YSI Incorporated Displays and Loggers 3
SECTION 1 GETTING STARTED
The YSI Display and Logger series instruments are powerful, hand held microcomputers
that allow the user to display sonde readings, configure sondes, store and recall data,
upload data from sondes and transfer data to computers for analysis and plotting.
1.1 BATTERIES AND CHARGING
An internal NiMH battery pack powers the YSI 610. This supply is sufficient to run a
YSI 610 connected to a sonde for 6-8 hours. If the sonde is being powered separately, the
YSI 610’s batteries can last much longer. The sondes can be powered by their internal
batteries (6920, 6600 and 600XLM only), or by using a power supply such as the YSI
6038.
To ensure that you get maximum operational time from your hand-held display/logger,
the user should follow the procedures below:
1) Place your display/logger on charge for approximately 24 hours.
2) After 24 hours, take the display/logger off the charge and switch it on. Leave the
display/logger on until the battery is fully discharged.
3) Repeat steps one and two at least two more times. This ensures that the battery is
charged to its maximum capacity.
4) Do not charge the batteries for more than 48 hours.
If the above steps are not followed, it may result in limited operational time of your
display/logger and limited lifetime of your terminal’s battery pack. When the YSI 610’s
batteries get low, the YSI 610 beeps. This provides approximately a one-hour warning
before the YSI 610 will turn itself off. A wall-mount power supply is supplied with the
YSI 610 to recharge the batteries. An optional automotive cigarette lighter adapter is also
available.
1.2 CONNECTING TO A SONDE
Since YSI 6-Series sondes do not have displays or controls, users must communicate to
them with a PC or terminal and emulation device. Figure 1 is a diagram of the YSI 610
connected to any 6-Series sonde.
