2. PRESENTATION
2.1. FUNCTIONS
The C.A 10001 is used to measure the pH of solutions, and
their temperature.
It is easy to use and small enough to slip into a pocket.
Its housing is waterproof.
It is calibrated by a single key press.
The temperature can be displayed in °C or in °F.
The pH reading is automatically temperature-compen-
sated (ATC).
The measurement can be frozen by pressing the HOLD
key.

3. USE
Keep your electrode in an electrolytic solution in its
bottle. Never keep the electrode in distilled water or
de-ionized water.
3.1. CHOOSING THE TEMPERATURE UNIT
The instrument must be o󰀨.
Press the and CAL keys simultaneously for more than
2 seconds.
Choose the temperature unit by pressing the HOLD key.
Save your choice by pressing CAL.
3.2. CALIBRATION
The C.A 10001 must be calibrated regularly. Every day if it
is used a lot.
Press the key to switch the instrument on.
Withdraw the storage bottle by unscrewing it.
Soak the electrode in the rst bu󰀨er solution. Completely
immerse the glass ball. For greater accuracy, start the
calibration with the pH 7 bu󰀨er solution.
Press the CAL key.
After a few seconds, the instrument detects the bu󰀨er
solution.
If the pH of the bu󰀨er solution is not exactly 7.00, you can
change it by a long press on the HOLD key. The pH will
change to 7.01, then 7.02, etc.
After 7.50, the pH changes to 6.50, then 6.51, etc.
When the instrument has determined the rst calibration
point, it saves it and exits from calibration mode.

6
The calibration ranges are:
from 3.50 to 4.50 for a pH 4.00 bu󰀨er solution
from 6.50 to 7.50 for a pH 7.00 bu󰀨er solution
from 9.50 to 10.50 for a pH 10.00 bu󰀨er solution
If the measurement is outside of these limits, or the bu󰀨er
solution is not detected by the instrument, or the electrode is
damaged, the instrument waits 10 seconds, then aborts the
calibration and displays End.
Rinse the electrode in de-ionized water.
For a calibration at 2 or 3 points, repeat the above calibration
procedure with a pH 4 bu󰀨er solution, then with a pH 10
bu󰀨er solution.
3.3. PH MEASUREMENT
Withdraw the storage bottle by unscrewing it.
Immerse the electrode in the solution to be measured.
Press the key and agitate the electrode to obtain a
stable measurement.
The temperature is displayed and the central point on
the display unit blinks while the instrument makes the
measurement.
The measurement is displayed.
The ATC symbol indicates that the pH reading is temper-
ature-compensated.
To freeze the measurement, press the HOLD key. Press
HOLD again to return to the real-time measurement.

7
At the end of the measurements, switch o󰀨 the instrument
by pressing the key. Clean the electrode with de-ionized
water and put it back in its storage bottle.
3.4. AUTO OFF
The instrument switches itself o󰀨 automatically at the end of
20 minutes of inactivity.
To disable auto o󰀨, switch the instrument on by pressing the
and HOLD keys simultaneously. The instrument displays
n. Release the keys.
Auto o󰀨 is restored the next time the instrument is switched on.
3.5. ERRORS
The instrument displays - - -
The pH is outside the measurement range. The solution is
too alkaline or too acid.
The instrument displays H or L
The temperature is outside the measurement range. The
solution is too cold or too hot.

5.1. REPLACEMENT OF THE BATTERIES

hold waste. Take them to the appropriate recycling
collection point.

5.2. CLEANING
5.2.1. HOUSING
Since the C.A 10001 is waterproof, you can clean the hous-
ing with soap and water. Do not use alcohol, solvents, or
hydrocarbons.
5.2.2. ELECTRODE
The presence of white deposits on the electrode is due to
the evaporation of the storage solution. To eliminate them,
rinse with water.
Do not use aggressive and/or abrasive products and do not
scratch the glass ball. Rinse the surface of the glass and the
external part of the junction with de-ionized water.
If rinsing is not enough, use cleaning solutions suited to the
type of contamination. Silver sulphide deposits are washed
with a solution of thiourea in 0.1mol/L hydrochloric acid.
Clogging by silver chloride can be eliminated with a concen-
trated ammonia solution. Proteins are cleaned using an acid
pepsin solution.
5.3. MAINTENANCE
Keep your electrode in an electrolytic solution in its bottle
or in another ion-rich aqueous solution in order to ensure
uninterrupted hydration of the membrane.
Do not keep the electrode dry or in distilled or de-ionized
water, since this could a󰀨ect the membrane and shorten the
life of the electrode.
Use fresh bu󰀨er solutions for each calibration.
Rinse the electrode in de-ionized water after each meas-
urement.
5.4. TROUBLESHOOTING
The instrument fails to switch on when the key is pressed.
Check that the batteries are in place and that the polarities
are correct.
Replace the batteries and try again.
Remove the batteries for one minute, then put them back
in place and try again.
The instrument responds slowly
Clean the electrode. Refer to §5.2.2.
The measurement uctuates rapidly
The electrode is not immersed far enough in the solution
or the junction is fouled. In this case, refer to §5.2.2. for the
cleaning procedure.
