4. Press any parameter key to exit ORP unit preference selection
or let the unit time out. ORP unit preference will be saved.
2. Measuring ORP
1. Ensure the 9P is in ORP mode (ref. ORP/FC
E
Mode Selection,
pg. 20).
2. Remove protective cap by rotating while grasping and pulling up.
3. Rinse sensor well and cell cup 3 times with sample to be
measured. Shake out each sample to remove any residual liquid.
4. Refill both sensor well and cell cup with sample.
5. Press .
6. Take reading.
7. Press MS to store reading in memory, if desired.
IMPORTANT: The sensor well must be kept wet. Before
replacing the rubber cap, rinse and fill the sensor well with

J. Measuring Free Chlorine Using FC
E
The FC
E
function can be used to measure flowing solution, bodies of
water and discrete samples. The measurement techniques are unique
to each type of sample. For best results, use the FC
E
Flow Method or
the FC
E
Immersion Method. For discrete samples, follow the FC
E
Flow
method, but instead of a running stream, rinse the conductivity cell cup
and pH sensor well three times then fill with the sample to be tested.

E
Best Practices before you begin.
1. Prepare for FC
E
Measurement
1. For ease of measurement, set the instrument’s Auto oFF feature
to 75 sec (ref. AUTO OFF, pg. 43).
2. Ensure the FC
E
mode has been activated (ref. ORP/FC
E
Mode
Selection, pg. 20).
3. Remove protective cap from the pH/ORP sensor by rotating
while grasping and pulling up.
2. FC
E
Flow Method
1. Empty the pH/ORP sensor well of all storage solution.
2. Hold the 9P at a 30º angle (cup sloping downward).
3. Thoroughly flush the pH sensor well and conductivity cell cup
with a steady stream of the solution you intend to measure by
allowing the solution to flow into and out of the sensor well and
cell cup for at least 10 seconds.
