POE mode: Used to search cable with load on a POE switch
High power mode: the maximum detection range can be up to 0.5 meters. When the cable is very long or the buried line is buried deeply, which cannot be detected by ordinary line finder, high power mode can be used

Does 8601S need to be calibrated when measuring the length?The 8601S adopts TDR principle to measure the length, with high measurement accuracy and no calibration.
Considering the needs of individual users, 8601S does not turn off the user calibration function in the design, but the calibration requirements are high, and the line above 50 meters should be used as the benchmark (other products of our company generally use the line above 10 meters to calibrate)

Which model of 8601 series can measure the length of 4+2 network cable and 8+2 network cable? Which model to choose?8601S can measure the length of 4+2 network cable and 8+2 network cable, but neither 8601 nor 8601W can.
If you are measuring the length of 4 /8 signal lines, you can use network cable mode
If you are measuring the length of the two power cords, it is recommended to use a custom mode

Can 8601S measure the length of wire and cable? What should I pay attention to8601S can measure the length of multi-core wire and cable, but can not measure the length of single core cable. That is to say, the cable should be more than 2 cores. When measuring, use alligator clip to clamp two lines respectively, select custom mode.

What is the error of measuring cable breakpoint of 8601S?The error for 100 meters is about 5 meters, and for 600 meters it's 3%

How long does 8601S need to be fully chargedabout 2-3 hours

8601S unit alignment line is not correct? How accurate is the measurement of length?It is necessary to use the remote adapter for the cable, and there will be errors in measuring the length. You can first use a cable of more than 5 meters for calibration, and then re-test the length.

How does 601S align? Looked for a line on the switch and rang everywhereUse remote alignment; If there is signal interference, the sensitivity can be lowered to test the cable

8601S charging can be turned on, unplug the line can not open the machineIt is recommended to charge it for 2 to 3 hours before trying.

8601S how to turn on cable test mode?Press SET, and the cable test light will come on.

Why does the 8601S sound when the line is not the target line when it is testing?There is signal interference, the sensitivity can be lowered to achieve a more accurate tracking。

The 868 remote test line has an open circuit, why I cut the 2 core wire, and the displayed result is that both the 1 core and the 2 core are open?The display of 868 pairs of lines is a pair display, which can be judged as the existence of an open circuit of 1 core or 2 cores, or the existence of an open circuit of 1 core and 2 cores at the same time. The display mode is normal, and the instrument has no problem
