from flasks, etc., the display temperature may differ from temperatures within the
flasks themselves.
If you wish to have the temperature display (“Indicated Temperature”) match the
temperature at a given point, or match the average of a series of points within the
chamber (“Actual Temperature”), proceed as follows:
1. Let the unit equilibrate at or near the desired temperature. Record the Indicated
Temperature.
2. Record the Actual Temperature.
3. Calculate the temperature correction value: Actual Temperature – Indicated
Temperature = Temperature Correction Value.
4. Press the SELECT key until the °C function indicator illuminates.
5. Simultaneously press the
∆ and ∇ keys. The SET and MAINT indicators will
light.
6. While the SET and MAINT indicators are illuminated, use the
∆ or ∇ key to set
the display to the calculated Temperature Correction Value.

NOTE:
The °C light will pulse rapidly for a short duration to indicate it is not
operating in the factory default mode. It will pulse for a longer duration
and less rapidly (with a frequency of approximately one second) to
indicate temperature is more than one degree above or below setpoint.
To return to the factory calibration:
1. Press the SELECT key until the °C function indicator illuminates.
2. Simultaneously press the
∆ and ∇ keys. The SET and MAINT indicators will
light.
3. While the SET and MAINT indicators are illuminated, press the START/STOP
key.
4.8 Total Running Time
The control module of the Innova Shaker totals the time the shaker has been “ON” to
track hours of usage.
To display the accumulated running time:
1. Select HRS using the SELECT key.
2. Simultaneously press the
∆ and ∇ keys.
