WARNING
Internal electrolyte fill solution may cause skin or eye irritation.
Wear personal protection equipment (PPE).
Avoid contact with skin and eyes.
1. Shake the sensor in a downward motion to remove any air bubbles
that may be present inside the tip of the pH glass.
2. Do not install the sensor on the horizontal. The sensor must be 10
degrees off the horizontal to ensure accuracy.
3. Do not install the sensor upside down.
4. Air bubbles may become trapped in the sensor end between the
glass bulb and the sensor body. This problem is most commonly
encountered in areas of low flow or during calibration. Shake the
probe while immersed in solution to remove bubbles. To avoid this
problem, order the sensor with the slotted tip (option -41).
In most cases, you can simply install the pH sensor as shipped and obtain
readings with an accuracy of ±0.6 pH. To obtain greater accuracy or to verify
proper operation, calibrate the sensor as a loop with its compatible
transmitter.
1.2.1 Flow through and insertion mounting
Rosemount 396P and 396PVP Sensors have a 1-in. (25.4 mm) male national
pipe thread (MNPT) process connection at the front of the sensor for
mounting into a 1½-in. (38.1 mm) tee or the process pipes.

1.2.2 Submersion mounting
Rosemount 396P and 396PVP sensors also have a 1-in. (25.4 mm) male
national pipe thread (MNPT) process connection at the back of the sensor.
Using a standard 1-in. (25.4 mm) union, you can mount the sensor to a 1-in.
(25.4 mm) schedule 80 CPVC or PVDF standpipe.
Tapered pipe threads in plastic tend to loosen after installation. Therefore,
Emerson recommends using PTFE tape on the threads and checking the
tightness of the connection frequently to assure that no loosening has
occurred. To prevent rain water or condensation from running into the
sensor, Emerson recommends using a weatherproof junction box. Run the
sensor cable through a protective conduit for isolation from electrical
interference or physical abuse from the process. Install the sensor within 80
degrees of vertical, with the electrode facing down. Do not run the sensor's
cable with power or control wiring.

2 Wire
2.1 General wiring guidelines
Figures in Wiring diagrams provide guidelines for wiring the Rosemount
396P sensor to various transmitters.
To determine which wiring diagram to use, locate the model number of the
sensor to be installed.
If you need to extend the cable, use a high quality eleven conductor doubleshielded instrument cable (part number 9200273) available from Emerson.
Note
If the cable is too long, loop up the excess cable. If you need to shorten the
cable, cut and terminate each conductor neatly and make sure that the
overall (outermost) drain wire is not shorted out with either of the two inner
drain wires (shields).
Run signal cable in a dedicated conduit (preferably an earth grounded
metallic conduit) and keep it away from AC power lines. For your
convenience, Emerson has furnished a wire nut kit (in a plastic bag wrapped
around the cable).
CAUTION
For maximum electromagnetic interference/radio frequency interference
(EMI/RFI) protection when wiring from the sensor to the junction box,
connect the outer braid of the sensor to the outer braided shield of the
extension cable. Terminate the outer braid of the extension cable to the
instrument at earth ground or use an appropriate metal cable gland fitting
to provide a secure connection to the instrument cable.
2.2 Wiring diagrams
The Rosemount 396P has an optional built-in preamplifier and comes with a
shielded cable.
WARNING
Serious injury may result.
Do not connect sensor cable to power lines.
Quick Start Guide 17
Quick Start Guide November 2020
CAUTION
Handle the cable carefully and keep it dry and free of corrosive chemicals
at all times.
Take extreme care to prevent it from being twisted, damaged, or
scraped by rough, sharp edges or surfaces.
Note
Remove electrical tape or shrink sleeve away from gray reference wire
before connecting wire to terminal.

