actuator heat block.
3. Wait for temperature equilibration to occur (minimum 10 minutes) and check
the Temperature Verification Cartridge reading.
4. The instrument-displayed temperature and the Temperature Verification
Cartridge temperature should both be within 36.5°C to 37.5°C. The
Temperature Verification Cartridge temperature should be within ± 0.5°C of

the problem.
