5. UP or DOWN Keys
While measuring in any parameter, the or keys activate
the Memory Store and Memory Recall functions.
While in CAL mode, the keys step or scroll the displayed value up or
down. A single press steps the display and holding either key scrolls the
value rapidly.
While in Memory Recall, the keys scroll the display up and down through
the stack of records (ref. Memory Recall, pg. 19).

A. Maintenance of the Conductivity Cell
Rinse out the cell cup with clean water. Do not scrub the cell. For oily
films, squirt in a foaming non-abrasive cleaner and rinse. Even if a
very active chemical discolors the electrodes, this does not affect the
accuracy; leave it alone. (ref. Cleaning Sensors, pg. 28)
B. Maintenance of the pH/ORP Sensor
The sensor well must be kept wet with a solution. Before replacing
the rubber cap, rinse and fill the sensor well with Myron L pH Sensor
Storage Solution. If unavailable, you can use an almost saturated KCl
solution, pH 4 buffer or at least a strong table salt solution. NEVER USE
DISTILLED WATER. (ref. pH and ORP Practices, pg. 18).
V. SPECIFIC RECOMMENDED MEASURING
PROCEDURES
If the proper solution is not selected (KCl, NaCl, 442), see Solution
Selection, pg. 11.
NOTE: After sampling high concentration solutions or temperature
extremes, more rinsing may be required. When sampling low conductivity
solutions, be sure the pH cap is well seated so that no solution washes
into the conductivity cell from around the pH cap.
A. Measuring Conductivity & Total Dissolved Solids (TDS)
1. Rinse cell cup 3 times with sample to be measured. (This
conditions the temperature compensation network and
prepares the cell.)
2. Refill cell cup with sample.
3. Press or .
4. Take reading. A display of [- - - -] indicates an overrange
condition.
