Make sure to turn the H - HEAT switch off when the desired temperature
has been reached. Otherwise, the temperature stability of the Bath will
not be optimum.
4. If the bath fails to equilibrate within 0.01°C of the desired control
temperature, release the lock on the TA - FIXED dial.
5. Turn the TA - FIXED dial to adjust the temperature. After each
adjustment, allow several minutes for bath temperature to stabilize.
Turn the switch clockwise to increase the bath temperature. Turn the
switch counterclockwise to decrease the bath temperature.
6. When the desired temperature has been reached, relock the TA -
FIXED dial.
You may wish to record the dial setting and temperature for future
reference in the event that it is necessary to alter the position of the TA -
FIXED dial for control at a different temperature setting.
If the desired preset temperature cannot be obtained by adjusting the TA
- FIXED dial, make sure that the TA - SELECT switch is set to the left
position. If the temperature still cannot be attained using the TA - FIXED
dial, it may be necessary to adjust the small trimpots below the front
panel (see Adjusting Trimpots, next page).
1. Turn the T - SELECT dial to the temperature closest to the desired
temperature.
The green LED on the right side of the front panel will glow while the
cooling units are operating. This light does not mean that the bath is at
the proper operating temperature. Do NOT use this lamp to gauge the
temperature of the bath. Always use the thermometer in the bath to
confirm bath temperature.
2. Move the TA - SELECT switch to the right (the VARIABLE position).
3. If the desired temperature is warmer than the present bath tempera-
ture, turn on the H - HEAT switch . When the switch is turned on,
the HEAT LED on the front panel will glow continuously until the
desired temperature is reached. To achieve temperature stability more
quickly, turn the H - HEAT switch off approximately 2-3°C before
your temperature probe indicates the desired temperature.
Make sure to turn the H - HEAT switch off when the desired temperature
has been reached. Otherwise, the temperature stability of the Bath will
not be optimum.
4. After the bath equilibrates, release the lock on the TA - VARIABLE
switch.
