Chapter 1 Unpacking and Installation
This chapter describes some inspections that must be performed after you receive the instrument,
and the conditions that you must understand and have before installing and using the instrument.
1.1 To Inspect the package
After unpacking, you should first check whether the instrument is damaged due to transportation.
We do not recommend that you power on the instrument when the exterior is damaged. Then
confirm according to the following packing list.
TH8601 Cable/Harness Tester ×1
Power cord ×1
Instruction Manual ×1
Automatically find point probe ×1
Adapter Fixture 64 channels with 2 and 128 channels with 4
If there is any discrepancy, please contact our company or the dealer as soon as possible.
1.2 Power connection
Power supply voltage range: 100～242 Vac.
Power supply frequency range: 47 ~ 63 Hz.
Power supply range: not less than 100 VA.
The power input phase cable L, neutral cable N, and ground cable E should be the same as the
power plug of the instrument.
This instrument has been carefully designed to reduce the noise interference caused by the AC
power input, but it should still be used in a low-noise environment. If it is unavoidable, please install
a power filter.
Warning: In order to prevent leakage of electricity from causing damage to the instrument or people,
the user must ensure that the ground cable of the power supply is reliably connected to the ground.
1.3 Fuse
The instrument has been equipped with a fuse when leaving the factory, and the user should use the
fuse provided by our company.
Warning: Before powering on, pay attention to whether your fuse position is consistent with the
supply voltage range
TH8601 Operation Manual

1.4 Environment
1) Please do not operate the instrument in the place that is vibrative, dusty, under direct sunlight
or where there is corrosive air.
2) The normal working temperature is 0℃～40℃, relative humidity ≤75%, so the instrument
should be used under above condition to guarantee the accuracy.
3) There is heat abstractor on the rear panel to avoid the inner temperature rising. In order to keep
good airiness, please don’t obstruct the left and right airiness holes to make the instrument
maintain the accuracy.
4) Although the instrument has been specially designed for reducing the noise caused by ac power,
a place with low noise is still recommended. If this cannot be arranged, please make sure to use
power filter for the instrument.
5) Please store the instrument in the place where temperature is between 5℃and 40℃, humidity
is less than 85%RH. If the instrument will not be put in use for a time, please have it properly
packed with its original box or a similar box for storing.
6) The instrument, especially the test cable should be far from strong electro-magnetic field, to
avoid the jamming on measurement.
1.5 Use of Test Fixture
Please use the test fixture or test cable provided by our company. The test fixture or test cable made
by the user or other companies may cause incorrect measurement results.
Precautions:
The shorter the patch cord, the better
Too long external wiring burdens additional flux, which can easily cause false detections for
on-resistance specification testing or short-circuit terminal judgment.
Change the adapter frequently
After the adapter has been used for a long time, the conduction will be unstable when in contact, and
it will cause a false test when testing the low conduction impedance specification; therefore, when
the same good cable is tested multiple times, the poor conduction impedance or intermittence open
-circuit will occure , the adapter needs to be replaced.
Keep jigs and adapters clean
After the machine has been used for a long time, there will be some dust in the fixture. When it is
rainy or the air humidity is high, it will produce poor insulation , which will result in misjudgment
of the insulation resistance specification test.
1.6 Warm-up
1) To guarantee the accurate measurement, the warm-up time is no less than 15min.
2) Please not turn on or off instrument frequently, in order to avoid the inner data fluster.

