● Read this manual carefully before you use it.

● Pls check the power supply accessories good or not before you connect the power,and check

other relative accessories carefully.

● Meet the work conditions as below:

1.Temperature ：-20℃~65℃

2.Humidity ：30%~90%

3.Voltage: DC 12V /2A

● Don't use the tester where the humidity is high.Once the tester is damp,power off immediately,

pls move away other cables connected.

● To prevent the functional decline or failure, the item should not be sprinkled or damped.

● The exposed part of the tester should not be touched by the dust and liquid.

the tester should be powered off from the electric source at once. The test should not be

charged over 8 hours.

● The tester should not be used in the environment with the flammable gas.

● Do not disassembly the instrument since no component inside can be repaired by the user. If

the disassembly is necessary indeed, please contact with the technician of our company.

● The instrument should not be used under the environment with strong electromagnetic

interference.

● Don't touch the tester with wet hands or waterish things.

● Don't use the detergent to clean and the dry cloth is suggested to use. If the dirt is not easy to

tweaked sufficiently.

1.2 Notice of Digital Multimeter :

◆ Do not exceed the specific scale in case there is a breakdown.

◆ For your safety and to prevent electronic shock when test at above DC60V & AC40V.

◆ After make accurate gear option, then begin to test by inserting meter probe.

◆ Allowed not to insert meter probe before make gear option.

◆ Allowed not to test voltage at gear options of Resistance,Diode and contiunity.

◆ Allowed not to test Resistance,Diode and contiunity at gear option of voltage.

◆ Take out meter probe and leave the test point to change next test.

◆ Back to main mode as test different gear options with finding errors displayed on the screen

● Video Level testing, video signals measured in IRE or Mv.

● DC12V 1A power output for camera.

● Audio input testing .

● Digital multimeter, voltage, current, resistance and capacitance can be tested, continuity

testing, diode testing.

● PTZ control. Pan/tilts the P/T unit, zooms in/out the lens, adjusts the focus, aperture and sets

and calls the preset position.

● PTZ continuing rotate test.

● Video displaying. Automatically adapts and displays the video format of NTSC/PAL.

● LCD Brightness/Contrast/Color Saturation is adjustable.

● Video Generating, The PAL/NTSC multi-system color bar video generator (seven-system

switchable, transmit/receive seven-system colorful imagines) .

● Data analyst. Captures and analyzes RS485 controlling data to help the technician to find out

the problem.

● Cable testing. It is powerful in testing LAN cable, measuring the connecting status, displaying

the sequence of connection and the NO. Of the LAN cable.

● Multi-interface and Multi-baud rate. Support RS232 ,RS485 and RS422 interface; baud rate

ranging from 150, 600 to 19200bps.

● Multi-protocol.Supports more than twenty PTZ protocols.For example,PELCO-P,PELCO-D,

SAMSUNG etc.

● PTZ address scanning, search up the ID of PTZ camera.

● Lithium Ion Polymer Battery(3.7V DC3000mAh).The device employs advanced power control

and protection circuit. The device is high power-efficient, energy saving and environmental

protection. It can last 12 hours for normal use after charging for 4 hours.
