1. General information / 2. Safety

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 ecient

and trouble-free operation.

DANGER!

... identies 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 specic 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 specications contained in these operating instructions must be

observed. Improper handling or operation of the instrument outside of its techni-

cal specications 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 qualication

WARNING!

Risk of injury should qualication be insucient!

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 qualications

described below.

■

Keep unqualied 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-specic 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

"Specications".

■

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 sucient precautionary measures.

Do not use this instrument in safety or Emergency Stop devices. Incor-

rect use of the instrument can result in injury.
