Fourth, continuous measurement
CAUTION: To avoid electrical shock, do not perform measurements when voltage is applied to the object under test.
1. Slide the function key to the))) position
2. Insert the black test lead into the negative COM and the red test lead into the positive Ω jack
3. Press the MODE key, and the symbol ()) appears on the display
4. Connect the test leads to the wires to be tested
5. When the resistance is less than 150Ω, the instrument will give an alarm, if the measured object is open, the screen will display 'OL'

Fifth, the diode test
1. Slide the function key to the))) position
2. Press the MODE key to select the diode mode
3. Connect the probe of the test lead to the diode under test
4. The screen displays: the voltage should be 0.400-0.700V, if the short circuit, the display voltage close to 0V; the case of open, the poles will show the 'OL'

6, 10Base-T cable measurement
1. Insert a section of the cable under test into the RJ45 jack of the switch, and the other end of the 'back' cable will be shown on the RJ45 jack of the receiver
2. When the switch is turned on and the meter is set to automatic status, the top row of the indicator lights will start to be viewed in sequence, and if it is manual, the PIN1 indicator will glow
3. Press the AUTO / MANUAL key to switch the meter to the desired state
4. When both ends of the cable are plugged in, the second row of lights will light up accordingly
5. If the status of the cable under test can not be read out in the automatic mode, wait for the second time, or switch to the manual mode to read the result of the light display. In the manual mode, press the measurement key to switch to the measurement of the next terminal.
First, the direct / AC voltage measurement
1. Insert the black test leads into the negative COM jacks and the red test leads into the positive V jacks
2. Set the function key to the DC voltage or the AC voltage
3. Connect the test leads to the measured voltage
4. Read out the value displayed on the LCD

Second, the direct / AC current measurement
1. Slide the function key to the uA or mA position
2. Connect the black test lead to the negative COM jack and the red test lead to the positive uA / mA jack
3. When measuring the DC current below 2000uA, slide the function key to the mA position
4. Press the MODE key to display the AC or DC mark
5. Connect the black probe to the negative of the measured current and the red to the positive
6. Turn on the measured current switch
7. Read the value displayed on the display

Third, the resistance measurement
CAUTION: To avoid electrical shock, remove the battery and unplug the power cord before disconnecting the battery.
1. Slide the function key to the Ω position
2. Insert the black test lead into the negative COM, and the red test lead into the positive Ω socket
3. The probe through the test leads through the circuit, the best resistance to the end of the power off, this will ensure that the reading is not subject to interference
4. Read the value displayed on the display
Seven, coaxial cable test
1. Plug the two BNC adapter cables into the two RJ45 jacks and connect the cable under test to the other end of the BNC adapter cable
2. Refer to steps 2 to 5 of the 10Base-T cable measurement for the remaining test procedures
note:
1. The second row of indicators should be able to read the BNC core probe
2. Since the coaxial cable has only two wires, manual status measurement is recommended

8, remote measurement
1. Plug one end of the cable under test into the RJ45 jack and the other end into the remote terminal. If the cable under test is embedded in the dashboard or in the wall, use the dashboard cable to solve the connector problem
2. Slide the AUTO / MANUAL key to the AUTO state for measurement
3. Read the readings of the remote terminal's display
Note: The display lights on the remote terminal display the readings in the order they are connected to the main converter
