LCD DISPLAY
Full Display
Using D.O. probe
1. The DO value will be displayed on the left side of the LCD.
2. The temperature value will be displayed in the upper right corner of the LCD.
3. The MEMO number will be displayed in the lower right corner of the LCD and is
the total number of saved records.
PAGE 6
Using pH probe
1. The pH value will be displayed on the left side of the LCD
2. The temperature value will be displayed in the upper right corner of the LCD.
3. The MEMO number will be displayed in the lower right corner of the LCD and is
the total number of saved records.
Using Conductivity/TDS/Salinity probe
1. The conductivity value will be displayed on the left side of the LCD.
2. The temperature value will be displayed in the upper right corner of the LCD.
3. The MEMO number will be displayed in the lower right corner of the LCD and is
the total number of saved records.
4. Press “EC mode” key to switch the display to TDS or salinity reading.

OPERATION
Note: Please turn the power off before replace the probe. Turn the power on after
the probe is plugged and screw tightly.
START UP
1. Install the batteries into the meter.
2. Read the section of calibration and Setup and take necessary action first.
3. Three probes which can be connected to the meter: PH probe with black
connector, D.O. probe with green connector, COND./TDS/Salinity probe with
blue connector.
The charts below indicate the electrode and temperature sensor location.
All probes are provided with an anti-collision hood to provide protection in measuring.
Please remove protection hood in below condition:
1. To store pH probe.
2. To do pH calibration.
There is installation guide between probe plug and meter socket. Find the guide, screw
probe tight moderately.
PAGE 8
Put on anti-collision hood to provide better protection. There is no need to remove
hood even during calibration.
Step 1
Press the power on key. Select fast or slow. The D.O. will be displayed on the LCD
with mg/I unit.
Two D.O. Activation modes are provided: Slow and Fast. Meter is default at Fast but it
is programmable in setting mode P6.4 (page 13)
•If D.O. probe is unplugged from meter and not in use for long time, it might take
about 10 minutes to activate.
•If D.O. probe is plugged on meter for most of time, to set the activation mode to
Fast can make the reading stabilized in few seconds. The disadvantage of Fast
mode is electrolyte consumption is much higher so the need to refill and doing
probe maintenance is frequent.
•If D.O. probe is plugged on meter for most of time, to set the activation mode to
Slow can make the reading stabilized in 10 minutes. The advantage of Slow
mode is electrolyte consumption is lower and less maintenance work to do.
Step 2
Run 100% calibration in air. (Refer to pg. 18)
Step 3
Switch from % to mg/L then dip the probe into the sample. Making sure the electrode
tips is totally immersed when you stir it.
DISSOLVED OXYGEN MEASUREMENT

Step 4
Wait until the reading is stabilized, then take a new measurement.
If your application is to measure dissolved oxygen in aqua farm, it is suggested to
measure at least 1 meter deep and do it regularly at fixed time, fixed location and fixed
water deep to get proper data for comparison.
This meter is designed with automatic temperature compensation feature. Please
remove the pH electrode soaker bottle on the electrode before use.
Step 1
Rinse the probe with de-ionized or distilled water before use in order to remove any
impurities adhering on the probe. If the electrode is dehydrated, soak it for 30 minutes
in KCI solution before taking the reading. Then, put on anti-collision hood for better
protection.
Step 2
Press power on key. Run calibration. (Refer to pg. 19)
Step 3
Dip the electrode into the sample, the electrode must be completely immersed into the
sample. Stir the probe gently to create a homogenous sample and shorten the
stabilizing time. Be careful, don’t create air bubble.
Step 4
Wait until the reading is stabilized.
PH MEASUREMENT
PAGE 10
Please put on anti-collision hood to provide better protection. There is no need to
remove hood even when you plan to do calibration. (Refer to pg. 20)
Step 1
Rinse the probe with de-ionized or distilled water to remove impurities adhering on the
electrode. If the meter is not used for a long
time, please soak the probe in clear water for
more than 30 minutes to eliminate the inert
effect of the probe.
Step 2
Press power. Making sure the electrode tip is
totally immersed. Stir the probe gently to create
a homogenous sample. Be careful, don’t create air bubble.
Step 3
Wait until the reading is stabilized.
Take a new measurement.
Under normal mode, please connect the Cond. probe to the meter. Press “EC mode”
key to switch to SALT display. Please follow the above conductivity measurement step
1-4 to take the salinity measurement.
Under normal mode, please connect the Cond. probe to the meter. Press “EC mode”
key to switch to TDS display. Please follow the above conductivity measurement step
1-4 to take the TDS measurement.
