Overview
The Hioki LR8431-20 Memory HiLogger is a compact, lightweight, easy-to-
operate waveform recorder. It can run on batteries, and can be quickly
deployed when a power anomaly occurs.
Measurement data can be monitored, subjected to calculations and analyzed
on a personal computer using the supplied application program.

1.1 Product Overview and Features
Record anomalies
Abnormal events can be ana-
lyzed by recording with the
trigger function (p. 67)
Use the alarm function to out-
put signals when anomalies
occur (p. 73).
Measurement data and
setting configurations are
stored, read and managed
as data files
Measurement data can be stored
to and read from a CF card or
USB flash drive (p. 91).
Waveform analysis
mV A
Cursor Measurements (p. 84)
A
B Using the A/B cursors, values at cursor lo-
cations on waveforms and the time at trig-
ger positions can be displayed.
Performs six calculation types, including
maximum and average values.

Display in converted units
Using the scaling function, input val-
ues can be displayed in units of the
actual physical quantity being mea-
sured, such as current or flow vol-
ume (p. 58).
Observe voltage fluctua-
tions and temperature
changes
Just connect measurement
leads or thermocouples to mea-
sure as needed.
