Beijing grounded aging tester

instrument performance

1. Power Supply:220VAC 50Hz(Ensure reliable grounding of power ground wire and chassis grounding)

2. Power:<300VA

3. Temperature control range:50~380℃

4. Temperature control accuracy: ± 2 ℃

Usage:

APreparation before use

1. Before using the instrument, connect the "air inlet" to nitrogen gas to ensure that there is no air leakage at the joint;

2. Connect the "outlet" of the instrument to the outdoor pipeline;

3. Insert the power cord into the power slot;

4. Insert the heating plug into the heating slot;

5. Open the shut-off valve and adjust the needle valve to achieve the desired flow rate.

BDaily use

1. Set timer time

2. Press the 'Settings' button (time should not exceed)7In seconds, the * of "Set Timer Time" starts flashing, and pressing the "Increase" button can change the value of that digit; Press the 'Settings' button again, The second digit of "Set Timer Time" starts flashing, and pressing the "Add" button can change the value of that digit; Similarly, set the scheduled time, such as timing15In minutes, the 'Set Timer Time' needs to be set to“00：15”. After the setting is completed, do not operate any buttons and wait10In seconds, the timer will remember the time set by the user and does not need to be reset again in the future (even if powered on again), unless the user needs to modify the timing period.

3. Start timer

4. Press the "start button" to start the timer. At this time, the "timer work indicator light" (red light) flashes, and the "actual timer time" display starts to increase. When the scheduled time is up, the "timing work indicator light" (red light) stays on, the "timing completion indicator light" (green light) lights up, and the buzzer prompts10second.Press the 'start button' again to start the next timer.During the timing process, if you press the "pause button" to pause the timing, lift the "pause button" to continue the timing.

End of use

1. After activation, place the adsorption tube on the front bracket of the heating box and cool it down before removing it.

2. Turn off the power.

3. Close the shut-off valve.

General fault diagnosis and handling methods

1. Fault phenomenonAfter the power switch is turned on, all displays do not light up

2. check：1）Has the power plug been plugged into the powered one220VACOn the power box; 2）Is the fuse broken.

3. Corresponding handling methods：1）Insert the power plug into the powered one220VACOn the power box 2)Replace the fuse

4. Fault phenomenonThe "temperature indicator" displays as garbled or negative hundreds of degrees Celsius

5. cause of failurePlatinum blocking or short circuiting of temperature measuring components

6. Corresponding handling methodsCheck if the connection between the heating plug and the heating slot is loose. If so, tighten it. If not, replace the platinum resistor or disconnect the short circuit.

7. Fault phenomenon: Joint leakage

8. Corresponding handling methodsTighten the joint, and if it still doesn't work, replace the sealing ring.

9. Fault phenomenon: Timing disorder

10. Corresponding handling methodsPress the 'Settings' button8More than seconds, until the 'actual timing time' is displayed as“XX-X”At this time, the value is the working mode of the timer. The "Set Timer Time" display is empty. By using the "Set" and "Add" keys in combination“XX-X”Set as“09-2”Then wait10Second, the timer's working mode has been set. Then reset the timing.

11. AttentionWhen there is no timing disorder, do not easily modify the working mode of the timer to avoid unnecessary errors.
