6.9 Cooling down the metal block

WARNING!
Risk of burns!
High temperatures at the metal block or at the
temperature probe can lead to acute burns.
▶ Before transporting or touching the metal
block and/or calibration instruments, make
sure that they have cooled down sufficiently.
▶
In order that the calibration instruments can
be brought quickly from a higher to a lower
temperature, set the set temperature to a
lower temperature (e.g. room temperature).
▶ In order to cool down the metal block, set the
set temperature to a low temperature, e.g.
room temperature.
1. With the [▲] or [▼] button, enter the room temperature.
2. Confirm the entry with the [E] button.
The installed fan gently and automatically switches to a
higher speed thus providing more cooling air.
After switching off or removing the mains
connection, no cooling air will be provided by
the built-in ventilator. If the voltage supply is
interrupted during the cooling process, sufficient
thermal decoupling is still guaranteed between
the metal block and the case.
