AUTO-LOG
Note: If logging with a model 1524 using two active probes and a 1 second interval,
a second of data will be skipped approximately every three seconds in order to have
unique values in every set of stored data. When the unit is in Auto interval sampling,
the Fast Scan Mode Specifications apply. Refer to Table 15 on page 21, Fast Scan
Mode Specifications and Table 16 on page 21, Sample Interval per Channel in Seconds
5.2.2 Sending Auto Log Data to a Computer
The data from one or all tags can be sent out the serial port to a computer. In order to
send data out the serial port, the instrument must be in the main numeric screen, and
the logging session must be turned off (no logging or graphing).The user may then
press the RECALL key and press the NEXT key to highlight the Send Logs selection,
then press ENTER.
The next menu screen will allow the user to select a specic Tag ID to download or
choose to down load All tags. Use the up and down arrow keys to make selection.
5.2.3 Data Upload Format
Each data line includes the default or the user dened Tag ID, the channel number,
the primary value with units, and time and date. Note: The time stamp is available on
model 1524 only. If only one channel is active during the logging session, only the
data for the active channel will be will be sent through the serial port. If both channels
are active, the records for each channel will alternate on the output. The output format
is shown in the following example for a two channel output:
