Overview
DB-3-200-01 and DB-3-130-01 are designed to accommodate three different format aluminum blocks. And it comes with block handling tool (see Figure 2) and glass thermometer.
DB-3-200-01 has the digital display and simple operation buttons to fit the needs of users in
the lab and has two lights to indicate the status of the operation and process.

Operation of Analog Unit
1. Select the appropriate block. Make certain that the block is clean on all sides as well as
the hot plate of the unit. This will ensure proper heat conduction.
2. Place the block into the well of the unit and insert the proper tubes into the block. Make
sure there is a good fit between tube and well.
3. Plug in Mains Cable and turn the unit on in the back of the unit.
Setting Operating Temperature Analog Unit
1. Turn the Temperature Control Knob on in the front of the unit to the required setting
(OFF or 1-9). The actual temperature of the block depends on the type of block and fit.
Thermal contact between block and unit is crucial for best results.
2. Different designs of insert blocks may cause actual temperatures to vary and speed of
heating to vary. Place a thermometer in the special thermometer hole in one of the
aluminum blocks to indicate proper temperature.
3. The unit will heat if the set temperature is higher than the current block temperature.
This will be indicated by the heater indicator light.
4. The heater indicator light will begin to flash when the set temperature is approached. It
will flash more slowly when the temperature is beginning to stabilize.
Please note there will be a lag time between the heater and the block.
Operation of Digital Unit
For the digital: DB-3-200-01, DB-2-200-01, DB-2-200-02 and DB-1-200-01:
1. Put the block into the blocks compartment (see Figure 1A), use block handling tool
(Figure 1B) to add and remove the block
2. Plug the power cord to the source, and make sure that the plug is firmly pressed. Turning
on the switch on the back, and the light in the front will be on. The light will be flashing until
the temperature reaches equilibrium. Use thermometer measuring the temperature, turn
the knob to adjust temperature. Leave the Heated Block on to keep the temperature at
stable level. It takes sometimes to reach the equilibrium.
ALWAYS KEEP THE MACHINE AWAY FROM DRAFTY AREA TO AVOID THE EFFECT OF THE
ENVIRONMENTAL TEMPERAURE ON THE TEMPERATURE CONTROL OF THE BLOCK HEATERS!

2. Plug the power cord to the source, and make sure that the plug is firmly pressed. Turn on
the machine by switching the on/off switch (see Figure 2).

3. When turning on the machine, the display will immediately show “_ _ _ _”, and then
shows the actual temperature in Celsius. The “power” light is off at this time. And when the
block temperature is over 50 ˚C, the “heat” light is on, otherwise, it is off, too.

4. Setting Operating Temperature:
- Turn the Temperature Control Knob on in the front of the unit to the required setting (OFF
or 1-9). The actual temperature of the block depends on the type of block and fit. Thermal
contact between block and unit is crucial for best results.
- Different designs of insert blocks may cause actual temperatures to vary and speed of
heating to vary. Place a thermometer in the special thermometer hole in one of the
aluminum blocks to indicate proper temperature.
- The unit will heat if the set temperature is higher than the current block temperature. This
will be indicated by the heater indicator light.
- The heater indicator light will begin to flash when the set temperature is approached. It
will flash more slowly when the temperature is beginning to stabilize.
- Please note there will be a lag time between the heater and the block.
5. Press “Start/stop” button to start the operation. The “power” light is on and “heat” light
is flashing at this point. When reaching the equilibrium, the “heat” light is steady on. The
equilibrium point is set @ 0.1 degree of the accuracy. It might take longer time to reach.
Caution: when putting the cold test tubes or other vials, it may cause the tubes/vials
to break!
6. When running, i.e. the “power” light on, the set point of the heated block could not be
changed. To change the set point of the temperature, press “Start/stop” button to stop the
run (the “power” light will go off), and then change the set point as indicated in the step 4.
7. The DB-3-200-01 always shows the actual temperature reading. To see the set point
temperature, press the “Set” button, and the LED will show the set point temperature.
8. After use, wait until the block cool down to below 50 degrees (the “heat” light is off) and
turn off the block heater.

Calibration
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
7
process interrupted between stage 4 and 5, then the machine will take the previous 4 points
data as the calibrated value, and becomes 4-points calibration.
7. During calibration, the calibration set point could not be changed unless interrupting the
process by pressing the “Start/stop” and “mains” knob as indicated in the step 3.
8. Always using the same type of the block to avoid the discrepancy. The calibrated
displayed value only accurately indicates the value of the block/vial that actually measured
from external temperature measurement device.

Please make sure that the correct channel corresponding to the designated block
before to do the operation. The DB-2-200-02comes with additional LED display
and “sel” button for users to select the channel. All operation and calibration is
the same as in DB-3-200-01, but before to do that, please press the “sel” button to
select the channel (the LED light will be ON when the channel got selected).
