Table 41: Summarizing Maintenance Table
Depending on usage. Perform once a
month if system is not used often
Only if system is not being used
regularly.
Requires a calibration kit. Some
study protocols may require
Thermode calibration more often

22.2.1 Visual Check
The visual check is important to ensure that all system components are intact and properly
connected before using the system.
The Visual check is required in order to make sure that there is no physical
damage to system components, particularly to the Thermodes.
1. Check all accessories and Thermodes visually.
1.1. Check that the accessory connectors are intact.
1.2. Check that the all the accessories’ bodies are intact.
1.3. Check that there is no visible damage to the Thermode heads. Check especially that
the Kapton® cover of the CHEP Thermode is intact and not peeled.
