Electro-Chemical Devices (ECD) L20 - Manual (Page 13)

3. Rinse the pH electrode and ATC/temp probe with distilled
water and immerse in the sample to be measured.
4. Allow sufficient time for the display to stabilize. The
instrument will display the pH value of the sample at the
displayed sample temperature.
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 light up.
2. Press “Mode” key until “pH” icon light up.
3. Rinse the pH electrode probe with distilled water and
immerse in the sample to be measured.
4. Allow sufficient time for the display to stabilize. The
instrument will display the pH value of the sample at the
set sample temperature.
D. Temperature Measure
The pH6810 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
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.
