General advice
In the unlikely event that you experience any problems with your Tecal which
cannot be easily remedied, you should contact your supplier and return the
unit if necessary. Please include any details of the fault observed and
remember to return the unit in its original packing. The insert must be
removed from the unit and packed separately within the case. Techne
accept no responsibility for damage to units which are not properly packed
for shipping: if in doubt, contact your supplier.
General fault finding
HELP display
If HELP is displayed there is a problem with the internal sensing device. The
calibrator should be returned to your supplier for repair.
Over-temperature Cut-out
If the over-temperature cut-out trips it can be reset by switching the unit off,
waiting a few seconds,then switing it on again. If it repeatedly trips, please
contact your local supplier.
Cleaning your Tecal unit
Before cleaning your unit, disconnect from the power supply and allow to
cool to ambient temperature.
You can clean the case of the Tecal with a cloth dipped in water or ethanol
(methanol can also be used). No part of the case or cover should be
immersed in the solvents.
Do not use acetone or abrasive cleaners.
Before using any cleaning or decontamination method except those
recommended in this manual, the responsible body should check with
Techne that the proposed method will not damage the equipment.
Fuses
If neither the power light nor display (on the front panel) is lit, one of the two
fuses may have blown. Make sure there is no external cause (such as a
faulty plug or lead).
Fuses should only be changed by suitably qualified personnel. If the fuses
blow persistently, a serious fault is indicated and you should return the
calibrator to your supplier for repair.
Never fit a fuse rated higher than the value indicated on the unit, serious
damage or personal injury may result.
