2. Connect the ORP electrode to the BNC connector of the unit.
3. Press
“Mode”
key for the LCD to display “MAN”, “mV” and
“AUTO” icons will lit up. The "WAIT" icon begins to flash.
4. Rinse the ORP probe in distilled water and immerse it in the
standard solution. Then press and hold
“Stand”
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”
key 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.
a. Connect the optional combination ORP electrode to the
BNC connector of the unit.
b. Press
“Mode”
key until “mV” or “RmV” icon, “MAN”,
“AUTO” icons lit up. The "WAIT" icon begins to flash.
c. Rinse the ORP electrode with distilled water and immerse it
in sample to be measured. Remove any air bubbles
trapped around the electrode by shaking or stirring the
electrode.
d. Press the
“Mea./Eff.”
key. The “WAIT” icon will start
flashing. The unit is waiting for a stable reading. The
display will track the mV (RmV) value as sensed by the
ORP electrode.
e. When the “WAIT” icon disappears and the “LOCK” icon
appears, the meter will not respond to further changes from
the sample. The mV (RmV) value is the sample reading
[
Note:
For samples that are inherently unstable, the unit
will not AUTOLOCK. In this case, use the mV (RmV)
NON- AUTOLOCK mode for measurements.]
2. Measurement in the mV (RmV) NON-AUTOLOCK mode.
a. Connect the optional combination ORP electrode to the
BNC connector of the unit.
b. Press the
“Mode”
key until “mV” or “RmV” and “MAN”
