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.

3.3 Calibration
The instrument supports DO both single-point and two-points user calibration. Single-point DO
calibration means "100.0%SAT" calibration which performed in water saturated air or air saturated
water. For best results, we strongly recommend to use air saturated water solution. Two-points
calibration consist of 100.0%SAT and 0%SAT. There is no Zero calibration here.
Press and hold the “Cal” key can quickly switch to calibration interface.
Before calibration, please move protect cap with damped sponge from the sensor cap of DO
and make sure the sensor has connected to the instrument.

One/Zero Point
Point
0%SAT DO calibration solution: take anhydrous sodium sulfite (Na2SO3) to a beaker, add 200ml of
tap water or pure water, and stir until dissolved or even precipitates crystals.
100%SAT DO calibration solution：Aerate the water with an oxygen pump and continue 15 minutes.
Then can get air saturated water solution.
* The air can be considered as saturated oxygen environment if the condition is not allowed.

Connecting to a Computer
The Y600-A instrument comes with special software called MeterRead, which is designed to
provide you access to data memory. The software is stored in the USB shipped with the goods.
Follow the instructions to install the software on your computer and connect the supplied
computer interface USB cable to the Y600-A and to a computer USB port. Then the COM PORT can
identify the port. Select the download data path and click Load. The file format is. CSV.
Remember in measurement interface where press the “Cal” key to switch to calibration

4 Maintenance
4.1 The instrument maintenance
The 600-A instrument require very little maintenance to keep it performing well. If the instrument
case needs cleaning, wipe it off with a soft cloth. Please keep the battery compartment dry during
using.
4.2 DO maintenance
Optical dissolved oxygen sensor is a maintenance free sensor, however to ensure its accuracy
specifications, we strongly recommend to perform routine maintenance based on following
schedule.
Maintenance
Frequency Recommended
Sensor clean up
Every 30 days
Sensor and DO sensor cap inspection
Every 30 days
DO sensor cap replacement
Every year
Sensor user calibration
Every 3~6 months
Moisturizing DO membrane surface
Every 30 days to Keep DO sensor storage cap wet
Maintenance Schedule:
1) Clean the sensor case：Use clean water to wash the sensor case. Then gently wipe off with
a lens cleaning tissue that has been moistened. For some stubborn dirt, please use gentle
home dish cleaner and a soft brush.
2) Clean the sensor cap surface：Please move protect cap from the sensor cap, rinse any fouling
with clean water. Please gently wipe off with a lens cleaning tissue that has been moistened if
necessary. Then install the protect cap. Do not scratch the DO membrane with nails or sharp
objects. That will cause DO membrane damage and the sensor will not work permanent!
3) Clean the sensor cap internal surface：If water vapor or dust intrudes into the sensor cap, the
cleaning steps are as follows:
i. Carefully remove the sensor cap
ii. Use clean water to wash the sensor cap internal surface
iii. You can use gentle home dish cleaner if necessary
iv. Then Followed with clean water wash
v. Dry up with lens cleaning tissue
4) Store DO Sensor Cap：Keep DO sensor storage cap wet to moisturize DO membrane surface.
Store the sensor cap inside protect cap with a piece of damped sponge. Please take off the
protect cap and keep it properly during use. Note: if the sponge is dry and lack of water,

- 18 -
deionized water or purified water can be added for wetting; if DO membrane is kept in a dry
state for a long time, it will lead to inaccurate measurement and greatly shorten the life of DO
membrane.
5) Inspect sensor cable：The cable should not be tightened in use; otherwise there is a risk of
breaking the wire. The sensor will not work normally;
6) The sensor case is inspected for damage due to corrosion or other reasons.
DO Sensor Cap replacement
1）Please turn off the power and unplug the sensor from the instrument before perform sensor
cap replacement;
2）Hold the sensor by one hand, and remove the sensor cap from the sensor by rotating the sensor
cap counterclockwise using the other hand. DO NOT USE ANY TOOLS.
3）Inspect the O-ring on the probe carefully. If damaged, replace it. Do not use tools to remove or
install o-rings.
4) Ensure the O-ring installed is clean.
5) Hold the sensor by one hand, and install the new sensor cap clockwise using the other hand.
And dry the inside surface with clean tissue. DO NOT USE ANY TOOLS.
6）After replaced, set the new characteristic parameters that came with the product to the
instrument. Please see chapter 3.3 in detail.
Do not touch the DO membrane with hand.
Do not apply any mechanical stress directly to the DO membrane (pressure, scratches, etc.)
