Safety Precautions
To use the CSD-709 safely, be sure to observe the following precautions.
▼ Precautions
 When settings are changed incorrectly during measurement with the CSD-709, correct results
may not be obtained or the equipment may malfunction and cause damage to peripheral
devices.
 Do not cause impact to the CSD-709, for example, by striking it against a nearby object.
Otherwise, the components may be damaged or the electrical circuit may fail.
 Do not press the front panel of the CSD-709 with excessive force or with the sharp edge of a
screwdriver, for example. Otherwise, panel switches may be damaged or the operability or
environmental worthiness of the CSD-709 may be impaired.
 Do not remove the case lid, remove the panel seat, or disassemble the CSD-709, except in
order to replace a fuse. Otherwise, the case or panel seat may be damaged or the operability or
environmental worthiness of the CSD-709 may be impaired.

1.3 Features of CSD-709
1.3.1 Basic functions
The CSD-709 supports the following basic functions.
The CSD-709 captures the sharp peak load more accurately by means of high-speed AD
sampling of up to 4 000 times/s, an analog low-pass filter, a digital low-pass filter, and
moving-average processing. It also supports an analog peak hold function that enables more
rapid peak capturing regardless of sampling rate.
The CSD-709 supports a simplified calibration function that starts the calibration process by
simply holding down a key. Calibration based on communication through various interfaces is
also available.
In the pre-work check, you can use preset check values to easily verify that the correct
calibration status is maintained.
The load currently applied to the strain-gage-based transducer, such as the load cell, is
displayed in mV/V, allowing you to separate abnormal values and unstable measured values.
Tracks and peaks can be output in analog form. The hold target can be flexibly selected from
displayed values and comparative outputs.
Up to four different types of calibration data or comparator settings are memorized so that you
can select the desired value by means of key operation or external control input.
You can select the peak detection mode from 36 modes configured through a combination of
nine hold modes (peak hold, bottom hold, peak-bottom hold, peak-to-peak hold, maximum hold,
minimum hold, maximum-minimum difference hold, average hold, and four inflection point holds)
and four section modes (entire section, specified section, time-specified section, and automatic
start time-specified section).
1.3.2 Addition of functions using options
The following additional functions become available through mounting options.
Current and voltage outputs synchronizing with high-speed AD sampling
Sink-type and source-type BCD outputs
Readout of loads and confirmation/change of settings by means of RS-232C interface
Readout of loads and confirmation/change of settings by means of RS-422/485 interface
Readout of loads by means of serial interface (S-I/F)
Power supply voltage in DC
External control input in voltage
Readout of loads and confirmation/change of settings by means of CC-Link interface
Utilization of PC applications through the addition of memory

1.5 Mode
The CSD-709 supports the following measurement and operating modes.
Measurement mode: You can display the value currently measured. Measurement mode is
further divided into two modes: Track mode and Peak mode. In Track mode, the value, which is
input from the measuring unit and changes with the elapse of time, is displayed in the load
window. In Peak mode, the maximum and minimum measurements are detected and held.
Function mode: You can set the functions prefixed with [F-], including the function related to the
number of AD sampling times and the measurement of the digital filter, the function related to
comparisons (e.g., operation of the comparator), and the function related to the operation of the
key lock and hold target, and check these settings.
C function mode: You can set the functions prefixed with [CF-], including the selection of
calibration number, decimal point display position, and current calibration data, and check these
settings.
P function mode: You can set the peak hold related functions prefixed with [PF-], including
determination of the detecting section and execution of detection, and check these settings.
CAL selection mode: You can select CCAL mode used for calibration, CADJ mode used for fine
adjustment of calibration results, and VCAL mode and VADJ mode used for calibration and
adjustment of optional current output and voltage output cards.
Check mode: You can check CSD-709's ROM version, mounted options, external control
operations, and the like.
COMP setting mode: You can set comparison values and check comparator settings.

1 Overview

The mode in which multiple detection operations, such as peak detection, maximum detection, and
inflection point detection, are combined to obtain the results from the load changing with the elapse
of time is called [multimode] and distinguished from operations based on a single detecting
sequence ([single mode]).

1 Overview

1.6 Basic key operation
To toggle between Measurement mode and any other mode, use the key. To move to any of
COMP setting modes from the Function mode, press the or key to change the display,
then press the key. To return to Measurement mode from any other mode, press the key
several times.
In Function, C function, and P function modes, respectively, the following numerical values prefixed
with the codes shown below are displayed.
