“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.
Confi 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 specifi 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.
