The following documents are provided with Model 8860 and 8861 Memory
HiCorders.
Refer to them as appropriate for your application.
Which input module and cables to use with the instrument depend on your mea-
surement application. Refer to this as appropriate for your application. (⇒p. 3)
• In this document, the “instrument” means the Model 8860 or 8861 Memory
HiCorder.
• “Clamp” refers to one of our optional clamp-on sensor products.
Introduction
Document Description
1Quick Start Manual Read this first.
It describes preparations for use, basic operating pro-
cedures and usage methods.
2Input Module Guide
(This document)
To connect input modules and measurement
cables, and when making input channel set-
tings;
this Guide describes the optional input modules, relat-
ed cable connection procedures, and their settings
and specifications.
3Instruction Manual To obtain setting details;
this Manual describes details of the functions and op-
erations of the instrument, and its specifications.
4Analysis Supplement The supplement describes usage of the cal-
culation functions to analyze measurement
data.

Introduction
2
The following symbols in this manual indicate the relative importance of cautions
and warnings.
Accuracy We define measurement tolerances in terms of f.s. (full scale) values, with the
following meanings:
f.s. (maximum display value or scale length)
The maximum displayable value or scale length. This is usually the name of the
currently selected range.
In this instrument, the maximum displayable value is the range (V/div) times the
number of divisions (20) on the vertical axis.
Example: For the 1 V/div range, f.s. = 20 V
Safety Symbols
In the manual, the symbol indicates particularly important informa-
tion that the user should read before using the instrument.
The symbol printed on the instrument indicates that the user
should refer to a corresponding topic in the manual (marked with the
symbol) before using the relevant function.
Indicates DC (Direct Current).
Indicates AC (Alternating Current).
Indicates both DC (Direct Current) and AC (Alternating Current).
Indicates a grounding terminal.
Indicates that incorrect operation presents an extreme hazard
that could result in serious injury or death to the user.
Indicates that incorrect operation presents a significant hazard
that could result in serious injury or death to the user.
Indicates that incorrect operation presents a possibility of
injury to the user or damage to the instrument.
Indicates advisory items related to performance or correct
operation of the instrument.
Other Symbols
Indicates the prohibited action.
(⇒p. ) Indicates the location of reference information.
Indicates quick references for operation and remedies for troubleshoot-
ing.
*Indicates that descriptive information is provided below.