3 Start up and calibrate
3.1 Calibrate Rosemount 396P and 396PVP pH sensors
3.1.1 Prepare sensor
Procedure
1. Shake down the sensor to remove any air bubbles that may be
present at the tip of the pH glass bulb.
2. To obtain greater accuracy or to verify proper operation, calibrate
the sensor as a loop with its compatible transmitter.
3.1.2 Calibrate pH
1. Establish a temporary connection between the sensor and the
transmitter.
2. Perform a buffer calibration.
3. Consult the appropriate pH/ORP transmitter Reference Manual for
specific calibration and standardization procedures, or see Calibrate
with two buffer solutions for the recommended two-point buffer
calibration procedure.
Calibrate with two buffer solutions
Prerequisites
Select two stable buffer solutions, preferably pH 4.0 and 7.0. (You can use
pH buffers other than pH 4.0 and pH 7.0 as long as the pH values are at least
two pH units apart).
Note
A pH 7 buffer solution reads an mV value of approximately zero, and pH
buffers read approximately ±59.1 mV for each pH unit above or below pH 7.
Check the pH buffer manufacturer specifications for millivolt values at
various temperatures, as it may affect the actual value of the buffer solution
mV/pH value.
Procedure
1. Immerse the sensor in the first buffer solution. Allow the sensor to
adjust to the buffer temperature (to avoid errors due to temperature
differences between the buffer solution and sensor temperature) and
wait for readings to stabilize.
The transmitter can now acknowledge the value of the buffer.
2. Once the first buffer has been acknowledged by the transmitter,
rinse the buffer solution off the sensor with distilled or deionized
water.
Quick Start Guide 37
Quick Start Guide November 2020
3. Repeat Step 1 and Step 2 using the second buffer solution.
Once the transmitter has acknowledged both buffer solutions, a sensor
slope (mV/pH) is established (the slope value can be found within the
transmitter). The slope value should read about 59.1 mV/pH for a new
sensor and will decrease over time to approximately 47-49 mV/pH.
Postrequisites
Once the slope reads below the 47-49 mV/pH range, install a new sensor to
maintain accurate readings.
Standardize pH sensor
For maximum accuracy, you can standardize the sensor in-line or with a
process grab sample after performing a buffer calibration and conditioning
the sensor to the process. Standardization accounts for the sensor junction
potential and other interferences. Standardization does not change the
sensor's slope, but simply adjusts the transmitter's reading to match that of
a known process pH.
Procedure
1. While obtaining a process solution sample, record the pH value that
is shown on the transmitter display.
Emerson recommends taking the sample close to the sensor.
2. Measure and record the pH of the process solution sample with
another temperature compensated, calibrated pH instrument.
For best results, perform standardization at the process temperature.
3. Adjust the transmitter to the standardized value.
3.2
Calibrate Rosemount 396P and 396PVP oxidation reduction potential (ORP) sensors
Most industrial applications have a number of ORP reactions occuring in
sequence or simultaneously. Reagents can oxidize or reduce several
components. Theoretically, the ORP potential is absolute, because it is the
result of the oxidation/reduction equilibrium. However, the actual measured
potential is dependent on many factors, including the condition of the
surface of the ORP platinum electrode. Therefore, allow the sensor one to
two hours to become conditioned to the stream when it is first set up or
after cleaning it.
Procedure
1. Make a temporary electrical connection between the sensor and the
instrument.
2. Obtain an ORP standard solution (PN R508-8OZ) or make one by
adding a few crystals of quinhydrone to either pH 4 or pH 7 buffer.
38 Emerson.com/Rosemount
November 2020 Quick Start Guide
Quinhydrone is only slightly soluble; therefore, use only a few
crystals.
3. Immerse the sensor in the standard solution. Allow one to two
minutes for the ORP sensor to stabilize.
4. Adjust the standardized control of the transmitter to the solution
value shown in Table 3-1.
The resulting potentials, measured with a clean platinum electrode
and saturated KCl/AgCL reference electrode, should be within ±20
millivolts of the value shown in Table 3-1. Note solution temperature
to ensure accurate interpretation of results. The ORP value of
saturated quinhydrone solution is not stable over long periods of
time. Therefore, make these standards fresh each time they are used.

268 264 260 94 87 80
5. Remove the sensor from the buffer, rinse, and install in the process.
Quick Start Guide 39
Quick Start Guide November 2020
4 Maintenance
4.1 General maintainence information
The sensors require mimimal maintenance.
Keep the sensor clean and free of debris or sediment at all times. The nature
of the solution measured determines the frequency of cleaning. To clean,
wipe with a soft cloth or brush with a brush. Remove the sensor from the
process periodically and check it in buffer solutions.
WARNING
Before removing the sensor, be absolutely certain that the process pressure
is reduced to 0 psig and the process temperature is lowered to a safe level.
4.2 Automatic temperature compensator
The temperature compensator element is a temperature sensitive resistor
and can be checked with an ohmeter. Resistance increases with
temperature.
PT-100 reads 110 ohms. Resistance varies with temperature and can be
determined according to Table 4-2 or the following formula:
RT = RO [1 + R1(T-20)]
Where RT = Resistance and T = Temperature in °C
Refer to Table 4-1 for RO and R1 values.

