Real-Time waveform monitoring
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.
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.

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.

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.
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

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, specify
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 t wo 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.

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 specified upper and lower limits. Measurement
data is saved to CF card whenever leakage phenomena occur. Later,
reload the data into the
8 870 - 2 0 a n d u s e t h e
cursor functions to analyze
peak current values or
breaker tripping events.
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
C L A M P O N AC/ D C
HiTESTERs are also
ideal for DC waveform
measurements.
Confirm 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.
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.
Capture momentary commercial power outages
Easily monitor the instantaneous waveform of 50/60 Hz commercial
power. Use triggering to rec ord
unexpected waveform anomalies.
Capture momentary commercial power
outages and voltage dips.
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.
