1. Press and hold up arrow key to increase temperature, release key when
desired set point is obtained.
2. Press and hold down arrow key to decrease temperature, release key
when desired set point is obtained.
3. Once set, temperature control is initiated by pressing the heat on
button; the heater will react and start increasing the temperature to
reach the set point.
4. During operation, both the up and down arrow keys can be used to
adjust the temperature to a new set point.
The operating microprocessor possesses a non-volatile memory. Upon
resumption or recovery from an AC power loss, the following will be
noted:
• All readouts will flash until any key is pressed.
• If unit was shaking at the time of power failure, it will resume
operation at the speed and timer settings that were entered at the time
that AC power failed.
1. Fill a 250-ml Erlenmeyer flask with approximately 100 ml of water
and position it at the approximate geometric center of the shaking
platform.
2. Install a thermocouple inside the flask with the thermocouple junction
in direct contact with the water.
3. Adjust the safety thermostat to its maximum clockwise position.
4. Using the up and down keys, adjust the set point temperature to read
37ºC or any other desired set point.
5. Allow sufficient time for chamber temperature to stabilize.
6. Press HEAT ON button and, while continuing to hold, press and
release the HEAT OFF button. Now, release the HEAT ON button.
7. The decimal point should now be flashing indicating Calibration
mode.
