4.2 Display Probe Display when using external probe. Remote Display when using remote control. Rated value/Real value Display values in when heating or stirring or timer function is switched ON. Table 3 Note： If both heating and stirring functions have been started at the same time, heat display always has higher priority. If in this case speed is changed via the stirring knob, it displays stirring speed and reverts to temperature after 5 seconds.
• • • • • • • Set the target stirring speed and begin. Observe the stirring bar and LCD display. Set the target temperature and start heating. Observe the real temperature on LCD display. Set the timer. Timer ends, the heating function stops. Stops stirrer function. If these operations above are normal, the device is ready to operate. If these operations are not normal, the device may be damaged during transportation, please contact manufacturer/supplier for technical support.
6.1 Working with the PT1000 external temperature sensor following at this time: • • Turn off the power Ensure the external temperature sensor is positioned sample container correctly • Turn on the power, set the target temperature and switch on the heating function • If the unit is still not functioning correctly, please contact manufacturer/supplier 6.2 Residual heat warning（HOT） Figure 6 The PT1000 external temperature sensor is the manufacturer’s optional accessory.
7 Stirring 9 Remote Control The “stirring” function is switched on or off via rotating stirring knob. The speed is set on the knob (100 to 1500 rpm in steps of 10 rpm). When both the heating function and stirring are switched on and the above operations are completed, the LCD will shift to the speed value and revert back to the temperature value in about 5 seconds. The last speed value set is displayed.
