F. mV (RmV) Measurements
a. Measurement in the mV (RmV)-AUTOLOCK mode.
1.
Connect the optional combination ORP electrode to the BNC
connector of the unit.
2.
Press
“Mode”
key until “mV” or “RmV” icon and “AUTO” icon
lit up.
3.
Rinse electrode with distilled water and immerse it in sample to
be measured.
4.
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
5.
When the “WAIT” icon disappears, the reading is then “LOCK”
and 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.]
b. Measurement in the mV (RmV) NON-AUTOLOCK mode.
1.
Connect the optional combination ORP electrode to the BNC
connector of the unit.
2.
Press
“Mode”
key until “mV” or “RmV” icon lit up.
3.
Rinse electrode with distilled water and immerse it in sample to
be measured.
4.
Allow sufficient time for the display to stabilize. The instrument
will display the mV (RmV) value of the sample.
G. Conductivity Calibration
Calibration setup contains six sections: TDS Constant,
Temperature Coefficient, Temperature Reference, Probe
Basic Cell Constant, Standard Solutions Calibration and K
Value Input. To access these sections:
1.
Connect the conductivity probe to the unit and turn the unit
on.
2.
In conductivity mode, allow temperature reading to stabilize,
press
“Stand/Cal”
key to enter the calibration mode. “CAL” &
“ATC” (MAN) icons appears on the LCD.
