ULTRAPEN™ PT5

MODE	METHOD OF MEASUREMENT
Hold	Displays real-time readings until stable or 3 minutes, whichever comes first, then displays final readings.
LIVE	Displays real-time readings continuously for up to 5 minutes.

MODE	PARAMETER MEASURED
DO Default	Display alternates between DO Concentration in ppm, DO Saturation in % and Temperature.
DO Concentration	Display alternates between DO Concentration in ppm and Temperature.
DO Saturation	Display alternates between DO Saturation in % and Temperature.
