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 instruc-
tions not be observed, there is a risk of serious or fatal injury.
2. Safety
WARNING!
Before installation, commissioning and operation, ensure that the
appropriate loop calibrator been selected in terms of measuring range,
design and specic measuring conditions.
Non-observance can result in serious injury and/or damage to equip-
ment.
Further important safety instructions can be found in the individual
chapters of these operating instructions.

2. Safety
2.1 Intended use
The precision loop calibrator CEP1000 is designed for high-accuracy measuring and
simulation of current and voltage.
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. Should the instrument be improperly handled or operated outside of its
technical specications, it has 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 the instrument malfunctioning. 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.
Special operating conditions require further appropriate knowledge, e.g. of aggressive
media.

2. Safety
2.3 Special hazards
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.
WARNING!
Protection from electrostatic discharge (ESD) required.
The proper use of grounded work surfaces and personal wrist straps is
required when working with exposed circuitry (printed circuit boards),
in order to prevent static discharge from damaging sensitive electronic
components.
To ensure safe working on the instrument, the operating company must
ensure that the operating personnel are regularly instructed in all topics
regarding work safety, rst aid and environmental protection and knows
the operating instructions and, in particular, the safety instructions
contained therein.
DANGER!
Danger of death caused by electric current!
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!

4. Design and function
4.1 Short description / Description
The CEP1000 is a loop calibrator operating in the range of 4 ... 20 mA designed for
both troubleshooting and calibration of circuits without separate power supply.Very
high accuracy and diverse special functions make the instrument to a user-friendly and
highly exible calibration instrument.
The CEP1000 can be used as current reference standard for up to 24 mA, it can also be
used to simulate a 2-wire connection or to perform measurements in circuits with up to
24 mA without separate power supply.
By means of the calibrator it is possible to measure process signal voltages of up to 28 V
direct current with an accuracy of 0.015 % of the measurement value.

Using the digital knob user interface as well as the decade output control the user
can set both large and incremental changes of the output signal conveniently. Multiple
unique functions such as the automatic step/ramp function allow easy application of the
CEP1000.
Besides the CEP1000 can supply a 2-wire transmitters with voltage and at the same
time measure the emerging current. All measurements are displayed in mA as well as in
percent of the measuring range.