3.3.2 < OS>
Used to set OS related test conditions, as shown in the figure below: OS Setup page.
Figure 3.3-2
OS Standard (Os Std.)
Set the threshold for judging OS; the threshold range is 1kΩ～50kΩ.
It is used to judge whether the double-sided cable is a path or an open-circuit.
For example, OS standard: set to 2k
If the resistance between the two ends of the cable is greater than 2k, then it means an open circuit
If the resistance between the two ends of the cable is less than 2k, it means a path or a short circuit.
Distributed Capacitance Sensitivity (Cx Std.)
Set the single-side capacitance value; either manually input or obtain the capacitance value by
learning standard parts, the setting range is 0.1pF～9.9999nF.
Whether the single-side cable is open or not is judged by measuring the size of its distributed
capacitance. The distributed capacitance of the single-side cable is the unilateral sensitivity.
For example, unilateral sensitivity: set to 100pF
If the unilateral sensitivity of the cable is greater than 100pF, it means that there is no open circuit in
the cable.
If the unilateral sensitivity of the cable is less than 100pF, it means that the cable has an open circuit.
Side Judgment (Side jdg.)
OFF: Turn off the side judgment function.
ON: Turn on the side judgment function.
Side: enable the side judgment function, and short-circuit the slot judgment.
What is judgment by slot division, let's illustrate with examples:
Assuming a short circuit, there are 4 possibilities, namely:
A1-A2, A1-B2, A2-B1, B1-B2
Since a short circuit cannot occur between A slot and B slot, we reduce the short circuit point to the
TH8601 Operation Manual
11
inside ofA slot and B slot. So 4 possibilities have become 2 possibilities, namely: A1-A2, B1-B2
Then test the conductance of A1-A2 and B1-B2 respectively, and the smaller one is the short-circuit
point.
ExcludingA1-B2, the screening behavior ofA2-B1 is the edge separation function.
%: Turn on the side judgment function and judge the position of the break point, expressed in %.
For example:
The result of the test is 50%, which means that the break point is in the middle of the cable.
Capacitance Speed (C.T.Spd)
Slow
Med
Fast
Set the sweeping test speed of unilateral sensitivity. The slower the speed, the higher the test
accuracy.
For example:
The length of a cable under test is only 5cm, and its unilateral sensitivity is very small, only about
5pF. In order to ensure the accuracy of the test, the test speed is set to slow, and the test stability
reaches 1pF, which meets the test requirements.
Interval OS Time (IOS Time)
Set the interval open and short circuit test time, the setting range is 0～999.9S.
If it is 0 seconds, it means unlimited time, and the test will not be terminated until the tested product
is removed or the STOP button is pressed.
Interval Short Time (IOP Time)
Set the interval short -circuit test time, the setting range is 0～999.9S.
If it is 0 seconds, it means unlimited time, and the test will not be terminated until the tested product
is removed or the STOP button is pressed.
Hull Pin (Hull Pin)
The pins connected to the hull, can be manually inputted or the points can be found through the test
leads.
In addition, the hull pin is used for trigger testing.
For some DUTs of connector type, if you want to automatically trigger the test, it is not feasible to
rely on the traditional unilateral sensitivity to judge, because the unilateral sensitivity of the DUT is
often less than 1pF and cannot be accurately measured.
Therefore, connect its hull to the test port, when the operator takes the tested part and inserts it into
the jig for testing, the instrument will scan a distributed capacitance brought by the human body, this
capacitance can be accurately measured, so as to achieve the purpose of automatically triggering the
test.

Whether there is a large capacitance between the lines, and use the large capacitance as the dividing
point to divide the network table.
OS Speed (OS Speed)
When sweeping the cable loop, how much to delay, then read back the level. The size of this
parameter depends on the size of the capacitance between the lines, the larger the capacitance, the

