WN10Temperature Error Calibration of Test Tube ThermostatMethod Introduction

WN10 Test Tube ThermostatIt is a new product controlled by a microcomputer, which can be widely used for sample preservation and reactionDNAPre denaturation of amplification and electrophoresis, serum coagulation, etc.

The temperature of this instrument has been calibrated before leaving the factory. However, due to certain reasons, the actual temperature andThere is a deviation between the displayed temperatures, and the following methods can be usedCorrect temperature errors;

Attention! In order to ensure the accuracy of temperature, this instrument adopts a two-point temperature calibration method, that is40℃ and100Two point temperature synchronous linear calibration method at ℃. After two-point temperature linear calibration, the system ensures that the temperature accuracy of other temperature points is ≤±0.5℃。

When calibrating the temperature, the ambient temperature and module temperature must be lower than35℃.

Use a thermometer for calibration, the specific operation method is as follows:

a)After turning on the instrument, enter the waiting interface and observe the temperature display window temperature to confirm that its temperature value should be less than35℃。

If the temperature is higher than35℃, wait for the temperature to drop35After reaching ℃, proceed with the following steps.

b)Inject paraffin oil into a conical hole at the center of the module and place a thermometer (with a required accuracy of) in the conical hole

0.1℃, the temperature sensing bulb of the thermometer must be able to penetrate into the conical hole

c)Press firstStopPress and hold the key, then press the temperature again q Key and hold together3After a few seconds, enter the temperature calibration interface, as shown in the figure on the right.

At this point, the time display window shows as“ ”, indicating that the temperature calibration program has been entered; The temperature display window shows the real-time temperature and automatically starts heating up to40.0℃。

When the temperature rises to40.0After maintaining a constant temperature of ℃, the decimal places begin to flash and wait40The temperature calibration value of ℃. Require constant temperature20After minutes, read the actual temperature measured by the thermometer.

Shanghai Five Phase WN10 Test Tube ThermostatAttention! To ensure temperature calibration accuracy, it is recommended that users maintain a constant temperature20Read the measured temperature in minutes!

If the value read by the thermometer is39.6℃, according to q or p Press the key to modify the temperature value in the temperature display window, so that the temperature value is39.6， pressStart Confirm the input value with the key.

d)Then the instrument automatically heats up to100℃, in100Wait for the input temperature calibration value after maintaining a constant temperature of ℃. Same requirement for constant temperature20After minutes, read the actual temperature measured by the thermometer.
