Brookfield Bath, Model TC-101 Digital KU-1 Viscometer - Manual (Page 7)

Although stability is better at the external apparatus control point, depending on the insulation and
length of tubing used, the accuracy of temperature may be slightly different than the temperature
indicated in the reservoir.
2.6 Power
Plug the unit into a properly wired, grounded outlet with the same voltage and frequency indicated on
the identification label on the back of the unit. With the Power switch OFF, the display indicates
standby mode (....). If there is no response, check if the circuit breaker is in the ON position.
Use of an extension cord is not recommended, but if necessary, use one that is properly grounded and
handles the total wattage of the unit. The extension cord must not cause more than a 10% voltage drop to
the circulator.
2.7 Setting the Temperature
After filling the reservoir with fluid, set the temperature:
1. Set the Safety Thermostat (OTP) knob on the rear panel to full clockwise position, then press the
Power switch ON. The pump starts to operate. The LED display indicates the power up self-test
(8888). You are now ready to set the front panel controls to the desired temperature setting.
2. Press the SET/ENTER button. The degree light flashes indicating the temperature can be changed.
3. Turn the INCREASE/DECREASE knob to the desired setting. This setting is accepted after
pressing the SET/ENTER button or automatically accepted after a few seconds. The degree light
stops flashing and the display indicates the actual bath temperature.
The set temperature may be checked at any time by pressing the SET/ENTER button. Allow sufficient
time for the bath to stabilize at the desired temperature.
If you are unable to raise the set temperature, it is possible that the High Limit is set lower than the set
temperature you have selected. If this happens, set the High Limit to be 1°C or more higher than your
desired temperature.
2.8 Setting the High Limit
This feature provides additional set point security by allowing a selectable upper limit set point. If the
fluid reaches the high limit, the unit will shut down and display "HI-L" until the fluid temperature is
reduced or the "HI-L" value is raised. The "HI-L" should be at least 1°C higher than the selected control
temperature to avoid unwanted shut down during regular operation.
