CANNON Instrument Company | CT-500 Operation 23
To heat the bath more rapidly, turn on the PREHEAT ( PH ) switch. If the target temperature is below
80 °C, turn the PH switch off when the desired temperature is reached. For temperatures above
80 °C, keep the
PH
switch ON to maintain temperature control. When the
PH
switch has been
turned on, the PH - HEAT LED will light.
3. As the bath temperature approaches the selected T - SELECT setting, the LED above the TA
controls will start to blink as the heater duty cycle is automatically adjusted to stabilize
temperature.
If the auxiliary heater was engaged, the PREHEAT light will also blink. Make sure to turn off the
PREHEAT
switch if operating at temperatures below 80 °C.
4. Insert the appropriate thermometer for the test temperature (see
Appendix IV - Thermometry
for the CT-500
for thermometry information).
5. To adjust the bath temperature to the exact temperature desired, first unlock the TA - FIXED
dial.
6. Read the thermometer to determine the actual temperature of the bath. Make sure that both
the bath temperature and thermometer have stabilized before taking a reading.
7. Turn the TA - FIXED dial to adjust the temperature. After each adjustment, allow several minutes
for the bath temperature to stabilize.
8. Turn the dial clockwise to increase the bath temperature or turn the dial counter-clockwise to
decrease the bath temperature.
9. When the desired temperature has been reached, re-lock the TA - FIXED dial.
10. After the bath has reached the desired temperature, set the HIGH TEMPERATURE LIMIT
CONTROL (LC) . This will prevent the bath from overheating if a malfunction occurs.
Adjusting the High Temperature Limit Control
During this procedure, the temperature of the bath may change slightly, but will quickly recover.
1. Using a screwdriver, slowly turn the LC - TEMPERATURE ADJUST control counterclockwise until
the OVER TEMP message lights up on the LC - PUSH TO RESET button.
2. Turn the control clockwise approximately ¼ to ½ turn.
3. Push the LC - PUSH TO RESET button. If the bath doesn't recover, repeat step 2 and try again.
