6. Indicator check / 7. Indicator correction

6. Indicator check

The check of the indicator should only be carried out in comparison with a more
accurate instrument or, if possible, with a calibrated instrument. The tempera-
ture during the check must remain constant. Fluctuating temperatures may
lead to reading errors caused by the different response times of the probes.
GB
For thermometers without protective sleeves, a minimum waiting time of
10 minutes, for temperature equalisation, should be observed, provided the
appropriate immersion length is adhered to.
Attention: Only gaseous pressure-free media are admissible!
For thermometers with protective sleeves, a minimum waiting time of at least
15 minutes, for temperature equalisation, should be observed, provided the
appropriate immersion length is adhered to.
Admissible working pressure at the pocket: max. 6 bar

7. Indicator correction

Any interference with or modification to the instrument will invali-
date the warranty!
■
The indicator correction built into the bottom of stem should only be operat-
ed using a screwdriver, and only if the thermometer has been damaged due
to improper handling, severe shocks, during transport, etc.
■
When correcting an indication error using the adjustment mechanism, a
calibrated thermometer must be used for comparison. Subsequently, the
thermometer must be checked at several temperature points.
