7. Deleting the Weighing Data
Note: The AD-1688 performs as follows only when
connected to a weighing instrument.
Two ways of deleting data are available; deleting the most
recent data (or data with the most recent number) or all the
data. Use this to delete the incorrect data.
1. Data number display
Connect the AD-1688 to a weighing
instrument using the RS-232C cable.
When the data number appears,
press and hold the CLEAR key for
2 seconds or more.
2. Selecting a deletion mode.
The “CLR” segment turns on and the most recent data
number flashes.
Under the above condition: Release the CLEAR key to
enter the mode to delete the most recent data.
Keep pressing the CLEAR key to display “ALL”. Release the
CLEAR key here to enter the mode to delete all the data.
If the CLEAR key is kept pressed, the display indicates the
most recent data number and “ALL” alternately.
3. Deleting the data
Press the SET key to delete the designated data. The
display indicates the reduced data number.
If the SET key is not pressed within 5 seconds, the AD-1688
returns to the data number display without deleting the data.
8. Switching the Displays
8.1. Memory Utilization Rate
When the data number is displayed, press the DISPLAY key to
display the memory utilization rate.
Press the DISPLAY key again to display the data number.
8.2. Date/Time Display
When the data number is displayed, press the SET key to
display the year, date and time.
1. Data number display
2. The display indicates the year and date for 2 seconds each,
and then indicates the time.
3. Press any key to return to the data number display.
9. Function Settings
In the function setting mode, settings of the AD-1688 performance
and communication can be changed.
Each function has parameters. By changing the parameter, specify
the performance of the function.
The set parameters are maintained in memory even if the AD-1688
is disconnected from the weighing instrument or personal computer.
For easier setting, the AD-1688 Setting Tools is available for
downloading from our website.
9.1. Setting Procedure
1. Connect the AD-1688 to a weighing instrument using the
RS-232C cable.
2. When the data number appears,
press and hold the SET key for 2
seconds or more.
3. The function display appears. (Refer to “9.2. Function List”.)
Press the DISPLAY key to select a
function, and press the SET key to

9.3. Number of Data on a Line
This function is useful for storing data with different contents or
items at the same time, for example, ID and number of samples
in a counting scale. When the number is set, <CR>s of up to the
setting are converted into commas. Once the number of <CR>s
is reached the setting, a new line starts.
For example, the ID, number of samples and weight are sent
individually. Using this function, these three data items can be
placed on one line as shown in (B).
Example data received to transmit to Excel
ID,000123
<CR><LF>
QT,+00000056 PC
<CR><LF>
ST,+0003.102 g
<CR><LF>
(A) When the number of data on a line is 1, the ID, number of
samples and weight are stored on separate lines.
(B) When the number of data on a line is 3, the ID, number of
samples and weight are stored on one line.
10. Interval Mode
In the interval mode, the weighing data is stored at a certain interval.
Available intervals are:
1, 2, 5, 10, 15, 20, 30 seconds / 1, 2, 5, 10, 15, 30 minutes / 1 hour
1. Connect the AD-1688 to a weighing
instrument using the RS-232C cable.
2. Select the interval mode (
int
) for the data
storage mode (
reC
) of the function setting and
set the interval time (120 seconds in the
example). Press the CLEAR key to display the
data number. In the interval mode, the
mark turns on at the lower right.
3. Set the data output mode of the weighing
instrument to the stream mode. For details on the setting
procedure, refer to the instruction manual of the weighing
instrument.
4. Press and hold the DISPLAY key for 2 seconds or
more. The AD-1688 starts to store the data at a set
interval. The mark flashes while the data is being stored.
5. To stop storing the data, press and hold the
DISPLAY key. The mark stops flashing and
turns on.
6. Remove the AD-1688 from the weighing instrument.
7. Connect the AD-1688 to a personal computer and read the
stored data.
