5) Rinse the electrode in the distilled water.
Place the electrode into the PH-04 ( or PH-10 ) buffer
solution. Use the screw to adjust the " PH 4 calibration
VR " (3-12, Fig.1) until the display reading reach to
4.00 0.01 ( or 10.00 0.01 for PH-10 ).
6) Rinse the electrode in the 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 Single Point Calibration
1) Power on the instrument by pushing the " Power On/Off
Button " (3-2, Fig.1).
2) Select the " Function Switch " (3-11, Fig.1) to the
" PH MANUAL TEMP. " position.
3) Connect the combination PH ELECTRODE to the "
BNC socket " (3-15, Fig. 1) and place the electrode into
the PH-07 buffer solution.
Use the screw to adjust the " PH 7 calibration VR " (3-9,
Fig.1) until the display reading reach to 7.00 0.01.
4) Repeat above (3) procedures two times at least.
5) The instrument and electrode are now finished the
" SINGLE POINTS CALIBRATION " & ready for the
measurement.
5. PH TEMPERATURE COMPENSATION
Enables the meter to read solutions at various tempera-
tures. The meter corrects for an electrode's temperature
dependency. The compensation may be manual with a
button adjustment on the meter, or it may be automatic
with a optional temperature sensing probe immersed in
the test solution.
