%O2 is the oxygen (partial) % sat value, which is the same %sat value as given by
a standard OxyGuard Polaris DO meter.
%RES is the residual gas (partial) % sat value. If the CO2 compensation is set to 0
mg/l, the CO2 partial pressure will be included in the residual pressure.
5) Show TGP %Vol
If you select this the instrument will show 20.9% O2, 79.1% RES and 100% TGP
when measuring in water that is 100% saturated with air.
6) Setup
This has 6 sub-menus:
a) User Interface
b) Compensation
c) Log Setup
d) Date & Time Menu
e) Calib Precision
f) Information
a) User Interface:
Language: The options depend on the language version.
Temperature Units: You can choose between °C and °F.
Display format % sat: You can choose with or without tenths.
Auto shutdown: The default of 2 minutes is recommended.
Light intensity: “Low” ensure longest battery lifetime.
b) Compensation:
You can se
t compensation for Salinity, the CO2 content of the water and the
relative humidity found in the air around the instrument when clalibrationg.
If you set the humidity to “0” then humidity compensation is disabled.
c) Log Setup
“Log mode”:
lets you choose one-shot or interval logging.
Use “Log interval” to set the interval time for interval logging.
