■ Recording Capacity
• Maximum recording time is inversely proportional to number of recording channels.
• Because the actual capacity of a CF card is less than that indicated, and because the header portion of waveform
files is not included in capacity calculations, expect actual maximum times to be about 90% of those in the table.
• "★" exceeds 1 year.
• Proper operation is not guaranteed for extended recording periods (one year or longer). This type of operation
impacts the product’s warranty period and service life.
Investigate why your office’s power
supply occasionally exhibits instability.
Check for fluctuations in low-voltage
signals such as instrumentation or
sensor output.
Measure the phase voltages for

Four channels of isolated
Cat III 600 V input
Thanks to its 14-bit, high-resolution A/D converter and the combination
of a high-sensitivity 5 mV/div range and a 5 Hz filter (for noise rejection),
the MR8880
-20 can deliver stable measurement of sensor output.
The MR8880 -20 is capable of mixed recording of RMS values,
DC voltage, and logic signals, allowing it to simultaneously record
data describing the interrelationships between equipment power
supplies and UPS output and control signals.
The MR8880 -20 provides a turnkey solution for both high-speed measurement at 1 MS/s and long-term
measurement. Its ability to measure everything from high- to low-voltage signals allows it to play an important
role in a variety of measurement scenarios.

l In addition to CF cards, the MR8880-20 can store data on handy USB
memory sticks.
l Data can be saved in real time to external media (at up to 10 kS/s).
l External media can be switched while measurement continues.
If the recording interval is set to 100 µs, media must be swapped outwithin
20 seconds.
l External media is protected in the event of an unexpected power
outage during measurement.
By backing up the internal power supply until processing to save data to the external
media completes, the instrument enables highly reliable data collection.
