PREPARING FOR SAMPLING:
1.
Turn on the meter by pushing the power
key . (To turn off the meter, hold down
the power key for 1.5 seconds.) If the meter
does not turn on, inform the team leader and
see the “Settings and Troubleshooting”
section under “Battery Troubleshooting”.
2. The main display, or “Run” screen, will
appear. Take note of the battery charge at
the top right, displayed as a percentage. If
the charge is low, inform your team leader.
Charging the Internal Li-Ion Battery Pack
Use YSI designated charging equipment only!
If the battery is not charged, the meter must be
charged from the AC power adapter
(strongest
charge source)
, directly from a computer USB
connection, or from an external, portable USB
battery pack. When using the AC adapter, turn
the unit on first so it recognizes the AC adapter.
Once the charging signal appears on the screen,
it can be turned off. It takes approximately 14
hours to charge the ProDSS battery with the unit
turned off. For maximum battery life, if practical,
don’t charge until the battery is ≤40%, and bring
the battery back up to ≥80%.
Expected battery life:
• 20 hours at 25% (default) LCD brightness
• 14 hours at 100% LCD brightness
Study the main “Run” screen. Confirm the
following:
•
The battery charge is >10%. If not, inform
your team leader.
•
The date and time are correct:
The date and time should be displayed at
the top of the screen; if not, refer to the
“Settings and Troubleshooting” section
under “Date/Time”.
•
Logging is correct:
At the top of the screen in the green bar,
it should read “Log One Sample”; if not,
refer to the “Settings and
Troubleshooting” section under “Logging
Data”.
•
Individual parameter units are correct:
temperature - °C
barometric pressure – inHg
dissolved oxygen concentration –DO mg/L
specific conductivity (at 25 °C)–SPC µS/cm
salinity – SAL ppt
pH
turbidity – FNU
If any parameters shown above are not
displayed or do not match the units on the
Run screen (see photo below), notify your
team leader and refer to the “Settings and
Troubleshooting” section under “Sensor
Display Details”.
