Metal detector troubleshooting method
Phenomenon 1:
Symptom: alarm or vibration after 1-2 seconds of power on
Analysis of the cause: This phenomenon usually occurs due to high sensitivity and insufficient power. Some users do not notice that the battery voltage is lower than the working voltage after using for a period of time. It is often considered that the detector is not only used as a fault repair.
Method of exclusion:
1. Adjust the sensitivity when the alarm is turned on, until it is not alarmed.
2, the adjustment can not be excluded, replace the battery or use after charging.
Note: Turning down the sensitivity at this time does not affect the detection accuracy.
Phenomenon 2:
Symptom: A detector with vibration, sometimes the buzzer works normally, and when it is turned to vibration, the vibration motor cannot stop.
Analysis of the cause: This kind of phenomenon is generally caused by the user not paying attention to the voltage drop after using for a period of time. Because the motor consumes more power than the buzzer, the voltage at this time can only ensure that the buzzer works normally.
Method of exclusion:
1. In the case of vibration, reduce the sensitivity.
2. Replace the battery with a new one or charge it.
Note: Turning down the sensitivity at this time does not affect the detection accuracy.
Phenomenon 3:
Fault phenomenon: the red light on the boot is long, no alarm, no vibration
Analysis of the cause: This phenomenon occurs, the detector is generally disabled for a period of time, forgetting to remove the battery, the battery is slowly discharged for a long time.
Method of exclusion:
1. Just replace the battery with a new one.
2. Pay attention to whether the battery box is contaminated by the battery leakage. If the pollution is to be cleaned in time, the battery buckle or circuit board will be corroded and damaged.
3. It can be cleaned with pure alcohol or with special electronic cleaner.
Phenomenon 4:
Symptom: After detecting anything, it will alarm or slightly shake and alarm.
Analysis of the cause: Generally, the sensitivity is adjusted too high, or after detecting the fine metal with high sensitivity, it is not adjusted to the original normal position in time.
Remedy: 1. Just lower the sensitivity.
Phenomenon 5:
Symptom: It appears normal and normal after booting. It is not normal. It will alarm for a while, and there will be no response for a while.
Analysis of the cause: Generally, when the user installs the battery, the battery buckle is not pressed or only one is pressed, and the other is not touched when contacted. There are also some battery buckles that do not match the battery and appear loose contact.
Method of exclusion:
1. Open the battery compartment and re-tighten.
2, the battery buckle is too loose, just use the pliers to gently clamp.
3. If the battery buckle is not elastic or damaged, replace it. Pay attention to the +- polarity when replacing.
Phenomenon 6:
Symptom: GC-1001 is special, and it will appear long after power on or later.
Analysis of the cause: The detector does not need to be adjusted, and the switch is also special: it is high sensitivity forward, backward (cannot lock) for lower sensitivity, and the middle is closed.
Remedy: When there is a howling, just press the "RESET" reset button in the middle of the front of the detector to eliminate it.
Phenomenon 7:
Symptom: The position of each type of sensitivity adjustment hole and how to adjust the sensitivity.
Cause Analysis:
1. The adjustment hole of MD-8 is at the front end of the battery cover on the back of the detector, and the small yellow screw in a small hole;
1. All: Increase sensitivity in a clockwise direction and reduce sensitivity counterclockwise.
2. Only the MD-8I needs to be adjusted with a micro screwdriver, and it is adjusted directly by hand.
This type of anti bedsor air mattress will be with Turn over and toilet functions. More comfortable for the patients and lesser labour taking for the nursing people.Dynamic mattress overlays utilize a power source to constantly alter the level of support, while static overlays reduce pressure by spreading the user`s weight over a larger area through the use of consistent inflation. All hospital bed overlays are intended to increase comfort for patients and help reduce the constant pressure on bony prominences of the body, as it is this constant pressure that leads to the development of pressure ulcers.