longer the delay. The default is 0us.
Sweeping Method (OS Meth)
Dich.
One
Dichotomy, fewer scans, high speed, its number of times is log2(N), where N is the total number of
pins, for example, a 64Pin cable requires 6 times.This method is suitable for pure thread products
One corresponds to the other
Sweep each pin one by one, its number of times is N, in other words, N pins need to sweep N times.
Although this method is much slower than the dichotomy, it is suitable for products with passive
components.
Fast Interval Open-Circuit (IO Speed)
The fast mode of interval open-circuit, normal interval open-circuit can only detect 4ms width
interval open-circuit.
But when the fast interval open-circuit is turned on, the interval open-circuit with a width of 5us can
be detected.
Note: fast interval open-circuit also requires special tooling to match it before it can be used.
After Fail (Aft Fail)
Empty
Short
Open
Repeat
When the trigger mode is automatic, when a OS circuit is tested, if a fault occurs, under what
conditions need to end the test and report the OS circuit failure.
Empty spot stop: When the test piece is removed, that is, the sweeping end shows an empty network
state, and the instrument ends the test.
Short-circuit stop: When a short-circuit failure occurs, the instrument ends the test.
Open circuit stop: When a open-circuit failure occurs, the instrument ends the test.
Repeat stop: When the same bad condition occurs N times (N can be set), the instrument ends the
test.
Negative Timer (NG Timer)
As mentioned above, negative repeated N times, the instrument ends the test, this N times is to set
here.
Rigid OS
In traditional OS circuit, a resistance of Nk (the value range of N is 1~50) is used as the dividing
line, <Nk is short-circuit, and >Nk is open-circuit.
This kind of rough division method has poor accuracy and often cannot describe the accurate
network structure of the DUT.
Therefore, after the traditional OS circuit sweeping, the conductance sweeping is added to further
analyze the network structure.
If it is set to 10 ohms here, then it will be considered as a short circuit based on the sweeping
resistance value <10, and >10 judged as open circuit.

3.3.3 Conduction
Used to set the relevant test conditions for conduction, as shown in the figure:
Figure 3.3-3 Conduction Page
High Limit (Hi. Lmt.)
Set the high limit of the conductance value, the setting range is 0 Ω ~ 2000 Ω.
The high limit of the specification used to judge whether the conductance is qualified.
You can directly input or connect to the tested sample through the numeric keyboard to learn and
obtain a measured value as a reference value.
Low Limit (Lo.Lmt.)
Set the low limit of the conductance value, the setting range is 0Ω ~ 2000Ω.
The low limit of the specification used to judge whether the conductance is qualified.
You can directly input or connect to the tested sample through the numeric keyboard to learn and
obtain a measured value as a reference value.
Interval Specifications (Int. Spec)
Set the high limit of the change value of the interval conductance test.
The high specification limit used to judge whether the interval conductance resistance is qualified.
You can directly input through the numeric keyboard or directly copy the high conductance limit
above.
For example, the conductance resistance value of A1-B1 is 0.985 ohms
Then in the interval conductance test, A1-B1 was tested N times, N conductance values are
generated, then change value = maximum value-minimum value, If the change value> this interval
specification value, then judged as negative.
Interval Time (Int. Time)
Set the time to measure the interval conductance resistance, the setting range is from 0.1s to 999.9s.
It cannot be set to 0s, and unlimited time testing is not supported.

accuracy.
For example:
A certain cable under test, the cable length is only 5cm, its conductance resistance is very small,
only about 5mΩ.To ensure the accuracy of the test, the test speed is set to slow, and the test stability
is up to 1mΩ, which meets the test requirements.
Interval Fail (Int. Fail)
Stop
Cont.
What to do when the interval conductance test is negative: whether to stop the test and report FAIL
immediately or complete the test and report FAIL later.
Error Loop (C.F.C.T.)
OFF
ON
When error loop is turned on, when the conductance test is failed, the instrument will cyclically test
the conductance resistance value of this pin, and displayed on the test page, the test can be
continued until the test passes. You can also press the STOP button to stop the test, and the
instrument will directly report the FAIL result.
Test Current (DC Curr.)
Standard
The test current of the conductance resistance can be set from 1mA to 20mA, if the standard is
selected, it is 20mA.
Conductance Network (Co Nets)
Normal
Stars
A - B
Mix
The pin combination mode of conductance resistance:
Normal: Conduct the conductance test on two adjacent short-circuit pins, for example: a certain
network is: A1-A2-A3-B1, then you need to test 3 groups of conductance resistance, which are:
A1-A2
A2-A3
A3-B1
Stars: First, we must set a common pin, then combine with other pins to form test pins.
For example, setA1 as a common pin, then the conductance resistance test pin combinations are:
A1-A2
A1-A3
A1-B1
A - B: The pins of different sockets match each other, and then the conductance pin will become:
A1-B1
A2-B1
