The digital types of Block Heaters can easily be calibrated to show any blocks/vials and

tubes' temperature in the displayed LED. Due to the differences in the mass of the various

aluminum blocks, environmental air temperature, thermal radiation, and many other factors,

the Block Heater may need to be re-calibrated when switching different blocks and when the

environmental changed. The DB-3-200-01 has been calibrated based on 16 mm Blocks.

DB-3-200-01 can be calibrated using one to five points. The calibration steps are described

in the followings:

1. Prepare the thermistor, or thermometer temperature measurement devices. You can

calibrate the block or even the temperature of the solution in the vials/tubes. Make sure

the thermistor or sensor well contacted with the blocks or vials/tubes solution.

2. Calibration could not be made during running (i.e. the "Power" light on). Press

"Start/stop" button first to stop run if the machine is running.

3. Press "mains" turning knob (please note that it should be "press" not "turn") first, then

press "Start/stop" button, simultaneously release both, the display will show "C _ _ X",

which X indicates the stage of the calibration. For example, in the first calibration, it will

display "C _ _ 1".

4. Press "set" button, and turn the "mains" turning knob to the desired temperature

calibration point, release the "set" button, and press "mains" to start the calibration. In this

time, the "power" light will be on, and the "heat" light will be flashing. The display showed

"C _ _ X" flashing.

5. When reaching the equilibrium set temperature, the display will stop flashing. In this

stage, you can enter the actual block or vial temperature from reading the block or vial

temperature from external temperature measurement device: Press "set" button and

turning the "mains" knob to the actual temperature value, release the "set" button, and

press the "mains" knob. The machine will take the real value to take effect in the next run.

In this case the CL-201 will display "C _ _ X+1" (X + 1 indicates the next number of the

calibration stage) and continue to flash: Repeat the step 4 to enter the next calibration set

temperature.

The maximum calibration point is five. When finishing five point of the calibration, the

machine will automatically exit from the calibration program and return to the pre-start

status: the "power" light will go off and the "heat" light will go "on" when temperature is

over 50 ˚C.

6. The calibration can be interrupted anytime by pressing "Start/stop" button and "mains"

knob as indicated in step 3: If the process interrupted before the completion of the

calibration stage, the machine will only take the previous calibration point. For example, if

the process interrupted between the first and second point calibration stages, then the

machine will take the first calibration point and becomes one-point calibration; If the

Calibration
