4. PH CALIBRATION PROCEDURE
4-1 Calibration Consideration
The most ideal PH ELECTRODE generates 0 mV at PH
7.00 ( 177.4 mV at PH 4 ) and YK-2001PH has been
always calibrated with signals which simulate the most ideal
PH ELECTRODE ( based on 25蚓 ambient environment
). However not every PH ELECTRODE is as accurate as
the most ideal one, so calibration procedures are
necessary to be done before the first time measurement.
In addition to the first time measurement, users are also
recommended to execute the calibration procedures to
ensure the high accuracy measurement.
4-2 Required Equipments for Calibration
1) PH ELECTRODE ( optional ).
2) PH buffer solutions ( optional ).
4-3 Two Points Calibration Procedure
1) Power on the instrument by pressing the " Power
Button " ( 3-2, Fig. 1 ).
2) Press the " PH/mV Button " ( 3-6, Fig. 1 ) to let meter be
operated under the PH function with a " PH " symbol on the
display.
3) Adjust the " Temperature Compensation Value " to make
it same as the temperature value of the pH buffer
solution.
Manual temperature compensation value adjustment
procedure, please refer to 5-1 (Page 10).
Automatic temperature compensation value adjustment
procedure, please refer to 5-2 (Page 14).
7
4) PH 7 calibration
Connect the PH ELECTRODE with the " BNC socket "
( 3-10, Fig. 1 ) and immerse the electrode in the PH7
buffer solution.
Press the " CAL Button " ( 3-8, Fig. 1 ) then the upper
display shows texts of " CAL " and the lower display
shows the default calibration value.
CAL
7.00
* The texts " CAL " will flash for around 5 seconds.
After that, the meter calibrates itself automatically.
The upper display will show the calibrated value,
the lower display will show the temperature value.
7.00
25.0
5) PH 4 or PH 10 calibration
Rinse the electrode with distilled water.
Immerse the electrode in the PH4 buffer solution ( or PH10
buffer solution ).
Press the " CAL Button " ( 3-8, Fig. 1 ) then the upper
display shows texts of " CAL " and the lower display
shows the default calibration value.

CAL
4.00
* The texts " CAL " will flash for around 5 seconds.
After that, the meter calibrate itself automatically.
The upper display will show the calibrated value,
the lower display will show the temperature value.

25.0
6) Rinse the electrode with distilled water again.
7) Repeat above (4) to (5) procedures two times at least.
8) The instrument and electrode are now finished the
" TWO POINTS CALIBRATION " & ready for the
measurement.
4-4 Singal Point Calibration
If PH4 and PH10 buffer solution are not available, single
point (PH7) calibration can be executed from procedures
of 4-3 (1) to (4). However for more accurate measuring
result and linearity, two points calibration is always
recommended.

4-5 Others
*
*
Above calibration procedures effect only when reading value
within 1 PH of the calibration point.
However if the reading value beyonds
*1 PH of PH 7 ( > PH8, < PH6 )
1 PH of PH 4 ( > PH5, < PH3 )
1 PH of PH 10 ( > PH11, < PH9 )
the calibration procedures are :
1) Connect the PH ELECTRODE to the " PH BNC Input
Socket " ( 3-10, Fig. 1 ).
2) Power on the instrument by pressing the " Power
Button " ( 3-2, Fig. 1 ).
3) Press the " PH/mV Button " ( 3-6, Fig. 1 ) to select
the PH function with a "PH" symbol on the display
4) Set the " Manual temperature compensation " value to 25 蚓
refer to 5-1 calibration procedures, page 11.
5) Place the electrode into the standard solution ( PH7, PH4 or
PH10 ) , then the instrument will have the PH value on the
display.
6) * For measuring the PH7 standard solution, adjust the
PH 7 VR ( 3-15, Fig. 3 ) until the display value
within PH6 to PH8.
* For measuring the PH4 standard solution, adjust the
PH 4 VR ( 3-16, Fig. 3 ) until the display value
within PH3 to PH5.
* For measuring the PH10 standard solution, adjust the
PH 10 VR ( 3-16, Fig. 3 ) until the display value
within PH9 to PH11.
7) The following calibration procedures will be same as 4-3
( page 7 ) and 4-4 ( page 9 ).
