Safety Precautions
This section provides precautions to enable you to use the product safely and correctly and to
prevent injury and damage. The terms of DANGER, WARNING, and CAUTION indicate the
degree of imminency and hazardous situation. Read the precautions carefully as it contains
important safety messages.
WARNING
When any load larger than the contact capacity or any induction load (e.g., a motor or a pump) is
used, be sure to connect that load via a power relay that has a rating larger than the load rating.
When the HP-200 may be subject to lightning, install a conductor rod on the output side of the HP-200
and on the side of receiving instruments.
Be sure to connect the grounding terminal (class D grounding) for safety.
Electric shock
Be sure to check that no power is supplied before starting work.
Strong acid
If dilute hydrochloric acid gets into the eye, mucous membrane may be irritated, resulting in the loss of
sight.
In handling hydrochloric acid, be sure to use protective goggles, protective gloves, and a protective
mask.
If hydrochloric acid gets into the eye, immediately rinse the eye with a large quantity of water for at
least 15 minutes and then receive medical attention. (When rinsing the eye, well open it with fingers
so that the eyeball and the eyelid can be fully cleaned.)
If hydrochloric acid adheres to your body or clothes, you may get burned. Therefore, immediately
remove the clothes and then rinse off hydrochloric acid with a large quantity of water.
CAUTION
If there is corrosive gas in the installation environment, send clean instrumentation air from the air
purge inlet on the HP-200.
When the HP-200 is OFF, the C-NC contact is short-circuited. Therefore, be careful about the
connection of any load.
Since operation of the HP-200 at any voltage outside the rated range can cause a fault, check the
power supply voltage. Also check that the voltage fluctuation range of the power source falls within
the range of rated voltage ±10%.
The electrode is a glass product, which is broken if it is exposed to an impact, strong force, or the like.
In handling the electrode, therefore, exercise sufficient care.

Product Handling Information

Therefore, exercise the following precautions:
zDo not press any operation key with the tip of your nail or any pointed thing.
zDo not use organic solvent or the like.
zDo not immerse the HP-200 in dilute hydrochloric acid for long hours.

zThe ambient temperature shall be between -20°C and 55°C both inclusive.
zHot air in the location shall be minimal.
zThe HP-200 shall not be exposed to direct sunlight.
zThe HP-200 shall not be exposed to direct high radiation heat.
zThe ambient relative humidity shall be 90% maximum.
zThe HP-200 shall not be exposed to splashed water or chemical agent
zThe mechanical vibration in the location shall be minimal.
zMaintenance and wire connections shall be possible in the location.

Installing the electrode
The electrode can be installed by either of the following two methods:
zSet up the electrode with a holder and then directly immerse the holder in the solution
under measurement (immersion type holder).
zSet up the electrode with a holder and then directly insert the holder into the piping line
(distribution type holder).
For detailed handling of each holder type, refer to the instruction manual that comes with the
product.
QFor immersion type holder
1. Ensure that the electrode tip is always immersed in the solution under
measurement even if the solution level fluctuates.
2. Ensure that the level of the internal solution (KCl) in the holder is always higher
than the level of the solution under measurement.
Note
If the level of the internal solution (KCl) in the holder decreases, be sure to add the internal solution.
3. Slightly turn the cap at the top of the holder. The filling inlet will be slightly opened
so that large pressure is applied to the inside of the holder.
4. The maximum flow rate is 2 m/s. Even if the flow rate is within this limit, the folder
may be deformed. Therefore, take the following measures to prevent a decrease in
the flow rate.
QFor distribution type holder
1. Be sure to provide a bypass line on the piping line.
Note
Unless there is a bypass line, the HP-200 must be stopped when the maintenance or replacement of
the electrode is carried out.
2. Use the distribution type holder with its output side open to atmospheric air.
3. Before checking the electrode, close the valve located upstream from the holder.
The solution in the holder may flow back.
Holder cap
KCl filling inlet
Install a pipe of 50 to 100
A that has a introducing
hole at its end and then
insert the holder into that
pipe.
When a partition plate
can be installed, e.g., on
both sides of a street
gutter, install those plates
upstream for the benefit
of dust removal.

Installation
12
4. An excessively high flow rate may cause fluctuations in the reading. An
excessively low flow rate results in response delay. Control the flow rate in
accordance with the measurement conditions.
5. For any solution under measurement that has large SS content, install a strainer on
the incoming side.
Procedures for connections
QOpening the cover for the HP-200
1. Remove two screw caps located on the upper part of the front of the HP-200.
Carefully store the removed caps.
2. Open the front cover.
3. Loosen four screws located on the front of the HP-200. Check that the screws are
floated by springs.
4. Open the front case for the HP-200.
QDiagram of connection terminals
Note
zThe screws on the front case and the terminal block are structurally prevented from coming off.
To connect a terminal, turn the screw counterclockwise until the spring is floated.
zTo open the case immediate after it has rained, previously wipe off droplets on the case.
