1Safety Symbols
Warning!
Failure to observe the instructions can result in serious injury and damage to property!
Important notice!
Non-observance can result in serious damage to the equipment or performance restriction!
2Safety Precautions
Danger to life, risk of injury and damage to material or property.
Read the Operating Instructions carefully before initial operation.
Observe general safety precautions as well as those included in various sections of these Operating
Instructions.
Hazard risks:
-non-observance of the Operating and Safety Instructions
-modifications to the device by the customer
-handling the device outside the specified operating conditions
-handling the transducers outside the specified operating conditions
-use of unsuitable power supplies and peripheral devices
-improper use of the device
Prevention of voltage hazards:
-use only the dedicated adapter plug for the mains supply
-make sure that the PC is correctly connected to the mains (earthed safety socket, earthing) when
using a USB connection
-when connecting analog outputs or inputs to peripheral devices make sure that these are correctly
connected to the mains (earthed safety socket, earthing)
Danger when installing the sensors in pressurized pipelines:
-sensors for use in pressurized pipelines are to be inserted or retracted only in depressurized conditions;
non-observance may result in serious injuries to personnel
-when installing or removing under pressure, the appropriate protective equipment must be used,
e.g. ball valve and probe guide pieces with chain guard or spindle probe guide pieces
