2 high performance instrument that ? ts in your hand ultra compact, yet easy to use actual size when powered on, the settings screen appears along with the waveform monitor, and the new settings navigator blinks. by activating the settings navigator, you can easily navigate by following the simple instructions. soon you will be operating the device like a seasoned professional. real-time waveform monitoring the help text crawls along the bottom of the screen, describing the function of the setting at the blinking cursor. the enhanced waveform monitor window with level meter display facilitates changes to settings by simultaneously displaying real-time input waveforms. the ?settings navigator? function guides operations activate the settings navigator
3 simple, intuitive operation the 8870-20 feels like a hand-held tester, yet takes waveform snapshots. it has no complicated functions - allowing you to observe waveforms quickly and increasing your work eff ciency. n easily make settings while viewing levels on the settings screen. q observe waveforms using only simple memory recorder functions. isolated inputs for safe measurements isolated analog channel inputs provide cat ii overvoltage protection safety for measurements of up to 300 v ac and dc (maximum terminal-to-ground rating). this capability enables safe simultaneous voltage measurements of inverter primary and sec ondar y and stacked bat ter y c ells without damaging the instrument. q 300 v isolation between measurement terminals and hicorder chassis q 300 v isolation between measurement terminals compact, easy-to-carry design volume and weight have both been reduced by 60% from hioki's previously most compact memory hicorder, the 8807-01, to just 40% the volume and 55% the weight. easily pack it in your briefcase to accompany you wherever you go. q only 176 mm wide, 101 mm high and 41 mm thick q weighs only 600 g even with the battery pack installed easy connection to a pc connect to a pc with the supplied usb cable to easily download data that has been automatically saved to a cf card. use the supplied dedicated application program to display and print waveforms on the pc. q easy usb 2.0 data transfer q dedicated application program for displaying and printing waveforms note: the cf card installed in the hicorder appears as a removable disk on the pc, but communication functions such as the capability to change hicorder settings from the pc are not available. floating voltage acquire and store data on a compactflash card for analysis on a personal computer data is simply saved to a cf card. when the hicorder is connected to a pc via usb 2.0, the data is quickly copied from the installed card to the pc: 20,000 waveform screen divisions transfer in about 20 seconds. waveform display and printing, and csv conversion with pc either off-line, or via usb 2.0, easily copy data to a pc. open a data file with the dedicated wave processor (pc application program) for the 8870-20, to import and print waveforms with your own arrow and f gure annotations. of course, screen data can be copied and pasted into common word and excel documents to easily create reports.
4 portable size for on-site jobs catering to a multitude of applications sequential control fault analysis momentary supply dropouts and low ac voltage are often found to be causes of abnormal interruptions and warnings from sequentially controlled devices in factory production and testing lines. for optimal operational analysis, specif y an abnormal power event as a trigger and simultaneously record waveforms of associated sequential relay signals, ac power and dc voltage systems. cb timing measurements analyze the relationships of multi-point logic signals and analog waveforms to detect timing issues that can affect power supply circuit breakers. use logic probes to record relay operations on up to four channels, or use differential probe 9322 for 440-volt power measurements and for support of cat iii and cat iv overvoltage measurement categories. when facility troubles require waveforms right away! battery operation is especially convenient in those situations where no power outlet is available. just plug in the supplied ac adapter to recharge the battery, regardless of whether the hicorder is on or off. the battery pack is automatically quick charged (auto- recharging function) whenever its capacity is depleted. a full charge provides about two hours of operation. synchronize two hicorders together for four-channel recording! for those times when two channels are just not enough, synchronize two 8870-20's using the external trigger i/o terminals (apply the trigger output from one to the external trigger input of the other). then use synchronous start to automatically record four channels of measurement data to a cf card.
5 ?there's a problem with the facility, so you need to see waveforms without full measurement instrumentation?? ? you often have to visit worksites to set up plants and facilities, but typical measurement instruments are too bulky?? record motor inrush current waveforms reliably record waveforms of motor startup current. measure current signals preferably using the 9018-10 clamp-on probe, or with the 3283 clamp on leak hitester. models 3284 and 3285 clamp on ac/dc hitesters are also ideal for dc waveform measurements. con? rm inverter output waveforms inverter performance analysis requires simultaneous observation of the high frequency carrier signal and the low frequency fundamental waveform being switched. the combination of high-speed sampling capability and high-capacity memory make these observations possible. for current waveform observations, use hioki clamp sensors capable of high-frequency measurements without direct electrical contact. capture momentary commercial power outages easily monitor the instantaneous waveform of 50/60 hz commercial power. use triggering to record unexpected waveform anomalies. capture momentary commercial power outages and voltage dips. unattended monitoring for unpredictably intermittent leakage phenomena record instantaneous waveforms of leakage current and line voltage. use out-of-window triggering to detect leakage events only when the input is outside of specif ed upper and lower limits. measurement data is saved to cf card whenever leakage phenomena occur. later, reload the data into the 8870-20 and use the cursor functions to analyze peak current values or breaker tripping events. in the automobile servicing industry analyze phenomena in ways that are just not possible with dedicated fault diagnostic instruments. the high-speed sampling capability of the 8870-20 as a compact hand-held oscilloscope provides mobility in situations that call for delicate testing, such as when performing high-level analysis or measuring specifiable phenomena. long-period recording like a pen recorder record dual-level dc voltage systems as you would with a pen recorder. use the 10 ms sampling rate to record momentary voltage fluctuations.the internal two-megaword memory offers about five hours of recording with a 10 ms sampling interval. fast, 1ms/second performance despite its compact size. isolated inputs ensure safe commercial power measurements. waveform details can be easily observed. have you ever had an experience like these?
