Hach-Lange PHC10130 User Manual - Manual (Page 3)

• The meter will automatically correct the calibration measurement to the selected
reference temperature (20 or 25 °C) using the default NaCl-based, non-linear
temperature coefficient. Settings can be changed in the CDC401 Calibration Options
menu.
• The calibration is recorded in the probe and the data log. The calibration is also sent
to a PC, printer or flash memory stick if connected.
• Air bubbles under the sensor tip when submerged can cause slow response or error
in measurement. If bubbles are present, gently shake the probe until bubbles are
removed.
• If a calibration error occurs, refer to Troubleshooting on page 9.
Calibration procedure:
1. Connect the
probe to the
meter. Make sure
that the cable
locking nut is
securely
connected to the
meter. Turn on the
meter. 2. Push
Calibrate. The
display shows the
conductivity
standard solution
that is necessary
for calibration. 3. Add fresh
conductivity
standard solution
to a beaker or an
appropriate
container. 4. Rinse the
probe with
deionized water.
Blot dry with a lint-
free cloth. 5. Put the probe
in the standard
solution and stir
gently. Make sure
that the
temperature
sensor is
completely
submerged.
6. Push Read.
Stir gently. The
display will show
"Stabilizing" and a
progress bar as
the probe
stabilizes in the
standard. The
display shows the
standard solution
value that has just
been read and
shows the
temperature
corrected value
when the reading
is stable. 7. Push Done to
view the
calibration
summary. 8. Push Store to
accept the
calibration and
return to the
measurement
mode. If a rugged
probe, install the
shroud on the
probe (refer to
Install the shroud
on page 9).
