Atc/Temp Probe, Ph Non-Autolock Mode; Manual Temperature Compensation, Ph Non-Autolock Mode; Temperature Measure; Mv Measurements - ECD L20 Instruction Manual

c. Measurement with an ATC/Temp probe in the pH NON-
AUTOLOCK mode
1. Connect the pH electrode to the BNC connector and the ATC/Temp
probe to the ATC/Temp connector of the unit. The "ATC" icon will
light up.
2. Press "Mode" key until "pH" icon lights up.
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.
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 light up.
2. Repeat steps 2~4 of "Measurement with an ATC/Temp probe in the
pH NON-AUTOLOCK mode".
D. Temperature Measure
The L20 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
