- Page 2 GENERAL OxyGuard Handy Polaris TGP is a hand-held meter with built-in datalogger. It measures the Total dissolved Gas Pressure, the oxygen (DO) partial pressure and the temperature. The instrument calculates the pressure of other dissolved gases from the total pressure and DO partial pressure. It can operate in three modes: A) As a standard Polaris dissolved oxygen and temperature meter.
- Page 3 Press an arrow button to select which parameter is shown in large figures. Press "OK" to go from the measurement display to the menus. The arrow buttons can then be used to make a selection and the "OK" button to confirm or go to the next level.
- Page 4 1) Calibrate Accurate measurements need accurate calibration, which in turn needs stable conditions. Polaris TGP checks and only permits calibration if conditions are stable. The sensitivity of this check can be changed - see "Setup – Calib. Preci- sion". The “Field” setting is recommended. A good way of checking calibration is to do so in the morning before taking the Polaris into use.
- Page 5 %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.
- Page 6 Use “Log Values” to select what should be logged. The options are “Barometer”, “Rest gases”, “oxygen mg/l” and “oxygen %Vol”. Press “OK” and choose “Off or On” to select. “Max Log ID” sets the number of groups of logs the memory is divided between. Store all measurements made the same place (both one-shot and interval) Under the same ”Log ID”.
