DO NOT
place the sensor(s) directly into the buffer bottle. Discard
the used buffer after use.
9. When the reading has stabilised, press and hold the
key for 2
seconds to calibrate. If a 1 point calibration has been performed, a “
“
will not be removed until a full 2 point calibration has been performed.
10. Rinse the pH sensor in distilled water and blot dry.
11. Place the pH sensor into a small sample of pH4.01, pH9.18 or
pH10.01 Buffer, so that the bulb and reference junction are both
covered, as per the diagram in step 8.
DO NOT
place the sensor
directly into the buffer bottle. Discard the used buffer after use.
pH9.18 and pH10.01 buffers are unstable once the bottles have
been opened. Discard immediately after use
.
12. When the reading has stabilised, press and hold the
key for 2
seconds to calibrate. The “
“ will now be replaced by a decimal
point, if calibration was successful.
13. The
Aqua-DP
is calibrated for pH and is ready for use in this mode.
