3.3 Overview
The calibrator consists of a robust, grey-blue painted steel
case, with a carrying handle on top.
The rear part of the case includes a metal block with seven
bores for the test items, accessible from the top.
The metal block incorporates the heating or cooling elements
and the temperature sensor for determining the reference
temperature.
The metal block is thermally insulated.
The front part of the case 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
4-digit, high-contrast LED display for the reference and set
temperature.
