WIKA operating instructions bimetal thermometers for HVAC6

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 temperature

during the check must remain constant. Fluctuating temperatures may lead to

reading errors caused by the dierent response times of the probes.

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 modication to the instrument will invalidate

the warranty!

■

The indicator correction built into the bottom of stem should only be operated

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.

1) not for clip-on thermometer model A46.11 and edgewise panel design
