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!
