When sequence controllers being used in applications such as
production and testing lines stop due to errors or generate warning output, potential causes include momentary AC power interruptions and brownouts. The MR8870 is ideal for analyzing the
operation of such systems since it can record the correlation of
sequence relay signals, AC power circuits, and DC voltage circuits
as waveforms using power
supply anomalies as a trigger.

n AC RMS data recording
Use the device in conjunction with an AC voltage input and
a clamp current sensor to record RMS values for current.
Input instantaneous waveforms are acquired via high-speed
sampling at 200 μsec. RMS data is staggered at a rate of
1000 times per second as it is computed – not even abrupt
fluctuations will escape notice.
The photo above shows the Hioki 8205-10 and 8206-10 Micro HiCorders. These
products are no longer available.
n RMS data recorded in internal memory
The RMS recorder can output data into the internal memory
RMS value calculation method
at rates of up to once per millisecond. Internal memory
RMS values for three AC waveform cycles are calculated 1,000 times
every second (see figure below). Readings other than maximum and
minimum values are eliminated based on the set recording interval,
and the resulting data is displayed and saved.
recordings of up to 10,000 div (1 million data items) are
supported. Furthermore, if you set automatic saving to
storage media, the device writes data to the media (at each
recording interval) in real time as it makes measurements.
* A new data file is created for each 10,000 div worth of data.
* It is possible to save the data repeatedly up until the media’s full capacity is reached,
but after that periods of dead time (when measurement is not possible) will occur every
10,000 div.

• If you set automatic saving of binary-format data to the CF card in the 50-ms/div-and-slower range of the
time axis, data is saved simultaneously with measurement. This considerably reduces the amount of dead
time (the period from the completion of the saving of internal memory data (of the applicable capacity below)
to the CF card, to when measurement/recording begins again). This is a new function – the MR8870 is the
first in the series to feature it.
• The possible length of a single measurement/recording is the length given below for the applicable time axis
range.
• The maximum recording length is the same whether 1 or 2 channels are used.
• The internal memory capacity is 4 MB/channel. Media capacity depends on the card (for example, 512 MB).

Precautions when connecting a high-precision current sensor to a Memory HiCorder
Connecting to the MR8880/MR8875/MR8870
• High-precision current sensor (ME15W) + CT9555 + BNC cable → MR8870
• High-precision current sensor (PL23) + CT9900 + CT9555 + BNC cable → MR8870
