Thank you for purchasing the HIOKI Model MR8875 Memory HiCorder. This Measurement Guide includes
basic examples of how the instrument is used. Please read it carefully before using the instrument.

Convenient functions (p.18), measurement examples (p.19), and reference information (p.21)

The Waveform screen allows you to view measurement data, while the 
Settings screen allows you to configure various instrument settings. 

Basic settings can also be configured on the Waveform screen’s 
settings windows. (This manual covers the settings that can be 
configured on the Waveform screen in its description of how to op-
erate the Waveform screen.)

Be sure to read the "Operating 
Precautions" and "3.3  Pre-Mea-
surement Inspection" se
ctions of 
the instruction manual before us-
ing the in-
strument.

Configure measurement conditions.

Configure input channels.

Configure triggers (identification conditions).

Configure data saving, calculations, and other settings as neces-
sary.
If you wish to save data or perform calculations automatically after 
starting measurement, these settings must be configured before 
measurement. Data can be saved in a variety of formats, and cal-
culations can be performed after measurement. 

Alternately, recording 
stops when the set condi-
tions are satisfied. 

This section describes operations and analytical methods that are 
frequently used on the Waveform screen.
