Safety Instructions:
Remove all highly combustible media from the vicinity of the
device and ensure that it cannot come into contact with easily
inflammable or explosive substances.
Make sure that the integrated fans can always deliver sufficient
cooling air. Do not impair the air supply by placing the devices
on a soft, resilient surface.
Connect the devices 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
Make sure that the adapting sleeves and probes are not
contaminated with any substances (e.g. oil) that may cause
ignition or explosion during heating.
Never remove adapting sleeves from a heated dry well since
heated adapter inserts bear a fire hazard.
Never remove probes from a heated dry well since these bear the
imminent risk of burns.
Never leave a heated device unattended.
Always let a heated device cool to below 50 °C before
disconnecting it from the mains.
Never try to repair the device yourself, always revert to the
manufacturer.
Since the housing of the calibrator is made of metal, only power
cables with ground wire may be used. Operate the calibrator
exclusively with the power cable provided. The power cable
connector is on the bottom of the calibrator, i.e. when using a
different type of cable, the calibrator may topple over.
If the calibrator is not used for an extended period of time, humidity
may penetrate into the heating element due to the material used.
After transporting or storing the calibrator in a humid environment,
the heating elements must thus be heated slowly when starting the
calibrator. During the drying process, the calibrator will not have
attained the isolation voltage required for protection class I.
The noise ramps of all dry well calibrators of the CTD 9300 series
are below 70 dbA.
