A)

  At 25 °C

B)

  The working range may be reduced by unfavourable environmental conditions (e.g. direct sunlight).

C)

  Along the axes

D)

  Only non-conductive deposits occur, whereby occasional temporary conductivity caused by condensation is expected.

The serial number (16) on the type plate is used to clearly identify your measuring tool.
