Underground Cable and Pipe Detector

HM9800 underground cable and pipe detector is used to detect the location and depth of underground cables, optical cables, and metal pipelines. the detector is also suitable for pipeline units such as communications, telecommunications, electricity, cable television, water supply, and gas.

HM9800 Underground Cable and Pipe Detector adopts two gain modes: automatic real-time gain and manual gain. It displays peak and valley signals at the same time. One-click direct reading test depth and one-key direct reading of current value. the operation is simple and convenient.

The HM9800 Underground Cable and Pipe Detector is equipped with an external sheath fault location function. The transmitter can output a 4.8Hz fault location frequency. The A-frame can accurately find and locate the fault point of the cable and the outer sheath of the optical cable.

Optional accessories "sonde " can detect and locate non-metal drainage pipes.

The cable and pipe detector can automatically select the best search frequency, automatically measure the loop resistance, and the continuous automatic impedance matching function ensures the best signal output.

The receiver of the detector can receive two passive frequencies and two active frequencies. Intelligent operation instructions such as automatic real-time gain adjustment and left-right direction indication make it the easiest locator to use.

◇Real-time continuous automatic gainTM and manual gain

◇Simultaneous display of peak and valley signalsTM

◇Sensitive left/right indication functionTM

◇One key direct reading current value

◇One key direct reading sounding

◇Transmitter automatic matching impedance

◇Automatically select the best frequency function

◇Tri-frequency signal output function, excellent mixing function

◇Built-in ohmmeter can measure line resistance and grounding

◇Smart transmitter and receiver have voice and graphic instructions

◇The fault location range of the outer sheath is wide, ranging from 0 ohm to 5 megohms, covering various faults of the outer sheath of the optical cable with precise determination points

A-frame(optional)
	The A-frame accessories is used to detect ground fault on pipes and cables.In the case of pipes,the fault consist of coating defects.In the case of cables,faults are usually caused by insulation damage allowing the metallic sheath(or internal conductor) to become in contact with th ground.
Remote antenna(optional)
	The remote antenna can be used to help identify a particular cable on a cable tray or where cables are bunched together
Loc-10Tx Vehicle power lead(optional)
	12V DC,30ft(10m) lead to power the transmitter from a vehicle. Note,this is not a charge lead. If it is intended to apply the transmitter to a target line at high out levels and long periods,it may be useful to power the transmitter using the 12V DC vehicle power lead.To power the transmitter from the 12V DC vehicle power lead,connect the lead to the 12V DC input positioned on the side of the transmitter.Plug the cigarette lighter plug into the vehicle cigarette lighter socket(be sure that the socket is live,some vehicles only acticate the cigarette lighter when the vehicle is running). It is not necessary to disconnect or remove the standard batteries as the unit will automatically select the external 12V DC supply
Loc-10TX outdoor power Supply(optional)
	12V DC,30ft(10m) lead to power(not charge lead) the transmitter from the mains supply. Note, this is not a charge lead.
LPC Separation Filter(optional)
	The LPC separation filter(LPC) is used to safely inject a trace tone to a live cable via a domestic mains socket, so that the cable can be traced from the premises to the connection in the street,it it suitable for connecting to voltages between 100V AC and 250V AC.
Receiver Vehicle Charging Lead(optional)
	12ft(4m) long lead to charge the receiver’s battery (lithium-ion) while on the move. It is preferable to connect the charge to a cigarette lighter socket that is permanently live. However, do not leave connected to the receiver for excessively long periods
Sonde(optional)
	D38-33-AA 1.5in(38mm )× 4.1in(105mm)long, 9.8kHz, range 16.3ft(5m). 1×AA battery. D38-09-AA 1.5in(38mm )× 4.1in(105mm)long, 83kHz, range 16.3ft(5m). 1×AA battery
	D64-33-LR61 2.5in(64mm )× 7.3in(186mm)long, 9.8kHz, range 26ft(8m). 1×LR61 battery. D64-09-LR61 2.5in(64mm )× 7.3in(186mm)long, 83kHz, range 26ft(8m). 1×LR61 battery.
Clamp (optional)
	VX2/50 Dia.2in(50mm）、 VX4/100 Dia.4in(100mm）、 VX5/125 Dia.5in(125mm）、VX18/450F 18in flexible (circumference 450mm) An accessory used to apply the transmitter signal to an insulated line,removing the need to connect the transmitter signal directly to a conductor or cable sheath
Lithium-ion rechargeable battery pack(standard)
	The lithium rechargeable battery pack is supplied as stadard.Use the battery charge listed below to charge pack.charging is done with the battery inside the receiver.
Receiver battery charger(standard)
	The receiver lithium battery charger is supplied as a standard item,it is powered from the mains supply(100-250V AC)
USB cable(standard)
	The USB cable is used to connect the receiver to a host computer so that software updates can be implemented and also for the transfer of data logs from the unit to a computer.
Alkaline Battery Holder(standard)
	This battery pack is supplied as standard and is used in the event the rechargeable battery pack has fully discharge.it can be considered ad a backup battery pack. It requires six xAA alkaline batteries.
Ground stake(standard)
	Used to make an independent connection to the ground to complete the circuit when the transmitter is connected to a line using the direct connection method.
Direct Connection Lead(standard)
	Used to connect the transmitter to a line using the direct connection method.
Loc-1Tx Alkaline Battery Tray(standard)
