4. Design and function
4.1 Description
The calibrator or micro calibration bath is a portable unit, for
service functions and also for industrial and laboratory tasks.
The temperature calibrators and micro calibration baths
from WIKA are provided for the calibration of thermometers,
temperature switches/thermostats, resistance thermometers
and thermocouples. The operational safety of the delivered
instruments is only assured if the equipment is employed for
its intended use (verification of temperature sensors). The
given limit values should never be exceeded (see chapter
3 “Specifications”).
The appropriate instrument should be selected depending on
the application; it should be connected correctly, tests carried
out and all components serviced.
The instrument is manufactured in different versions. The
individual version for any single unit can be found on the
nameplate on the calibrator/micro calibration bath.
4.2 Scope of delivery
The calibrators/micro calibration baths are delivered in
special protective packaging. The packaging must be set
aside so that the calibrator or the micro calibration bath can
be sent safely back to the manufacturer for recalibration or
repair.

The calibrator and micro calibration bath consist of a robust,
grey-blue-painted steel enclosure, with a carrying handle on
top.
The rear part of the enclosure includes a metal block or
liquid bath with an opening for the test item, accessible from
the top.
The metal block/liquid bath incorporate the heating or cooling
elements and the temperature sensor for determining the
reference temperature.
The metal block and the liquid bath are thermally insulated.
The front part contains the complete electronic unit for
controlling the reference temperature.
Solid state relays (SSR) are used to control the heating and
cooling elements.
On the front panel is the controller, which is fitted with a
7-segment LED (2 rows of 4 digits) for the reference and set
temperature.
The micro calibration bath has an additional knob for control-
ling the stirring speed.
