Turning unit off:
To turn the unit off, press the standby button. The temperature, speed and time displays will be blank,

Operating tips
• Opening the lid on the Incubating Orbital Shaker will cause the unit to pause shaking and/or
heating. Close the lid and the unit will resume shaking and/or heating at current settings.
• Centering your sample and even weight distribution on the tray helps with balance and stability.
• When possible, samples should be covered to prevent excess condensation inside the incubation
chamber. Should condensation occur, the use of a desiccant is recommended.
• As a safety feature, a built-in program will shut power off to the motor if the tray is prevented from
rotating, or the unit is overloaded beyond its recommended weight capacity.
• The shaker will automatically restart after a power interruption. Built-in memory maintains the last
used temperature, speed and time settings during a power interruption.

2.2 Load Sensing Function

The Incubating Orbital Shaker is equipped with a load sensing function that can be activated by the user.
This function provides protection against improper positioning of load and maximum load being exceeded.
When activated, the unit will automatically sense improper load conditions and slow to a safe running speed,
then display that speed followed by an E04 error message on the speed display. The unit will also beep
three (3) times every 60 seconds until the error is reset by pressing the speed on/off button.
To activate the load sensing function use the following steps:
1 Place the unit in standby mode.
2 Press and hold the speed on/off button and then press and release the standby button. The unit will
beep two (2) times, confirming the function is enabled.
3 To restore normal operation, remove AC power to the unit for ten (10) seconds and then restore.
