NF-5120 Wall Pipe Blockage Detector

Your eacellent helper in cable test!

Please read the safety precautions before using or repairing this equipment.

• After use, please turn off the power supply
• Because the device uses electromagnetic for detection, there may be noise interference when it is close to the electric wire, electronic devices or electric radiation
• When detecting metal pipes, the detection distance will be reduced due to electromagnetic shielding(the detection distance of 3mm thick iron pipe is about 15-20cm)
• If the blockage is found, please take back the detecting cable before digging
• Please use standard 5V power adapter and micro_ USB cable to charges the instrument.
• If it is not used for a long time, please keep it after full charge. It is recommended to charge the battery once every half a year to protect the instrument battery and prolong the service life

Overview

The instrument can be used in all kinds of scenarios, caused by various reasons of iron pipe, PVC pipe,
Plastic pipe, cement pipe, steel pipe, copper pipe and other metal and non- metal pipe blockage.Can be
Quick and accurate positioning of the plugging point of the pipeline buried in the cement wall, floor and land.

Functional features

1.1The emitter

• Probe Self Checking
  Open/ Short circuit Open circuit: Twice “Di” for fault notice Normal; Single long beep “Di”,the probe enters the working mode Charging indicator function: red light when charging, green light when full.

• Low power alarm and battery protection function: low voltage (1t3.6V), green light flashing alarm, ultra-low pressure (&1t:3.4V), the instrument a_utomatically shuts down to protect the battery.

• Automatic shutdown function, automatic shutdown after 1 hour, to prevent forgetting to shut down resulting in power depletion

1.2Receiver

• Power detection function: automatically detect the battery power turning on, represented by 5 LED lights, all on means full power

• Charging indicator function: the red light is always on during charging;Full, always green

• Power alert function:
  Normal power: green light is always on and low voltage (&1t;3.6V), green light 1 second slow flashing alarm, ultra-low pressure (&It;3.2V), the green light flashes for 3 seconds and then turns off to protect the battery

• Automatic shutdown function: Utomatic shutdown after 30 minutes, to prevent forgetting toshut down resulting in power depletion

• Indicating function of signal intensity:
  The signal lamp can accurately indicate the signal intensity, and has the function of brightness adjustment

• The detection range is adjustable from 5 cm to 50cm

Specifications

How to use the product

3.1.Turn on and off the transmitter:

• Press the power button for 2 seconds in the off state, when the power indicator is green, otherwise it will be turned off
• Receiver: turn the knob clockwise to power on the battery in thefirst 2 seconds after power on, using 5 LED to represent the battery, all of which are fully charged

3.2Pre-use inspection.

• Transmitter: turn on and spin the probe out for a while, and the probe is at a distance from the transmitter.
• Receiver: power on to the maximum sensitivity, put the receiver close to the transmitter probe, if the receiver emits a strong signal sound, it means that the instrument is normal, such as the receiver does not make sound or the sound is very low, the probe needs to be replaced.

3.3Start detection (figure 3-1)

• Transmitter: put the transmitter probe into the pipe, turn the transmitter turntable handle line into the pipe, until the emitter pipeline feels the resistance and cannot go further into the pipeline, then the position of the transmitter probe is the blocking position
• Receiver: adjust the receiver sensitivity to the maximum, move the receiver transmitter probe closer along the pipe, the stronger the signal received, the more signal strength indicator lights up, the louder the tone
• The strongest signal is the blocking point. In some usage scenarios, there may be ambient noise, so that the sound emitted by the receiver cannot be heard clearly and headphones can be used to work

Tips: use high sensitivity, quickly locate the approximate position of the plugging point, and then adjust the sensitivity to locate the plugging point accurately. 3.40utgoing / unwinding method

1. Correct exit / take-up: turn the wheel clockwise / counterclockwisewith the right hand after lifting the instrument with the left hand.
2. Wrong take-out / take-up: lifting the instrument with the left handand pulling the wire out with the right hand and pushing the wire in will cause the pipeline to get tuck or even break

Probe replacement method

1. Remove the parts to replace the probe
   1| 502 glue| 2| Large heat shrinkable tube
   ---|---|---|---
   3| Protective sleeve| 4| Thin copper tube
   5| Probe| 6| –
2. Use the tool to subtract the damaged probe part of thesignal receiver.
3. Peel off the 5mm of the signal wire (remove the rubber from the fiber core).
4. Connect the wire core with tiny cooper tube by clampping the bottom part of the tube
5. Insert the probe and clamp the thin copper tube with pliers and put the heat shrinkable tube
6. Put on the protective cover and drop 502 glue
7. Put on a large heat shrinkablepipe lighter
8. Complete probe replacement

further testing
Launcher not activated| Check the transmitter for boot
Transmitter probe damaged| Replace probe
Non-signal noise from receiver| Strong electromagnetic interference nearby| Test to empty areas of useless appliances
The charger may cause electromagnetic interference to the machine| Do not use the machine while charging
Non-signal noise from receiver| Poor contact with charging interface good contact| Please check thecharging line is in
Damage to charging line| Please change the line and test again
Receiver battery contact poor| Please plug in the battery interface
Power indicator flashing| Low battery power| Please charge and test again
If the above-mentioned failure occurs, or above solution is invalid, please contact the customer to resolve it
