Using the AD-1688
When operating this instrument, be sure to observe the following:
Caution
• Do not open the case to repair the AD-1688. Only qualified
personnel can do that. Attempting repairs yourself may
cause damage to the AD-1688. Damage caused by
attempting to do the repair yourself will void the warranty
.
Precautions on Usage
Caution
• With the cap attached over the connectors, the
AD-1688 is protected against water splashing
(equivalent to IP65). Please note that it will not endure
immersion in water or high pressure running water.
• The AD-1688 is supplied power and is turned on only
when it is connected to a weighing instrument or the
USB of a personal computer.
1. Introduction
This manual describes how the AD-1688 works and how to
get the most out of it in terms of performance. Please read
this manual completely before using the AD-1688.
2. Unpacking
When unpacking, confirm that everything is contained.

When the AD-1688 is in use, the cap
can be attached on the bottom.
Each side has an opening. Use the
openings as follows.
A: Attach a strap to carry.
B: Connect the cap and the main unit so
that the cap will not be lost.
3. Features
• When connected to the RS-232C interface of a weighing
instrument, the AD-1688 can store the data that the weighing
instrument outputs. Thus, storing weighing data is possible in an
environment where a personal computer can not be used.
• The AD-1688 has an internal clock. This allows the date and
time to be stored, along with the weighing data.
• The maximum data to be stored is approximately 5000, using the
A&D standard format (15 characters in 1 data set).
• The stored data can be read to a personal computer using USB.
As the AD-1688 is recognized as USB memory, special software
is not required to read the data.
• The data is stored in CSV format and can be used easily by
software such as EXCEL.
• As power is supplied to the AD-1688 from the weighing
instrument or USB, no special power source is required.
Note: The AD-1688 is supplied power and is turned on only
when it is connected to a weighing instrument or the
USB of a personal computer.

6. Storing the Weighing Data
6.1. Basic Operation
1. Connect the AD-1688 to a weighing instrument using the
RS-232C cable.
Note: When the weighing instrument and a personal computer
are connected simultaneously, communication with the
computer has priority. Data storage will not be performed.

the RS-232C connector of
the weighing instrument.
When the cable is connected, power
is supplied to the AD-1688 and the
weighing data number appears.
2. Press the PRINT key of the weighing instrument to
transmit the data to the AD-1688.
When the data is stored in the AD-1688, a
buzzer sounds and the data number increases.
3. Repeat step 2 as necessary.
4. When the number of data necessary is stored,
disconnect the AD-1688 from the weighing
instrument.
The display of the AD-1688 turns off.
Note: During the data storage operation, do not remove
the RS-232C cable.
5. Connect the AD-1688 to the
USB port of a personal computer.
Use the USB extension cable as
necessary.
When connected for the first time,
a driver is installed automatically.
The AD-1688 is recognized as a removable disk.
No special software is required.
6. Open the removable disk using Windows explorer.
The data is stored in a file named “AD-1688.csv”.
Copy this file into the personal computer to use.
An example of the data opened using EXCEL is shown below.
Note: ###### may appear in column B.
To display the date, broaden the column width.
