• Connect the cap and the main unit so that the cap will not be lost.

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 cannot 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.

Function List

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, s of up to the setting are converted into commas. Once the number of 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

• When the number of data on a line is 1, the ID, number of samples and weight are stored on separate lines.
