display changes less than 0.01 pH within approximately
10 seconds, the autolock function will be activated.
The WAIT annunciator will stop flashing and stay off.
The reading is then locked and will not respond to
further changes from the pH electrode.
3.5 For samples that are inherently unstable, the
instrument will not autolock. Use the pH NON-AUTOLOCK
mode for measurements.
4. Measurement with manual temperature compensation in the
pH NON-AUTOLOCK mode.
4.1 Connect the pH electrode to the connector of the
instrument.
4.2 Press the [MODE] key for the LCD to display pH and for
the AUTO annunciator to be off.
4.3 Rinse the pH electrode with distilled water and
immerse it in the sample to be measured.
4.4 Allow sufficient time for the display to stabilize.
The instrument will display the pH value of the sample
at the set sample temperature.
TEMPEARTURE MEASUREMENTS
The model 6173 can be used to measure temperature
independently with the ATC/Temp probe without using the pH
electrode.
1. Place the ATC/Temp probe in the media to be measured. The
measured temperature is displayed.
2. If "Undr/OvEr" is displayed on, the temperature is out of
the temperature range of -10.0 to 120. ℃ . Once the
temperature is brought within range, then "Undr/OvEr" will
