1.1 Intended use
The calibrators of the series DryTC / LiquidTC are only allowed to use for the test and calibration of temperature sensors.
The operational safety of the supplied instruments is only guaranteed if they are operated according to their intended use. Specified limit values ( § 14 "Technical data") should never be exceeded.
CAUTION! Risk of severe burns!
Prior to transport or contact with the metal block / liquid bath ensure that it has cooled down sufficiently, otherwise there is a risk of severe burns caused by the metal block / liquid bath and the test specimen.
CAUTION! Material damage!
The opening in the metal block of the calibrator is only intended to be used with adapter sleeves or insert sleeves.
Using heat transfer media (oil, thermal paste or other media) can lead to incorrect measurements and damage to the calibrator.
Never fill the calibrator opening with a heat transfer medium.
Only micro calibration baths are suitable for use with heat transfer medium.
It is the users responsibility to select the instrument which is suitable for your specific application, to connect it correctly, to carry out tests and to maintain all the components

Safety Instructions |
General safety instructions:
Always observe the following safety instructions in this operating manual.
In all work, the existing national regulations for accident prevention and safety in the workplace must be complied with. Any internal regulations of the operator must also be complied with, even if these are not mentioned in this manual.
Only use the DryTC / LiquidTC if it is in perfect condition. Damaged or faulty devices must be checked without delay and, if necessary, replaced.
Degree of protection according to EN 60529:
Ensure that the ambient conditions at the site of use does not exceed (comply with) the requirements for the stated protection rating (§ 14 "Technical data").
Correct and safe operation of the calibrator / micro calibration bath demands correct transport, storage, installation and assembly, as well as proper use and careful operation and maintenance.
The calibrator / micro calibration bath should only be used for its intended purpose. Furthermore, hazardous media should not be used and all technical specifications have to be observed.
If faults cannot be cleared, immediately shut down the calibrator / micro calibration bath and ensure that it cannot be started up accidentally.
Prior to replacing the safety fuse, always de-energize the calibrator / micro calibration bath completely by disconnecting the mains cable from the mains outlet.
Ensure that the complete operating instructions are always available in excellent condition at the calibrator / micro calibration bath installation site.
Thermal fuse:
For protection purposes, the calibrator / micro calibration bath is equipped with an autonomous 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 GE 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).
If malfunctioning of the calibrator / micro calibration bath can result in personal injuries or damage to property, the system has to be protected with additional electromechanical protective equipment.
Do not remove or obliterate nameplates or other markings on the device, as otherwise the warranty is rendered null and void.
Ventilation ports:
Located both underneath and on top, should not be blocked or restricted.
Disconnecting device:
Do not position the equipment so that it is difficult to operate the disconnecting device.

Safety Instructions |
DryTC / Liquid TC |
Device protection:
If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired
Replacing detachable mains supply cords:
It is not allowed to replace detachable mains supply cords by inadequately rated cords.
IEC mains connector:
The IEC mains connector of the power supply cord is to be treated as the disconnect device, as the front panel switch is not rated as a disconnect device.
Special safety instructions:
(Further) Warnings that are specifically relevant to individual operating procedures or activities 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 calibrator tank.
Calibration liquid silicone oil:
Only use distilled water, otherwise excessive limescale and soiling will build up in the calibrator 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 substances 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 service, in order to avoid excessive pressure.
Wait until the micro calibration bath has cooled down before screwing on the transport cover.

Using Test Specimen Fixtures |
DryTC / Liquid TC |
4 Using Test Specimen Fixtures
The temperature calibrators in the DryTC / LiquidTC series can be used with various test device fixtures, depending on the model.
Configuration as a metal block calibrator, infrared calibrator or micro calibration bath is easily performed with minimal effort.
4.1 Metal block calibrator
Insertion sleeves with one or more boreholes are used for the calibration of straight temperature sensors.
In order to achieve the best possible accuracy, the utilization of exactly fitting sleeves is necessary.
The diameter of the test specimen has to be determined precisely. The bore in the sleeve results from the addition of +0.5 mm.
Before use:
Using the sleeve changing tool, fit the appropriate insertion sleeve in the block of the calibrator.
After use:
Remove the sleeves after use with the aid of the sleeve remover, and remember to clean the sleeve and the block.
This prevents the sleeves becoming jammed in the heating block.
Sleeves and sleeve remover
4.2 Infrared calibrator
A special infrared insertion sleeve is used for contactless infrared thermometers to enable fast, easy calibration.
The hollow and specially constructed insertion sleeve is fitted with two additional boreholes - for precise monitoring of the temperature - in the rim (1 x 3.5 mm und 1 x 4.5 mm).
Before use:
The insertion sleeve is inserted into the block with the aid
of the sleeve remover. |

After use: |
|
Remove the sleeves after use with the aid of the sleeve |
