The purpose of the 2 amp fuse is to break the circuit to prevent overloading on the
circuit due to high voltage.

The instrument configuration and parameters available to the operator depend on the
customer requirements.

Temperature Controller Replacement

Before handling the controller: wear an anti-static wrist strap or
otherwise avoid any possibility of damage to the unit by static electricity.
Refer to the detailed instructions supplied with the replacement
controller.

Ease apart the two lugs at the side; grip the instrument and withdraw it from its sleeve;
push in the replacement.
