d. Measurement with manual temperature compensation in
the pH NON-AUTOLOCK mode.
1. Connect the pH electrode to the BNC connector of the unit.
The “MAN” icon will lit up. Set unit to display the sample
temperature by pressing the up and down keys(0.0 to 100.0℃).
2. Repeat steps 2~4 of “Measurement with an ATC/Temp
probe in the pH NON- AUTOLOCK mode”.
D. Temperature Measure
The pH6715 can measure temperature independently with the
ATC/temp probe without using the pH electrode. Place the
ATC/temp probe in the sample. The unit will display the measured
temperature.
E. mV Measurements
a. Measurement in the mV-AUTOLOCK mode.
1. Connect the optional combination ORP electrode to the BNC
connector of the unit.
2. Press “Mode” key until “mV” icon and “AUTO” icon lit up.
3. Rinse electrode with distilled water and immerse it in sample to
be measured.
4. Press the “Mea.” key. The “WAIT” icon will start flashing. The
unit is waiting for a stable reading. The display will track the
mV value as sensed by the ORP electrode
5. When the “WAIT” icon disappears, the reading is then “LOCK”
and will not respond to further changes from the sample. The
mV value is the sample reading.
[Note: For samples that are inherently unstable, the unit will
not AUTOLOCK. In this case, use the pH NON- AUTOLOCK
mode for measurements.]
b. Measurement in the mV NON-AUTOLOCK mode.
1. Connect the optional combination ORP electrode to the BNC
connector of the unit.
2. Press “Mode” key until “mV” icon lit up.
3. Rinse electrode with distilled water and immerse it in sample to
