Operating Instructions
Prior to first use with the meter, the pH electrode should
be calibrated. Refer to the pH Calibration section
of this manual for further instructions.
Power ON/OFF
Turn the meter on by pressing the POWER button. To turn the meter off,
press, hold and release the POWER button for 2 seconds.
Note: This meter can be powered by either six (6) "AA" batteries or AC
adapter (sold separately).
pH or ORP Modes
This meter offers pH and rH modes of measurement capable of measuring
0.00 to 14.00 pH and 0 to 1999 mV (rH).
pH measurements achieve better results when the temperature of the
solution being tested is known and a temperature compensation factor
is applied. This can be attained using manual or automatic temperature
compensation.
For manual temperature compensation, an external temperature probe
is not connected to the meter and the temperature of the solution under
test is manually entered. The temperature compensation value appears
on the lower part of the LCD display.
For automatic temperature compensation, an external temperature
probe is connected to the meter (R3000SD-ATC) and inserted into
the solution under test. The temperature compensation value will also
appear on the lower part of the LCD display.
pH Measurement Mode (Manual Temperature Compensation)
1. Connect the Optional pH Electrode into the pH/rH Input BNC Jack.
2. Press the FUNCTION button to select pH mode.
3. Set the pH Manual Temperature Compensation value. Refer to Setup Mode for details.
4. Place the pH electrode into the measured solution, so that the tip of
the electrode and junction are fully immersed and stir at a moderate,
uniform rate. The top of the LCD will display the pH value while
the bottom part of the LCD will display the setting for the manual
temperature compensation value.

pH Calibration
This meter has been manufactured for use with a pH electrode that generates
0mV at pH7.00 (177.4mV at pH4). If your pH electrode does not meet stated
specications or is being used for the rst time, calibration procedures are
necessary. Calibration also ensures accurate measurements. It is always
recommended to carry out a two point calibration for better accuracy.
Required Equipment for Calibration
1. pH Electrode (See Accessories and Replacement Parts)
2.
pH Buffer Solutions (See Accessories and Replacement Parts)
Calibration Procedure
1. Prepare buffer solutions for calibration. It is recommended to start
with calibration buffer pH 7.00 pH, followed by either pH 4.00 or
pH 10.00 (whichever is nearest to the expected sample value). Use
the pH 4.00 and pH 7.00 buffer solutions when measurements are
expected to be on the lower side of the pH scale. Use the pH 7.00
and pH 10.00 buffer solutions when measurements are expected to
be on the higher side of the pH scale.
2. Connect the optional pH electrode into the pH input jack
3. Turn the meter on by pressing the POWER button.

4. Manually adjust the temperature compensation value to make it
same as the temperature value of the pH buffer solution. Refer to the
Setup Mode section of this manual for instructions. For automatic
temperature compensation, plug in the optional ATC probe.
5. Rinse the electrode with distilled water to remove any residual solution.
6. Place the electrode into the pH 7.00 buffer solution, so that the tip of
the electrode and junction are fully immersed in the buffer solution,
and stir at a moderate, uniform rate. If using an ATC probe, both
probes should be placed into the solution together.
7. When calibration has stabilized, a pH value will appear at the top of
the display.
8. Press and hold both the REC and HOLD buttons until the screen
displays "PH" at the top of the screen, and "CAL" on the lower part
of the screen and release to enter the calibration mode.
9. Press the and buttons to scroll to pH 7.00 or whichever screen
matches your buffer solution.
10. Press the Enter button to save your selection.
11. Repeat steps 5 through 10 for the pH 4.00 and pH 10.00 buffer solutions.
Clearing pH Calibration Data
1. While under normal, press and hold both the REC and HOLD
buttons until the screen displays "PH" at the top of the screen, and
"CAL" on the lower part of the screen and release to enter the
calibration mode.
2. Press the and buttons to until "CLr" appears on the display.
3. Press the ENTER button to conrm and erase all calibration data.
4. The display will continuously blink while the calibration data is
being erased.
5. When complete, the meter will resume normal operation.

Frequently Asked Questions (FAQ's)
I cannot turn off my meter, do you know why?
Often times, the meter cannot be turned off because it is in recording
mode ("REC" mode). Make sure to exit that function by holding down the
REC button before attempting to turn the meter off.
Can I set an alarm to go off at a specific temperature?
The meter does not have an alarm function.

How long can I record for?
Battery life will depend on a number of factors:
• Quality of Battery
• Whether the beeper is ON or OFF
• Whether the backlight is ON or OFF
• Environmental Conditions during data logging
As a reference, using alkaline batteries with both the backlight and beeper
on while automatic data logging at a 2 second sampling rate; the batteries
lasted approx. 14 hours.
What is the exact ingredient of the rH probe storing solution?
The rH probe storing solution is made up of 30% Potassium Chloride &
70% Water.
