1. Turn on the power of the high and low temperature test chamber, turn on the circuit breaker at the back of the electric control cabinet, and the "stop" point on the control panel.
2. Press the "Start" button, the controller displays, press the "SET" button according to the "SV" value on the controller, the end of the SV value flashes, and the "<" key can be used to move the cursor to the digit to be modified. Then use the "∧, ∨" keys to set.
3. When it is set to the required test value, press the "SET" key to confirm. If the test value is lower than the room temperature value, please press the "cooling" switch on the control surface, and the test can be carried out. After three minutes, the cooler is turned on. If the test value is higher than the room temperature, the setting is complete. The controller will execute automatically, without pressing any switch, if you need to do humidity, press the humidity switch (refer to this manual for the specific operation of the controller, but the internal settings of the controller must not be changed arbitrarily, otherwise it will affect the entire test)
4. When the "AL1" indicator light on the controller of the high and low temperature test chamber is on, the temperature in the working room has exceeded "50℃" and the refrigeration cannot be turned on. Only when the PV value drops below 50°C, the refrigeration switch can be turned on, and observe There is a lighting lamp on the window. If you need to observe the test piece in the test, you can turn on the "lighting switch". There is a test hole on the left side of the box, which can provide the test piece for the dynamic test of the wire, but for the low temperature test , This hole must be sealed with thermal insulation material (in the case of lead wire), so as not to produce a large cold bridge, which will affect the test, and it is not necessary for reference in the high temperature test.
Finally, be sure to follow the instructions during the operation. If you have any questions, please contact the manufacturer for technical guidance in time to ensure the service life of your high and low temperature test chamber.
