6.1 Electrical mounting
DANGER!
Danger to life caused by electric current
Upon contact with live parts, there is a direct danger to life.
▶
The instrument may only be installed and mounted by skilled personnel.
▶
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!
▶
Only use the power supply unit from WIKA supplied with the instrument!
6.2 Using the instrument with thermometers
WARNING!
Physical injuries and damage to property and the environment caused by hazardous media
Upon contact with hazardous media (e.g. oxygen, acetylene, flammable or toxic substances), harmful media (e.g.
corrosive, toxic, carcinogenic, radioactive), and also with refrigeration plants and compressors, there is a danger
of physical injuries and damage to property and the environment.
Should a failure occur, aggressive media with extremely high temperature and under high pressure or vacuum
may be present at the instrument.
▶
For these media, in addition to all standard regulations, the appropriate existing codes or regulations must also
be followed.
▶
Wear the requisite protective equipment.
Prior to commissioning, check the CTR3000 multi-functional precision thermometer as well as the model CTP5000/CTP9000
temperature probes, when ordered, for integrity.

6.3.2 Warm up time
It is recommended that the CTR3000 be warmed up before use to stabilize the environmentally controlled components. This
will ensure the best performance to the specifications.
We recommend a warm up time of 1 hour for full accuracy specifications.
The internal cold junction compensation needs up to 2 hours for performing best.