4.3 Clean electrode
If the electrode is coated or dirty, clean as follows:
Procedure
1. Remove the sensor from process.
2. Wipe the glass bulb with a soft, clean, lint free cloth or tissue. If this
does not remove the dirt or coating, go to Step 3.
Detergents clean oil and grease; acids remove scale.
3. Wash the glass bulb in a mild detergent solution. If this does not
clean the glass bulb, go to Step 4.
4.
WARNING
Corrosive substance
The solution used during the following step is an acid.
Handle with care.
Follow the directions of the acid manufacturer.
Wear the proper protective equipment.
Do not let the solution come in contact with skin or clothing.
If contact with skin is made, immediately rinse with clean water.
Wash the bulb in a dilute five percent hydrochloric acid solution and
rinse with clean water.
Soaking the sensor overnight in the acid solution can improve
cleaning action.
Quick Start Guide 41
Quick Start Guide November 2020
Note
You may get erroneous pH results immediately after acid soak due to
reference junction potential buildup. Replace the sensor if cleaning
does not restore sensor operation.
4.4 Check platinum electrode
Check the platinum electrode as follows. There are two types of standard
solutions which may be used to check the oxidation reduction potential
(ORP) electrode/transmitter system.
Type 1: One type of commonly used ORP standard solution is the saturated
quinhydrone solution (PN R508-8OZ). Refer to Calibrate Rosemount 396P
and 396PVP oxidation reduction potential (ORP) sensors.
WARNING
The solution used during the following check is an acid.
Handle the solution with care.
Follow the manufacturer's directions.
Wear the proper protective equipment.
If contact with skin or clothing is made, immediately rinse with plenty of
clean water.
Type 2: A second ORP standard solution can be prepared from the following
recipe:
Procedure
1. Dissolve 39.2 grams of reagent grade ferrous ammonium sulfate,
Fe(NH4)2(SO4)2 ● 6H2O and 48.2 grams of reagent grade ferric
ammonium sulfate, FeNH4(SO4)2 ● 12 H2O in approximately 23.7 oz.
(700 ml) of water.
Distilled water is preferred, but tap water is acceptable.
2. Slowly and carefully add 1.9 oz. (56.2 ml) of concentrated sulfuric
acid.
3. Add sufficient water to bring the total solution volume up to 33.8 oz.
(1000 ml).
This standard ORP solution, although not as simple to prepare as the
quinhydrone recipe, is much more stable and will maintain its millivolt value
for approximately one year when stored in glass containers. This solution
(ferric/ferrous ammonium sulfate) produces a nominal ORP of 476 +20 mV
at 77 °F (25 ºC) when used with a saturated KCL/AgCl reference electrode
and platinum measuring electrode. Expect some tolerance in mV values due
to the rather large liquid reference junction potentials that can arise when
42 Emerson.com/Rosemount
November 2020 Quick Start Guide
measuring this strongly acidic and concentrated solution. However, if you
keep measuring electrodes clean and in good operating condition, you can
carry out consistently repeatable calibrations using this standard solution.
4.5 Clean platinum electrode
To restore the electrode to normal operation, clean the platinum electrode
with baking soda. Polish it by rubbing it with a damp paper towel and baking
soda until it appears bright and shiny.

Specific Conditions for Safe Use (X):
1. All pH/ORP sensor models with a plastic enclosure or exposed plastic
parts may provide an electrostatic ignition hazard and must only be
cleaned with a damp cloth to avoid the danger of ignition due to
build-up of electrostatic charge.
2. All pH/ORP sensor models with a metallic enclosure may provide a
risk of ignition by impact or friction. Care should be taken during
installation to protect the sensor from the risk.
3. External connections to the sensor must be suitably terminated and
provide a degree of protection of at least IP20.
4. All pH/ORP sensor models are intended to be in contact with the
process fluid and may not meet the 500V r.m.s. test to earth. This
must be taken into consideration at installation.
