12 Troubleshooting
Risk of explosion!
Risk of serious injury from electricity and escaping gases!
• Troubleshooting may only be carried out by instructed persons!
• Before carrying out maintenance work on the combustion calorimeter and
whenever necessary, bring the the linked system components to a standstill
as well!
• Switch off the main switch and disconnect the device from the voltage
supply, if necessary, and take steps to prevent the main switch from being
switched on again and the voltage supply from being reconnected!
• Only skilled electricians are permitted to work on the electrical equipment of
the combustion calorimeter!
• Parts of the combustion calorimeter with the adjacent symbol may still carry
voltage even when the main switch is switched off!
• If required, separate the combustion calorimeter from the voltage supply!
Troubleshooting is broken down into the following categories:
• Unstable measured value
• Drift of measured value
• Incorrect ignition behavior
