(2). Program Operation

(a). Continuous Heating Mode (Timer sets as 00:00)

Note 2. (a).

(1) Controller will memorize the selected program and maintain when it switches on next time.
(2) TE represents the reading of external temperature sensor and shows” –” if no sensor is connected.
(3) How to stop or select other programs: Press / the screen shows”STOP HEATING7″ message. Press O to stop heating and return to program list, press / to continue heating.
(4) 00:00 stands for continuous heating. The counter will stop until 99:59 ,whereas hotplate maintains heating continuously with heating indication, stop heating by pressing / .

(b). Countdown Mode (Timer should not be set as 00:00)

Note 2. (b).

(1) Controller will memorize the selected program and maintain when it switches on next time.
(2) TE represents the reading of external temperature sensor and shows” –” if no sensor is connected.
(3) How to stop or select other programs: Press / the screen shows”STOP HEATING1″message. Press O to stop heating and return to
program list, press / to continue heating.

(3). Parameter Setting

(4). Temperature Calibration
Insert electronic thermometer into hole for reference sensor. Calibrate temperature as following procedure.
Please make sure thermometer and temp. setpoint is calibrated regularly or certified by standard organization to ensure the accuracy is ±1 “C.

Note 4.

Please set the calibrated setpoints before calibration, refer to (3) Parameter Setting.
TE represents the reading of external temperature sensor and shows “—” if no sensor is connected. Press 0 to calibrate the reading of sensor when sensor is connected.
If the actual temperature is higher than setting temperature, a cooling progress appears.
To stop calibration, press / and screen shows “STOP HEATING7” message. Press O to stop heating and return to program list, press / to continue calibration.
When connecting an external PTFE temperature sensor, press O to switch the calibration parameters of hotplate and external sensor. Press or to adjust the temperature while the figure is flashing, and hold O for 1 second to save the parameters and go for next step.
Error message (“Cal-# Error”) appears if calibration is error. (eg. T2 temperature is lower than Tl). Press any button to reset to default calibration settings automatically.
With an unsatisfied calibration result, you can re-calibrate or select the “Rst” program and press / to reset to default calibration settings.

Maintenance

Please unplug the instrument and cool it down before cleaning.
Please operate the instrument in a well-ventilated area and keep it clean. If there’s any solution drop or splash to hotplate, block, heating cable and controller, please clean the surface with damp cloth or mild soap after cooling to room temperature.
