4 | PTC Temperature Calibrators–English
2.3 Special Safety Instructions
•
Thermal protection fuse.
a. The calibrator is equipped with a thermal protection fuse that works independently. If
there is an over-temperature inside the housing, the power supply to the heating
system is cut off. The thermal protection fuse is non-resettable. The calibrator cannot
be used anymore.
b. After the calibrator has cooled, return the calibrator to Druck.
•
Risk of injury from hazardous gases.
a. When liquids are heated, evaporation can result in dangerous gases being released.
•
The calibrator may not be used in a potentially explosive atmosphere.
a. Remove all the easily flammable media from the vicinity of the calibrator.
b. Ensure that the calibrator cannot come in contact with easily flammable or explosive
media.
•
Operate the calibrator only in the temperature range permissible for the DUT.
•
Ensure that the DUT is held securely in the calibrator.
a. Use only suitable inserts.
b. When doing so, also ensure that the structural safety of the calibrator is retained.
•
Expert mode.
a. When selecting the function, DUT and testing tasks, you can switch into the expert
mode for administration and configuration. The settings that are made in this mode
require detailed knowledge of the calibration and method of working of calibrators.
b. If the settings are incorrect, the calibrator may be damaged.
2.4 Calibration Liquid Safety Instructions
Before using calibration liquids, read the entire safety data sheet thoroughly. Pay particular
attention to the information on the physical and chemical properties.
Only use calibration liquids that are suitable for the required temperature range and which are not
flammable.
INFORMATION
The transport cover has a pressure relief safety valve. The
valve opens when the micro bath pressures exceeds ~1.5 bar. This can result in
hot vapor being released.
Remove the transport cover before using the micro bath.
Wait until the micro bath has cooled down before screwing on the transport
cover.
