problem! Mrmnry ^ms/rl i v( 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. 82 "I need measurement results in hand right away!"

5 r What 1 Users Monitor high-speed signais W Want "1 MS/s is too slow for observing fast pulse edges" ICI-No Problem! High-speed 20 MS/s sampling provides ample margin The op)ration 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 mega-samples per second (50 ns cycle) are possible. This ensures that sudden event spikes and instantaneous waveform changes are captured reliably. ■ Semiconductor memory storage Units using hard disks or other...

6 WshearSHaving an X-Y recorder iwantf would be handy! "An X-Y recorder uses paper, but electronic data would be better !" Wf 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 MR8847 series brings them back with features such as independent pen up/down control. Because data are stored as a time-based series, electronic storage can be applied to tasks for which paper archives used to be necessary. ■ Pen up/down control Individual pen up/down control is possible during...

7 r What 1 Users Analyze data on a computer W Want "I want to use a USB memory stick!" New ICI-No Problem! Compatible to USB memory sticks Measurement data can be saved on any generic USB memory device. Automatic data saving is also available, making it more convenient to transfer data to a PC. Caution: Although USB memory sticks enable automatic data saving, for more reliable data protection, we recommend use of HIOKI CF cards, which are guar-anteed to work with the instrument.
