Remarks
• The heating system works independently from the ultrasound.
• The last selected temperature is not saved.
When the ultrasonic bath is switched on again (ON/OFF), the target temperature
defaults to "0".
• The heating will automatically turn on every time that the bath temperature drops
below the set temperature.
• The temperature scale display is accurate to ±2.5°C.
Avoid retardation of boiling
If a temperature is set, the ultrasonic bath attempts to reach the selected temperature
immediately.
When heating (without the ultrasound switched on), the ultrasound is automatically
switched on for 3 seconds per minute to agitate the liquid and consequently avoid
retardation of boiling.
- This function is always active at temperatures > 60°C and cannot be switched
off!
- The function can be switched off for temperatures < 60°C. It must be reactivated
every time the unit is switched on. Activating the function:
By pressing the temperature setting button when you switch the unit on (Button
ON/OFF).
