d. Allow sufficient time for the display to stabilize. The
meter will display the pH value of the sample at the
displayed sample temperature.
4. Measurement with manual temperature compensation in
the pH NON-AUTOLOCK mode.
a. 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”
or
“Down”
keys (-10.0 to
120.0
℃
).
b. Press
“Mode”
key until “pH”, “MAN”, “buffer” icons lit up.
c. Repeat steps 3 to 4 of
“Measurement with an ATC/Temp
probe in the pH NON-AUTOLOCK mode”.
D. Temperature Measure
The
6377MB/6377BEU
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 Offset
1. Turn the unit on. In the mV mode, press
“Clear”
key for 5
seconds, all LCD elements will lit up. The meter clears all
calibration values stored in internal memory.
2. Connect the ORP electrode to the BNC connector of the unit.
3. Press
“Mode”
key for the LCD to display “MAN” and “mV”.
The "WAIT" icon begins to flash.
4. Rinse the ORP electrode in distilled water and immerse it in
the standard solution. Then press and hold
“Stand/Cal”
key
for 2 seconds to calibrate. The “CAL”, “RmV” and “MAN” icons
will lit up. According to the mV (RmV) value displayed, press
the
“Up”
or
“Down”
keys to adjust the display value to
the same value as the standard solution. Press the
“Slope/Enter”
key to save and complete the calibration.
5. Press and hold
“Mea./Eff.”
key for about 5 seconds to
display the new electrode offset value
。
F. mV (RmV) Measurements
1. Measurement in the mV (RmV)-AUTOLOCK mode.
