1 .Safety information
The tester is intended to use in compliance with the local rules of the electrical usage and avoid to
apply at the places which are inapplicable for the use of electrics such as hospital, gas station etc.
To prevent the functional decline or failure, the product should not be sprinkled or damped.
The exposed part of the tester should not be touched by the dust and liquid.
During transportation and use, it is highly recommended to avoid the violent collision and vibration
of the tester, lest damaging components and causing failure.
Don’t leave the tester alone while charging and recharging. If the battery is found severely hot, the
tester should be powered off from the electric source at once. The tester should not be charged over 8
hours.
Don’t use the tester where the humidity is high. Once the tester is damp, power off immediately and
move away other connected cables.
The tester should not be used in the environment with the flammable gas.
Do not disassemble 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 remove,
the soft cloth with water or neutral detergent can be used. But the cloth should be tweaked
sufficiently.
About Digital Multi-meter
Before using, you must select the right input jack, function and range.
Never exceed the protection limit values indicated in specifications for each range of measurement.
When the tester is linked to a measurement circuit, do not touch unused terminals.
Do not measure voltage if the voltage on the terminals exceeds 660V above earth ground.
At the manual range, when the value scale to be measured is unknown beforehand, set the range
selector at the highest position.
Always be careful when working with voltages above 60V DC or 40V AC, keep fingers behind the
probe barriers while measuring.
Page.2.
Never connect the meter with any voltage source while the function switch is in the current,
resistance, capacitance, diode, continuity, otherwise it will damage the meter.
Never perform capacitance measurements unless the capacitor to be measured has been discharged
fully.
Never measure any of resistance, capacitance, diode or continuity measurements on live circuits.
Visual laser sources
When you turn on visual laser sources, please don’t stare at it, or will damage to eyes
When not using it, please turn it off and cover the protective cap .

3. Operation
3.1 Installing the Battery
The tester has built-in lithium ion polymer rechargeable battery. The battery cable inside battery
cabin should be disconnected for safety during transportation!
Prior to the use of the instrument, the battery cables inside the battery cabin should be well
connected.
Pressing the key continuously can power on or off the tester.
Notice:Pls use the original adaptor and connected cable of the device!
When the battery icon is full or the charge indicator turns off automatically, indicate the battery
charging is completed
Notice: When the Charge Indicator turns off, the battery is approximately 90%
charged. The charging time can be extended for about 1 hour and the charging time within 12
hours will not damage the battery.
Notice :Press the key several seconds to restore the default settings when the
instrument works abnormally.
Multi-meter: the red and black multi-meter pen must insert the corresponding port.
Warnings:Instrument communication port is not permitted access circuit voltage over 6V,
otherwise damage the tester.
Warnings:Not allow insert multi-meter pen in the current
terminal to measure voltage
Page.12.
3.2 Instrument connection
3.2.1 IP camera connection
Power an IP camera with an independent power supply, then connect the IP camera to the IPC tester’s
LAN port, if the link indicator of the tester’s LAN port is green and the data indicator flickers, it means
the IP camera and the IPC tester are communicating. If the two indicators don’t flicker, check if the IP
camera is powered on or the network cable is not functioning properly.
Note:1) If the IP camera requires PoE power, then connect the IP camera to the IP tester’sLAN port .
The tester will supply PoE Power for the IP camera. Click on the icon labeled POE to turn the PoE
Power off or on.
2) If use the tester’s menu to turn off the tester’s PoE power supply, the PoE switch and the power
sourcing equipment are allowed to connect to the tester’s PSE port, and the PoE power will be supplied
to the IP camera by the tester’s LAN port. On this condition, the tester cannot receive data from IP
camera, but the computer connected to the PoE switch can receive the data via the the tester.
Warning: Poe switch or PSE power sourcing equipment only can be connected to tester “PSE
