Note: To avoid electric shock, do not measure when the measured object has a voltage.
1. Slide the function key to the position)
2. Insert the black test lead into the negative terminal COM and the red test lead into the positive Ω jack
3. Press the mode key MODE, the display appears on the display)))
4. Connect the probe of the test leads to the wires to be tested
5. When the resistance is less than 150Ω, the instrument will issue an alarm, if the measured object is open, the screen will display 'OL'

Five, 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 leads to the diode under test
4. Screen display: the voltage value should be 0.400- 0.700V; if short circuit, then the display voltage close to 0V; if open, the two poles will show 'OL'

Six, 10Base-T cable measurement
1. Insert a section of the cable under test into the converted RJ45 jack, and the other end of the 'back' cable will be inserted into the RJ45 jack of the receiver
2. Open the switch, the instrument set in the automatic state, the display of a row above the order will start browsing. If it is manual, PIN1 indicator light will light
3. Press the Auto / Manual key to switch the instrument to the desired state
4. When the cable ends are plugged in, the second row of the indicator light will be lit up accordingly
5. Read out the result of the light display, that is, the status of the cable under test. If in the automatic state, can not read the results of the second display light display, please wait for a second visit, or switch to manual state In the manual mode, press the measurement key to switch to the next terminal measurement.
First, the direct / AC voltage measurement
1. Insert the black test lead into the negative COM jack and the red test lead into the positive V jack
2. Adjust the function key to the DC voltage or the position of 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 uA or mA
2. Insert the black test lead into the negative COM jack and the red test lead into the positive uA / mA jack
3. When measuring direct current below 2000uA, slide the function key to the mA position
4. Press the mode key MODE, the AC or DC mark will be displayed on the screen
5. Connect the black probe to the negative pole of the measured current and connect the red to the positive terminal
6. Turn on the measured current switch
7. Read out the value displayed on the display

Third, the resistance measurement
CAUTION: To avoid electric shock, power off the unit under test and remove the capacitor before removing the battery. Remove the battery and unplug the wire.
1. Slide the function key to the Ω position
2. Insert the black test lead into the negative COM, and insert the red test lead into the positive Ω jack
3. The test probe through the test circuit, it is best to be measured at one end of the power cut off, so as to ensure that the reading is not disturbed
4. Read out the value displayed on the display
Seven, coaxial cable test
1. Insert 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. The remaining test steps refer to steps 2 to 5 of the 10Base-T cable measurement
note:
1. The second row of the display should be able to read the BNC core probe
2. Because the coaxial cable has only two wires, it is recommended to use the manual state measurement

Eight, remote measurement
1. Insert 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 wall, you can use the dashboard wires to solve the problem
2. Slide the Auto / Manual key to the automatic state for measurement
3. Read the readings displayed by the remote terminal's indicator
Note: The display on the remote terminal displays the readings in the order in which they are connected to the main converter
