do not want to change the selected buffer set, press the
“Mode” key to exit and return to “pH Measure Mode”.

5
Note: There is no need to repeat this procedure every time
unless one decides to change the buffer settings.
pH Calibration
1. With pH on the display, press the “Mode” key for 2
seconds to enter the “pH Calibration Mode”.
2. Immerse the electrode into either pH 7.00 or 6.86 buffer
solution, depending on the Buffer Set selected. A ‘WAIT”
icon will flash. The pH/EC1030A will determine when the
calibration reading is stable.
3. When the “WAIT” icon disappears, one/first point
calibration is now complete. Press “Mode” key to exit (i.e.
only complete a one point calibration) or wait 5 seconds
for the meter to enter two/second point calibration.
4. Repeat Steps 2 and 3 for two points/second point
calibration by immersing in pH 4.01/4.00 or 10.01/9.18
buffers.
Note: For highest accuracy, perform a 2-point calibration.
5. Move to #6 for three/third point calibration or press
“Mode” to exit two point calibration.
6. Repeat Steps 2 and 3 for three/third point calibration.
7. When the “WAIT” icon disappears, the unit will
automatically return to Measure Mode.
D. Conductivity Calibration
Preparing Standard Solutions
Suitable conductivity standards are available commercially
or the user can prepare them using research grade reagents.
When calibrating, it is best to use a standard in the middle
range of the solutions to be measured.
Here are some standard solutions the user can prepare to
calibrate the conductivity sensor:
1. Standard solution of 1413 μS at 25 °C: Accurately weigh
out 0.746 grams of research grade dried Potassium
Chloride (KCl). Dissolve in 1000 mL of distilled water.
2. Standard solution of 12.90 mS at 25 °C: Accurately weigh
out 7.4365 grams of research grade dried Potassium
Chloride (KCl). Dissolve in 1000 mL of distilled water.
[Note: You can store the remaining solution in a plastic
container for one week but the air space between the cap and
the solution must be kept to an absolute minimum. Storing
the excess solution below 4 °C can increase the storage life.
If you have any doubt of the accuracy of the stored solution, a
fresh batch should be prepared.]

Conductivity Calibration
1. Press “Mode” key to enter the “Conductivity Measure
Mode”. The units will be in S/cm or mS/cm.
2. Clean and immerse the probe (at least 2” to 3” or 5 to 7 cm
from the tip) into standard solution without touching the
sides of the calibration container. Shake the probe lightly
to remove any air bubbles trapped in the conductivity
cell. Allow temperature to stabilize. The message “RANG”
(range) may appear briefly on the display indicating auto-
ranging. This is normal.
3. Press and hold the "Mode" key for 2 seconds to enter the
"Conductivity Calibration Mode". The "CAL" icon appears
on the display.
4. If needed, adjust the following conductivity settings:
TDS FACTOR:
The default factor value is 0.65. To change the TDS
factor, use the “Store” and “Scroll” keys to adjust the
value between 0.30 and 1.00. Press “Hold” key to save
the new value and the unit will automatically go into the
next calibration parameter. If the “Mode” key is pressed
instead of the “Hold” key, any changes made will be
canceled and the previous calibration settings will be
retained.
TEMP. COE.:
The unit uses the temperature coefficient to calculate
temperature compensated conductivity. The default
value is 1.91%. To change the temperature coefficient, use
the “Store” and “Scroll” keys to adjust the value between
0 and 4.00%. Press the “Hold” key to save the new value
and the unit will automatically go into the next calibration
parameter. If the “Mode” key is pressed instead of the
“Hold” key, any changes made will be canceled and the
previous calibration settings will be retained.
TEMP. REF.:
The unit uses the temperature reference value to calculate
temperature compensated conductivity. The default
value is 25 °C. To change the temperature coefficient, use
the “Store” and “Scroll” keys to adjust the value between
15°C and 25°C. Press the “Hold” key to save the new value
and the unit will automatically go into the next calibration
parameter. If the “Mode” key is pressed instead of the
“Hold” key, any changes made will be canceled and the
previous calibration settings will be retained.
5. Use the “Store” and “Scroll” keys to adjust the conductivity
value to that of the conductivity standard at 25 °C. Press
“Hold” key to calibrate. The unit displays “CAL OK” to

7
indicate a successful calibration. Conductivity calibration
is now complete and the unit will automatically switch to
the “Conductivity Measurement” mode.
E. Measure
In the “Measure Mode”, dip the meter into the test solution.
Press “Mode” key to select: pH/Temperature, Conductivity/
Temperature, TDS/ Temperature and Salinity/Temperature.
F. Hold Data
1. When the readings are stable, press the “Hold” key once
to lock the reading on the display.
2. Press the “Hold” key again to unlock reading and the unit
will return to the “Measure Mode”. The unit is now ready
for another measurement.
G. Save Data
Press and hold the “Store” key for 2-3 seconds in the “Hold
Mode” or “Measure Mode". The “SAVE” and “M-XX” icons will
appear indicating the reading has been saved and stored
in memory location XX. The unit automatically returns to
“Measure Mode”.
Note: The non-volatile memory stores up to 50 sets of data
(pH/Conductivity/TDS/Salinity and temperature) even if
power is lost. If the memory is full, the next set of data will
overwrite the first data set stored, etc.
H. Recall Data
1. In "Measure Mode" with Conductivity, TDS, or Salinity on
the display (i.e. not pH on the display), press and hold the
“Scroll” key for 2-3 seconds. The “REC” icon appears on
the LCD and the last set of saved data will appear.
2. By pressing the “Store” or “Scroll” key, previously saved
data sets will appear on the display.
3. Press “Hold” to exit and return to “Measure Mode”.
I. Erase Data
1. In “Recall Data Mode”, press “Mode” to enter “Erase Data
Mode”.
