logger: Receiving files from non-YSI equipment requires an extra
step. You must first tell the equipment to begin sending the
file. Do this using the YSI 610 Terminal emulator. Once
the logger is trying to send the file, back out of the
Terminal emulator and select Xmodem

Sending non-YSI files to a PC can either be done by using EcoWatch and Kermit as
discussed above, or using other PC communications software.
If you are using other PC communications software, you must first tell it to begin
receiving the file. Once the other software is waiting for the file, select “Kermit 610

PC:” or Xmodem 610

PC, select the file to send and press Enter.
If file transfer repeatedly fails, there is probably a baud rate or cabling problem. Set the
baud rate for the YSI 610 in the System Setup menu. 9600 baud is typical for YSI sondes,
and YSI PC software. Set the baud rate and Com port in the Setup menu of EcoWatch for
Windows. Also check the cabling. A Null Modem cable/adapter (provided) must be used
when connecting a YSI 610 to a PC, because both devices are computers. A Null Modem
cable must not be used when connecting the YSI 610 to a YSI sonde.
7.4 CALIBRATION MODE
Most sensors need to be calibrated
occasionally. When you calibrate a sensor,
you are telling the sonde that you know the
exact value for what it is measuring. For
example, you may know the exact pH of a
solution in which the probe is immersed.
Keep in mind that although you are
interfacing with the YSI 610, it is the sonde
that is being calibrated and the results of that calibration are stored in the sonde.
All calibrations are similar. An example of
DO calibration is shown here and below.
When you enter the Calibration menu (from
the Main menu), you are presented a list of
sensors that can be calibrated.
Some sensors, like pH or nitrate, can be
calibrated using 1, 2, or 3 points. These
options are either shown separately on the
