3 HILT 9000 - Inductive Loop Tester General Description The HILT -9000 is designed to measure characteristics of an inductive loop at dif ferent frequencies; measure working parameters of the loop system; as well as simulate the detector by measuring the change of inductance. The measurement modes can be easily switched by pressing corresponding bu[...]

4 www.atsi-tester .com Overview of HIL T 9000 Contr ols 1. LOOP: Measures R DC , L, and Q . If Q >15, use Q push- button to obtain actual value. 2. Q : Measures high Q values (when Q is >15). 3. Used in SET FREQ mode to increase frequency by 1KHz. 4. Used in SET FREQ mode to decrease frequency by 1KHz. 5. POWER: Tur ns unit On/Off. 6. SET FRE[...]

5 HILT 9000 - Inductive Loop Tester Function Controls Power Press the POWER push-button to tur n the tester on and off. The tester per for ms an initial self-test to verify that the inter nal circuit is working. After the self-test is complete, the tester shows the current battery level and the message: Ready: Select Function . If the battery is lo[...]

6 www.atsi-tester .com The LOOP test can measure a maxi- mum Q of 15. If Q is greater than 15 the tester displays Q >15 . To measur e the actual value, press the Q button on the keypad to run a separate Q test. The default frequency at which the LOOP and Q tests run is 50 KHz. It can be changed to any value within the range from 20 KHz to 80 KHz[...]

7 HILT 9000 - Inductive Loop Tester , , Set Frequency When the tester is powered, the test frequency is automatically set to 50 KHz. The frequency can be changed to any value between 20 KHz and 80 KHz with 1 KHz resolution. T o set a dif ferent fr equency press the SET FREQ push-button to view the fre- quency adjustment display as show in Figure 5.[...]

8 www.atsi-tester .com If there is bad connection, the tester displays a message as shown in Figure 7. Make sure that the test leads are properly connected. If the leads are connected to the loop and the message is still present, it means that Q of the loop is too low to generate the oscilla- tion or the inductance is out of range. This can be veri[...]

10 www.atsi-tester .com Overview of T raf fic Loop Detection Systems The inductive loop represents the most commonly used method to detect vehicles. The inductive loop is simply a coil of wires embedded into the pavement and can be characterized by several parameters, L (inductance), Q (quality factor), R (active resis- tance, measured using AC sig[...]

11 HILT 9000 - Inductive Loop Tester To guarantee a reliable oscillation in the loop system the quality factor ( Q ) of the loop with the lead-in wires should be above some value, deter mined by the amplifiers inside the detector . Deterio- ration of the loop and lead-in wires reduces Q and eventually prevents the system from oscillating even with [...]

12 www.atsi-tester .com Commonly Asked Questions Q . Why do I have to disconnect the detector from the loop before running a Loop , Q , or ∆ ∆ ∆ ∆ ∆ L test? A. During Loop, Q , and ∆ L test, the tester is applying its own signal to the loop. The tester verifies there is no signal on the loop before running these tests. However , with a [...]
