1.1 Product Overview 7 Chapter 1 Overview 1 Overview 1.1 Product Overview 2 The Hioki 3665-20 LAN CABLE HiTESTER is a hand-held cable tester that provides easy operations to test wiremap, measure cable length and identify twisted-pair cables. It is useful for verifying connections after installing connectors on cables. Optional terminators are available to facilitate easy identification of multiple cables.
8 1.1 Product Overview Testing cable connections after installing connectors Checking wiremaps (p.18). Troubleshoot cables in working networks When an open- or short-circuit fault is present in a cable, the HiTester displays the distance along the cable from it to the fault. So when a problem occurs in a working network, the HiTester determines whether the problem is caused by an open- or shortcircuit in the cable, and its location (p.27).
1.2 Features 9 1.2 Features Test cable wiremap, measure length and identify connections with a simple procedure: just connect the ends to the 1 Overview Simple Operation 2 HiTester and a terminator, and press the TEST key. 3 Compact Size 4 The compact HiTester can be carried as a hand tool and operated with one hand.

4.1 Setting an NVP Value Setting Procedure 31 Chapter 4 1 4.1 Setting an NVP Value 2 NVP is the speed of a signal through a cable relative to the speed of light in a vacuum. See "Section Theory of Cable Length Measurement" (p.34) for details. 4 Setting Procedure The optimum NVP value setting depends on the type of cable and twist state of the wire pairs. Cable length measurement accuracy can be optimized by setting the appropriate value for the actual type of cable to be measured.
32 4.1 Setting an NVP Value 4.1.1 Settings for Standard Cable The most accurate cable length measurements are achieved by setting the NVP value to match the actual type of cable to be tested. Before measuring, prepare a standard reference cable using a known length of exactly the same type as that to be tested. Calibrate the HiTester according to the following procedure. We recommend that the standard reference cable be at least 100 m (382 feet) long.
33 4.1 Setting an NVP Value 5. Press the TEST key to measure the cable length. 1 The cable length measurement range of this instrument is 2 to 300 m (6.6 to 984-ft.). 6. Change the NVP value with the S / T keys so that the displayed length matches the measured physical length of the standard reference cable. NVP value 7. 3 4 Setting Procedure (In this example, "100.
34 4.1 Setting an NVP Value Theory of Cable Length Measurement The HiTester employs the TDR (time domain reflectometry) method to measure the amount of time from the input of a pulse to the return of its reflected wave from the far end of the cable.
35 4.1 Setting an NVP Value 4.1.2 Changing the NVP Value Use the following procedure to change the NVP value. 1. 2. With the HiTester turned on, hold the ond to display the Settings screen. SET key for one sec- Select "Length Adjust" with the S / T keys, and press the SET key. 1 2 3 4 Setting Procedure 5 3. 6 Set the NVP value with the S / T keys. 7 (In this example, "0.700" has been selected) 4.
36 4.2 Changing Displayed Measurement Units 4.2 Changing Displayed Measurement Units The measurement units in which the cable length is displayed can be switched between "m" and "ft" by the following procedure. 1. With the HiTester turned on, hold the ond to display the Settings screen. SET key for one sec- 2. Select "Unit" with the S / T keys, and press the 3. Select "m" or "ft" with the S / T keys, and press the key to accept. SET key. SET (In this example, "ft" has been selected) 4.
37 4.3 Switching the Beeper On and Off 4.3 Switching the Beeper On and Off HiTester operating sounds can be set on and off (silent) by the following procedure. 1. 2. With the HiTester turned on, hold the ond to display the Settings screen. SET key for one sec- 1 2 3 Select "Beep" with the S / T keys, and press the key. SET 4 Setting Procedure 5 6 3. Select "ON" or "OFF" with the S / T keys, and press the SET 7 key to accept. 8 (In this example, "Off" has been selected) 9 10 4.
38 4.4 Initializing Settings 4.4 Initializing Settings To initialize HiTester settings by the following procedure. Initialized Settings • NVP value (Initial setting is "0.684") • Beeper (Initial setting is "On") • Measurement Units (Initial setting is "m") 1.

45 Optional Accessories Chapter 6 The following options are available for the 3665-20 LAN CABLE HiTESTER. Ask your dealer or Hioki representative when ordering. Terminators To conveniently identify multiple cables with the HiTester, you can use the optional terminators (sold in 5-piece sets) to eliminate the need to change cable connections at the far end.
46 Model 9249 CARRYING CASE The hard case holds the HiTester, terminators and a LAN patch cable. Extra space is provided for other tools. Keep this manual in the flap pocket inside the cover. Model 9628 LAN CABLE Use this patch cable to connect the HiTester to the cable to be tested through a wall jack (for cable testing, 1 m long, with RJ-45 plugs on each end).
7.1 Cleaning Maintenance and Service 47 Chapter 7 Never modify the instrument. Only Hioki service engineers should disassemble or repair the instrument. Failure to observe these precautions may result in fire, electric shock, or injury. 7.1 Cleaning To clean the instrument, wipe it gently with a soft cloth moistened with water or mild detergent. Never use solvents such as benzene, alcohol, acetone, ether, ketones, thinners or gasoline, as they can deform and discolor the case.
48 7.2 Troubleshooting Troubleshooting Symptom Checks and Remedy Cable length is not displayed Is the cable between 2 and 300 m long? →The cable length measurement range of this instrument is 2 to 300 m (6.6 to 984-ft.). However, cable length cannot be measured if the cable’s characteristic impedance is far from 100 Ω. The Model 9628 LAN CABLE is 1 m long, so it cannot be measured. The results of the cable length test is different from the actual cable length.
7.2 Troubleshooting Symptom 49 Checks and Remedy An incorrect ID number is Is the test cable connected cordisplayed rectly? →When Open or No Shield is displayed because a cable is not connected correctly, an incorrect ID number may be displayed. (Open or No Shield is displayed when a wire is not connected.
50 7.3 Error Display 7.3 Error Display When an error is displayed, confirm the following contents. Message Description and Remedy No Terminator The 9690 TERMINATOR is disconnected. →Connect the 9690 TERMINATOR. Terminator Error A device other than a 9690 TERMINATOR is connected. →Connect a 9690 TERMINATOR. An error exists on all pins. →Check that the cable is connected securely. Memory Error Some data could not be stored or read correctly. →Press the SET key to initialize HiTester settings.
7.4 Replacing the Batteries 51 7.4 Replacing the Batteries Replace batteries if they are weak. • Do not mix old and new batteries, or different types of batteries. Also, be careful to observe battery polarity during installation. Otherwise, poor performance or damage from battery leakage could result. • To avoid the possibility of explosion, do not short circuit, disassemble or incinerate batteries. • Handle and dispose of batteries in accordance with local regulations.
52 7.4 Replacing the Batteries 1. 2. 3. 4. Remove the test cable, if connected. 5. Replace the battery compartment cover. Turn the HiTester off. Remove the battery compartment cover.
