Ensure that the complete operating instructions are always available in excellent condi-
tion at the calibrator / micro calibration bath installation site.
Thermal fuse
For protection purposes, the calibrator / micro calibration bath is equipped with an auto-
nomous thermal fuse, which interrupts the power supply to the heater if the temperature
exceeds a certain value inside the housing. Once the metal bock / liquid bath has cooled
down, the calibrator / micro calibration bath has to be returned to SIKA for inspection.
The calibrator / micro calibration bath has been designed as a measurement and control
instrument. If the calibrator / micro calibration bath is used for purposes not expressly
specified in these operating instructions, additional safety measures have to be taken.
The calibrator / micro calibration bath should
NOT
be used in
explosive atmospheres
without appropriate protection (flammable or explosive atmospheres).
Do not remove or obliterate nameplates or other markings on the device, as otherwise the
warranty is rendered null and void.
Special safety instructions:
(Further) Warnings that are specifically relevant to individual operating procedures or activi-
ties can be found at the beginning of the relevant sections of this operating manual.
2.1 Safety instructions for the application of calibration liquids
Calibration liquid water:
Only use distilled water, otherwise excessive limescale and soiling will build up in the ca-
librator tank.
Calibration liquid silicone oil:
Only use distilled water, otherwise excessive limescale and soiling will build up in the cali-
brator tank.
Always read the safety data sheet supplied with the silicone oil before using it.
Always ensure adequate ventilation when working with silicone oil, since hazardous sub-
stances can be released.
Prevent silicone oil from coming into contact with your eyes.
Since silicone oil is hygroscopic, always use the transport cover to close the calibration
bath after use.
IMPORTANT NOTICE!
The transport cover is equipped with a safety valve, which is activated once the pressure
reaches approx. 2.5 bar. This can result in hot steam being released.
Always unscrew the transport cover before putting the micro calibration bath into ser-
vice, in order to avoid excessive pressure.
Wait until the micro calibration bath has cooled down before screwing on the transport
cover.
