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 lit up.
2.
Press
“Mode”
key until “pH” icon lit 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 lit up. Set unit to display the sample
temperature by pressing the
“Up”
and
“Down”
keys (0.0 ~
100.0
℃
).
2.
Repeat steps 2 ~ 4 of
“Measurement with an ATC/Temp
probe in the pH NON- AUTOLOCK mode”.
D. Temperature Measure
The 6377 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 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,
“MAN”, “mV” and “AUTO” icons will lit up.
3.
Rinse the ORP probes 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” icons will lit up.
According to the mV (RmV) value displayed, press the
“Up”
and
“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.
