Explanation of symbols
WARNING!
... indicates a potentially dangerous situation that can result in serious
injury or death, if not avoided.
CAUTION!
... indicates a potentially dangerous situation that can result in light
injuries or damage to equipment or the environment, if not avoided.
Information
... points out useful tips, recommendations and information for ecient
and trouble-free operation.
DANGER!
... identies hazards caused by electric power. Should the safety
instructions not be observed, there is a risk of serious or fatal injury.
2. Safety
WARNING!
Before installation, commissioning and operation, ensure that the
appropriate hand-held temperature calibrator has been selected in
terms of measuring range, design and specic measuring conditions.
Non-observance can result in serious injury and/or damage to the
equipment.
Further important safety instructions can be found in the individual
chapters of these operating instructions.

2. Safety
2.1 Intended use
This hand-held temperature calibrator model CEP3000 is used for high accuracy
measurement and simulation of temperatures.
The instrument has been designed and built solely for the intended use described here,
and may only be used accordingly.
The technical specications contained in these operating instructions must be
observed. Improper handling or operation of the instrument outside of its techni-
cal specications requires the instrument to be taken out of service immediately and
inspected by an authorised WIKA service engineer.
Handle electronic precision measuring instruments with the required care (protect from
humidity, impacts, strong magnetic elds, static electricity and extreme temperatures,
do not insert any objects into the instrument or its openings). Plugs and sockets must be
protected from contamination.
If the instrument is transported from a cold into a warm environment, the formation of
condensation may result in instrument malfunction. Before putting it back into operation,
wait for the instrument temperature and the room temperature to equalise.
The manufacturer shall not be liable for claims of any type based on operation contrary
to the intended use.
2.2 Personnel qualication
WARNING!
Risk of injury should qualication be insucient!
Improper handling can result in considerable injury and damage to
equipment.
■
The activities described in these operating instructions may only
be carried out by skilled personnel who have the qualications
described below.
■
Keep unqualied personnel away from hazardous areas.
Skilled personnel
Skilled personnel are understood to be personnel who, based on their technical training,
knowledge of measurement and control technology and on their experience and knowl-
edge of country-specic regulations, current standards and directives, are capable of
carrying out the work described and independently recognising potential hazards.

2. Safety
Special operating conditions require further appropriate knowledge, e.g. of aggressive
media.
2.3 Special hazards
WARNING!
■
Observe the working conditions in accordance with chapter 3
"Specications".
■
Operate the temperature measuring instrument within the tempera-
ture ranges.
■
Do not use the hand-held temperature calibrator in damaged condi-
tion. Before using the calibrator, check the housing and check the
calibrator for missing plastic parts and cracks. Pay particular atten-
tion to the insulation surrounding the connectors.
■
Select the proper function and correct measuring range.
■
Before commissioning the calibrator, close the battery compartment
and lock it.
■
Before opening the battery compartment, disconnect the measuring
lines of the hand-held temperature calibrator.
■
Check the measuring lines for signs of damaged insulation or metal
parts with natural nish.
■
When using probes, keep the ngers away from the probe contacts.
Hold the probes behind the nger protection at the measuring lines.
■
Do not use the hand-held temperature calibrator in case of malfunc-
tion. The instrument protection might be compromised. In cases of
doubt, have the hand-held temperature calibrator repaired.
■
Do not operate the hand-held temperature calibrator in ambiences
with explosive gases, vapours or dusts.
■
Disconnect the measuring lines prior to switching to another
measurement or before using as a simulator.
■
Incorrect measurements can lead to an electric shock or injuries. To
avoid this, replace the batteries immediately when a used battery is
indicated.
■
In order to guarantee a trouble-free operation, the hand-held
temperature calibrator should only be battery driven or driven by
rechargeable batteries.
WARNING!
In order to avoid damages at the temperature calibrator or the devices
to be controlled, use the correct connection terminals, functions and
measuring ranges for the measurement or the simulation.

2. Safety
WARNING!
For hazardous media such as oxygen, acetylene, ammable or toxic
gases or liquids, and refrigeration plants, compressors, etc., in addition
to all standard regulations, the appropriate existing codes or regula-
tions must also be followed.
DANGER!
Danger of death caused by electric current
Upon contact with live parts, there is a direct danger of death.
Operation using a defective power supply unit (e.g. short circuit from
the mains voltage to the output voltage) can result in life-threatening
voltages at the instrument!
WARNING!
Residual media on the dismounted hand-held temperature calibrator
can result in a risk to persons, the environment and the equipment.
Take sucient precautionary measures.
Do not use this instrument in safety or Emergency Stop devices. Incor-
rect use of the instrument can result in injury.
