2.3 Special hazards
WARNING!
■
Pressure sensors should only be tted or removed when the system
is free from pressure.
■
Observe the working conditions in accordance with chapter
"3. Specications".
■
Always operate the pressure indicator within its overload limits.
■
Residual media in dismounted precision hand-held pressure indica-
tors and/or their sensors, can result in a risk to persons, the environ-
ment and the equipment.
Take sucient precautionary measures.
■
Do not use this precision hand-held pressure indicator in safety or
Emergency Stop devices. Incorrect use of the precision hand-held
pressure indicator can result in injury.
■
Should a failure occur, aggressive media with extremely high temper-
ature and under high pressure or vacuum may be present at the
precision hand-held pressure indicator and the sensors.
■
Plan the wiring especially carefully when connecting to other devices.
Under certain circumstances, internal connections in third-party
devices (e.g. GND connected to the ground) can lead to impermis-
sible voltages that could compromise or even destroy the function of
the device itself or a device connected to it.
■
To ensure problem-free operation, only operate the precision hand-
held pressure indicator on battery power. Only use the mains lead for
charging the batteries of the precision hand-held pressure indicator.
■
Only use the sensor cable available from WIKA for the precision
hand-held pressure indicator. Do not connect any cable over 3 m
long to the CPH6400.
■
The measurement signal of the reference (or test sample) can be
inuenced by large electromagnetic eects and the display of the
signal may be lost completely.
■
The display screen is made from glass. If there is any possibility of
the screen breaking during operation, all personnel in the vicinity of
the instrument must wear eye protection before and during its use.
■
If the CPT6400 reference pressure sensor is used in applications
with oil as a pressure medium, make sure it is not be used with
ammable material or gases directly afterwards, since this can lead
to dangerous explosions and a risk to personnel and machinery.

2. Safety
WARNING!
Never take the Lithium-Ion battery apart nor alter it in any way. It contains
safety and protection devices which, if damaged, may cause it to gener-
ate heat, explode or ignite.
WARNING!
Never place the Lithium-Ion batteries close to res, ovens or other high
temperature locations. Never leave the Lithium-Ion batteries in direct
sunshine or use or store them inside cars in hot weather. Doing so may
cause the Lithium-Ion batteries to generate heat, explode or ignite.
Using the Lithium-Ion batteries in this manner may also result in a loss of
performance and a shortened service life.
Never t the Lithium-Ion batteries into equipment designed to be hermet-
ically sealed. In some cases hydrogen or oxygen may be discharged
from the cell, and thus damage the Lithium-Ion batteries, and lead to re
or explosion
WARNING!
The Lithium-Ion batteries must, without fail, no longer be used if, during
operation, charging or storing they give o an unusual smell, feel hot,
change colour, change shape, or appear abnormal in any other way.
Contact your reseller if any of these problems are observed.
Never put the Lithium-Ion batteries in microwave ovens, high-pressure
containers nor on induction cookers.
Should the Lithium-Ion batteries ever leak and the uid come into contact
with the eyes, do not under any circumstances rub the eyes. Rinse the
eyes thoroughly with water and seek immediate medical attention. If the
eyes are left untreated, damage to the eyes could occur.
CAUTION!
When the Lithium-Ion batteries wear out, insulate the terminals with
adhesive tape or similar materials before disposal.
