standby mode, press and hold the “Pause” button and press the Standby
button. Release the Standby button first, and then release the pause
button. To restore normal beeper operation, remove AC power to unit for
10 seconds and then restore.
CALIBRATION:
Speed:
1. Enter the “Standard” mode using the steps identified above.
2. Set the speed to the desired calibration point.
3. Press and hold the Standby (A) button and press the Start (H) but-
ton. The Program display (G) will be flashing.
4. Using a tachometer, enter the measured value using the Program
Speed Selection arrows (I)
5. Press the Standby (A) button to save. The shaker is now calibrat-
ed for this speed.
Temperature (Single Point Calibration):
1. Enter the “Standard” mode using the steps identified in Mode
Selection. (page 5)
2. Using a Fine Wire Thermocouple, place the wire in the center well
of block B. If you were loading a PCR plate with the letters hori-
zontal and at the top and the numbers were vertical and to the left,
the position would be D7. Although this position is not critical to
the calibration, consistency is, when verifying a calibration.
3. Set the temperature to the desired calibration point and press the
On/Off (C) button to start heating or cooling.
4. Allow temperature to stabilize for at least one hour. The lid should
remain closed during calibration.
5. Press and hold the Standby (A) and press and hold the Temperature
Up arrow (C).
6. The display value will flash
7. Using the Temperature arrows, enter the value that was measured
using the external temperature device.
8. Press the standby button (A) to save and exit the temperature cal-
ibration mode. The decimal point in the temperature display will
flash indicating a single point calibration is being used.
Up to 3 single point calibrations (SPC) can be stored. The unit will now
use the biased offset for that specific temperature setting and increase
and decrease temperature accordingly to bring the temperature to set
temperature. All other temperature settings will use the standard inter-
nal calibration. This offset will be stored in memory and retained until
reset.
To delete a SPC, the SPC set point should be in the Temperature display.
(there will be a flashing decimal point) Press the Standby (A) and
Temperature Down arrow (C). The unit will beep 2 times to indicate the
deletion is complete.
USE DEFINED PROGRAM MODE:
Program Details - Limitations:
1. Up to four (4) programs can be entered.
a.
The programs are stored until deleted from memory.
b. The total number of program steps allowed is 48. This total
is shared by all four program modes.
2. Individual program steps cannot be inserted or deleted once a pro-
gram is entered.
3. Program steps cannot be edited while the program is running.
4. All program steps are sequential and “Looping” is not allowed.
5. The operator MUST ALWAYS press the “Start” button to start the
next program step.
6. If the temperature control is On, the temperature will be main-
tained between steps.
7. The shaker will always stop at the completion of a step.
