650 MDS
Section 3
YSI, Incorporated Drinking Water Monitoring Systems Operations Manual
3-19
YSI suggests that the user become familiar with the features provided in the list below prior to using the
650 in field applications. Each item is described in some detail below.
3.3.1 Software version
The software version of your 650 is shown in the first line of the
System setup
menu. As enhancements
are introduced to the 650, you will be able to upgrade your 650 from the YSI web page. This item will be
used to track those upgrades and will be useful to YSI Customer Service personnel if you have questions
about the function of the instrument.
3.3.2 Date and time:
As described above in Section 3.2.8, activate this selection to set the date and time from the 650 keypad.
3.3.3 Power sonde:
If this choice is active, your 6-series sonde will be powered directly from the 650 batteries. The choice
MUST be active if you are using a sonde with no internal batteries (600R, 600XL, or 6820). If using a
sonde with internal batteries (600XLM, 6920, 600 OMS battery version, or 6600), you can extend the life
of your 650 batteries by deactivating this selection. Note that the selection MUST BE OFF in order to
determine the voltage of the internal batteries of sondes – important information for Unattended studies.
3.3.4 Baud rate to sonde:
This entry allows the user to adjust the baud rate for communication with the sonde. It does not affect
communication for upload of files to a PC. Highlight the entry and press
Enter
. Then select the baud rate
of choice and press
Enter
to confirm it.
CAUTION:
The baud rate for the 650 MUST match that in the
sonde (usually set at 9600) or communication with the sonde will not be possible. Unless you know that
your sonde is set to a baud rate different than 9600, YSI strongly recommends that you leave the baud rate
for the 650 set to the default value of 9600.
3.3.5 Shutoff Time:
This value represents the number of minutes until the 650 automatically shuts down to save batteries.
Values can be integers from 1 to 15 or enter “0” to disable the shutoff completely.
3.3.6 Comma radix:
The user can toggle between a period (default) and comma for the radix mark by selecting this item and
pressing the
Enter
key. If you change your radix mark in the 650, make sure that you also change it to the
same symbol in the sonde
