Change the settings
The settings for dissolved oxygen measurements can be changed when
a dissolved oxygen probe is used. Push
1. Push . The first setting is shown.
2. Quickly use the arrow keys to change the value. Wait for the next
setting to be shown and change any additional values:
Option Description
nb Atmospheric pressure in mbar (default: 1013 mbar)
SAL Salinity in g/L NaCl (default: 0 g/L)
Note: The salinity value can be found from a conductivity measurement. Refer
to Table 3 on page 16.
Setup for conductivity
The settings for conductivity measurements can be changed when a
conductivity probe is used. Push
1. Push . The first setting is shown.
2. Quickly use the arrow keys to change the value. Wait for the next
setting to be shown and change any additional values:
Option Description
CEL Electrode type: platinum (default) or titanium.
Note: This option is not available on all meters.
tC Temperature compensation: 0 to 9.99%/°C (default: 2%/°C)
tr Reference temperature: 20 or 25 °C (default: 25 °C)
F TDS calculation factor: 0.01 to 4.44 (default: 0.64)
The new settings are automatically stored in the meter.

Calibration
Calibration procedure
This procedure is for general use with liquid calibration solutions. Refer to
the documents that are included with each probe for additional information.
1. Pour the buffers or calibration solutions into the labeled calibration
tubes.
2. Rinse the probe with deionized water and put the probe into the first
calibration tube. Be sure that there are no air bubbles under the probe
tip.
3. Push . The parameter flashes.
4. Use the arrow keys to change the parameter, if applicable.
5. Push to select the parameter.
6. Push to measure the first calibration solution.
The next calibration solution is shown.
7. Rinse the probe with deionized water and put the probe into the second
calibration tube. Be sure that there are no air bubbles under the probe
tip.
8. Push to measure the second calibration solution.
The next calibration solution is shown.
9. Rinse the probe with deionized water and put the probe into the third
calibration tube. Be sure that there are no air bubbles under the probe
tip.
10. Push to measure the third calibration solution.
When the calibration is good, the display briefly shows OK and then
goes to the standby mode.
Note: To calibrate with only 1 or 2 standards when additional standards are
supplied, push after the first or second standard is measured.
