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 meter 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 meter.
The “MAN” icon will lit up. Set meter to display the sample
temperature by using
“Up”
and
“Down”
(0.0 to 100.0
℃
).
2.
Repeat steps 2 to 4 of
“Measurement with an ATC/Temp
probe in the pH NON- AUTOLOCK mode”
.
D. Temperature Measure
The 6179 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 (Rmv) mode. Press
“Set”
to enter the
hold/clear selection screen. Use
“Up”
or
“Down”
to select
“CLr”. Press
“Slope/Enter”
. The meter will clear all
previously stored calibration values and is now ready for
fresh calibration.
2.
Connect the ORP electrode to the BNC connector of the unit.
The “MAN”, “mV” and “AUTO” icons will lit up.
3.
Rinse the ORP probe in distilled water and immerse it in the
standard solution. Then press and hold
“Stand”
for 2
seconds to calibrate. The “CAL” & “RmV” icons will lit up.
According to the mV (RmV) value displayed, use the
“Up”
and
“Down”
keys to adjust the display value to the same
value as the standard solution. Press
“Slope/Enter”
to save
and complete the calibration.
F. mV (RmV) Measurements
a. Measurement in the mV (RmV)-AUTOLOCK mode.
1.
Connect the ORP electrode to the BNC connector of the unit.
2.
Press
“Mode”
until “mV” or “RmV” icon and “AUTO” icon lit
up.
