When finished with scanning and storing, or if the limit of the memory is
reached, the data in the non-volatile memory can be downloaded through the
serial port located on the right side of the data reader. A serial cable must
connect the reader to a computer with upload capabilities. The data is
transferred by depressing the D/L button. If the reader is holding a valid
reading, and the green LED is lit, hold down the D/L button for approximately
two seconds. This is to protect against inadvertent clearing of the last reading if
it has not been stored.
To clear the non-volatile memory, power down the data reader then, while
pressing both the STORE and D/L buttons, power up the reader. Hold down
both buttons until the display indicates “#001” on the memory counter. This
procedure takes several seconds.
The display is a Liquid Crystal Display with two rows of 16 characters.
Examples of the display are shown below in Figure 1. When a valid reading is
made, the diagnostic data Hex code is first displayed. Next “XX%ALM” is
shown, where XX% is the percent to alarm of the last sample, then “#YYY”
where YYY is the next available non-volatile memory location. When the
battery runs low, a low battery message is displayed.
