53 WIKA Operating Instructions CTD9300 Rev. 1
Check and ensure the following:
„ The calibrator must be complete. An adapting sleeve with an
inside diameter of 6.5 mm, appropriate for probes with a
diameter of 6 mm, a sleeve removal tool, a power cable, an
RS 232 interface cable and operating instructions are standard
accessories.
„
The probe and the adapting sleeve as well as the bore of the
block must match exactly to keep the thermal contact resistance
as low as possible.
„
The mains voltage must match the supply voltage specified on
the type label.
„ The device must be connected to a power circuit with minimum
risk of a power failure, since it will no longer be possible to
supply cooling air in the case of a power failure.
„ All the bores of the adapting sleeve must be clean and free of
damage and foreign matters.
„
After activation via the power switch and switchover from
standby to standard operation, the fan must start when button
(B) is pressed.
Calibrators with a hot dry well always bear an imminent hazard of
burns.
Risk of burns!
Depending on the type, the dry well of a calibrator may reach
temperatures of up to 650 °C.
Let the calibrator cool after use. Only transport the calibrator after it
has cooled completely. The dry well temperature should be below
30 °C.
When touching the surface of the heating block, the adapting
sleeve or the probe, or even when approaching them, there may be
an imminent hazard of burns. Never touch these surfaces if you are
not absolutely sure that these parts are cold.
