Low temperature testing instrument with high reliability and long service life, speed, stability, low noise characteristics, coupled with efficient transmission mechanism, the device has a delicate and light, easy features.
Cold flexibility test instrument use
1. According to the coil type and specifications change move the test rod of the corresponding diameter.
2. To cool to the appropriate temperature of the sample placed on the test machine of moving test and static test between the bars.
3. In the entire test into the coolant, and cover on the freezer door.
4. Enter the controller parameters to be measured. Method of the parameter settings.
5. Confirmation (auto/manual) switch to automatic party (run) button, move right on the test stick will enter the State.
6. If the coolant temperature has not reached the testing temperature, the controller will shut down normally open contacts, controlling the freezer continues to run if the temperature has reached the testing temperature, the controller according to the preset time delay.
7. When the time to, the controller will decide based on coolant temperature as follows: If the temperature has to, the controller output contacts are disconnected, freezer stopped cooling, start the test. Now move the test rod will reveal surface, (pictured below) such as temperature fluctuations, and did not reach the preset temperature, the controller output contacts are closed, cool the freezer of frozen liquid can be continued until the temperature falls below the set value, freezer stopped cooling, start the test.
8. Test is complete, the controller alarm. Staff open the cover on the freezer, Visual test results, and take samples.
