1 Overview
The Y600-A instrument is independently developed by Yosemitech. It provides keyboard and
backlight with comprehensive functions, simple operation and brief interface. The instrument is
a portable device that can automatically recognize Yosemite's digital sensors including optical
dissolved oxygen, 4-electronic conductivity, turbidity, chlorophyll, BGA, OIW and TSS ,and can
measure, display, log. The microprocessor based meter can transmit USB signals and perform
sensor calibration easily on a single platform.
The dissolved oxygen sensor adopts the internationally leading fluorescence lifetime technology,
which is based on the quenching principle of specific substances to active fluorescence in physics.
The remarkable advantage of this fluorescence method in measuring dissolved oxygen is that it
does not consume oxygen in the measurement process, so there is no flow rate limit, no need to
preheat electrolyte, no need for maintenance and frequent calibration. The response time of
Yosemitech optical dissolved oxygen probe is as low as 30 seconds, making the measurement of
dissolved oxygen more accurate, more stable, faster and more convenient.

2 Setting-up
2.1 Configuration
2.2 Installing the batteries
The instrument is designed to operate with two lithium batteries. Please follow the steps below.
1）Unscrew the screws on the battery compartment and open it. Note: The screw can't be taken
off. That means the battery compartment cannot be opened until the screw can't be turned;
2）Inspect battery compartment and install two batteries. Please pay attention to battery
polarization marks inside the battery compartment, as shown in the figure below.
3）Close the battery compartment. Note that the sealing ring cannot fall off or be uneven. Make
sure correct direction of compartment and tighten up the screws.
