NOTE
Do not operate the TE-1500 with an inadequate volume of liquid in the
bath vessel.
3. Turn on the LIGHTS switch on the front panel and verify that the
lamps illuminating the interior of the bath are on.
There are two ways to set the TE-1500 Bath temperature, preset or
custom temperature selection. Both procedures are described in the
following sections. If the desired bath temperature corresponds to a value
on the Temperature Select switch, use the Pre-Set Temperature Selec-
tion procedure. If the temperature is not one of the Temperature Select
switch values, use the Custom Temperature Selection procedure.
Note that dials and switches are identified with their control area abbre-
viations. For example, TA - FIXED refers to the left-hand dial (marked
FIXED) in the TEMPERATURE ADJUST section of the control panel.
Both Temperature Adjust dials on the
TE-1500 are equipped with dial locks
(see Figure 8) to prevent accidental
changing of dial settings. Push the
lock upward to release the lock and
move the dial. When the dial has
been set to the proper position, push
down on the lock to relock the dial.
Before beginning the temperature
selection procedures, release the dial
locks on the TA-FIXED and TA-
VARIABLE dials and set the dials to
their midpoints (500). Then relock the
dials.
1. Turn the T - SELECT dial to the appropriate 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 left (FIXED) 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.
