To avoid injuries or damage to property observe further
points:
Temperature dry-well calibrator
Only operate the calibrator in a defect-free, functioning
■
condition.
Faultless and safe operation of this calibrator requires
■
proper transport, professional storage, installation,
mounting and use as intended in addition to careful
operation and maintenance.
The calibrator has been designed as a controller. With
■
any operation of the calibrator not expressly provided
for in these operating instructions, additional protective
measures must be taken.
The electronic µ processor is factory configured so that all
■
technical specifications are maintained. These parameters
must not be changed, above all to prevent malfunction or
failure which could lead to damage.
WIKA operating instructions, model CTD4000
Keep clear the area around the calibrator on all sides and
■
especially behind the calibrator.
Do not put anything on the top of the calibrator.
■
Only carry out maintenance on the calibrator when it has
■
cooled down and been switched off.
Before switching off, ensure that the calibrator has
■
cooled to room temperature (CTD4000-140) or < 100 °C
(CTD4000-375/CTD4000-650).
The calibrator must only be stored in the carrying case
■
once it has cooled down.
Do not switch off the calibrator when it is operating at high
■
temperature because the protective grille and the case
may overheat.
Do not use any oil or liquids since these can lead to
■
damage of the calibrator.
Do not put any fuel containers near the calibrator.
■
Voltage supply
The mains socket must be freely accessible at all times!
■
Ensure that the female connector, when connected to the
■
voltage supply, is properly grounded.
With the following points, the temperature dry-well
■
calibrator must be disconnected by unplugging the power
cord from the mains socket.
▶
Before exchanging the fuse
▶
Before cleaning
▶ Before service/maintenance
▶ In the event of danger
Interface
Do not connect any voltage to the RS-232 input.
Fuse
Remove the fuse from the calibrator only when the power
connection has been disconnected from the mains.
Temperature switch test
Do not connect any voltage to the switch test connection.
■
Do not connect any voltage during the test of the
■
thermostats.
Any use beyond or different to the intended use is considered
as improper use.
Do not use this instrument in safety or emergency stop
devices.
