1.2. ON by Smart Prox if batteries are Low morse type pulsating sound no light and if during standby everything is OK with the Hardware AND Software Quick Sound followed by Quick Red Flash With the Smart Prox 2 0HP physical contact with electrical conductors is not necessary when testing for live lines Smart Prox works by proximity to AC Its sensor senses the radiated field which surrounds AC live conductors That Sensed signal is filtered digitally by the microprocessor using Digital Signal Processing techniques Only relevant AC signals frequencies are accepted by the microprocessor to alert the user thus decreasing the false alerts from statics or electrical noise Detection distance of a 240Vac single wire is 10cm with a bunched neutral and earth cable as in a flexible cable the distance is reduced to 5cm Checking or proofing the tester is done automatically by the Diagnostic Test Pulses The Smart Prox 270HP has a special circuitry which United States Design Patent US D474 705 S 270HP Designed for Professionals test itself entirely The Diagnostic Circuitry test the following The Sensor plate the wiring from the main PCB to the sensor the wiring from the sensor to the Test Pulse circuit the microprocessor program the Buzzer the Red Light and of course the working of the sensing pulses Once all these are correct and only then Smart Prox report on it s status by using a quick Buzz follow

4. both the buzzer and the Red Light must be ON If one failed the user would know that when the Light or the Buzzer is ON it s that Vac has been detected This is the only case where the buzzer or the light stays ON They are both independent from each other even inside the micro the pins are separates D S P Type Pass Band Filter 40 to 70 Hz Is this to limit the detected voltages to line systems only Yes the 270HP must only detect 50 or 60Hz basically this is because the 275HP would also buzz with static electricity for example when you rub it on your clothes Of course It does not matter if it does that when you rub it on your clothes that was the old accepted method of testing if the product was working in the past But when the head of the 275HP is close to a dead HV cable which is swigging in the air that static also trigger the 275HP not the 2 70HP In some cases the 275HP kept buzzing on dead cables just because of the static generated by the swing on the cable in the air The use of a digital filter make the other products look a bit old by it s ability to differentiate between non AC signal and signals which are not between 40 to 70 Hz Does this improve voltage discrimination where there are dual voltages we have LV cables at 1 level on the pole and then 11kV a few meters higher on the same pole and some times the 11kV signal can confuse someone testing the LV 415V lines would think that it does not where

6. ed by a quick Red flash indicating EVERY THING IS WORKING OK WAITING FOR AC As you can see the indications are also tested and the user can determine that everything is ok The NEW Smart Prox 2 70HP is enclosed into a water tight Nylon flame retardant material enclosure and uses 3 x 1 5V C size batteries some of the typical uses are identify and check live cables find fault in flexible cables check earth equipment service neon lightning trace live wires detect residual or induced voltages For example faults in damaged flexible cables are found by applying low voltage to each conductor Earth the remainder and moving the tester along the cable until the change in condition is obtained Flexible cables which are used in mining and building industries are readily repairable when the break in the cable is located When testing for high voltage the rotary switch attenuator is used to identify and differentiate various HV live cables The tester must be used in conjunction with along and insulating rod when measuring high voltage kV Questions Answers Leds Buzzer Driven independently assume that the buzzer and LEDs are controlled separately by the micro Why is this better There are 2 transistors driven independently from 2 different pins of the micro If one circuit should fail it is unlikely that the other would fail at the same time So the user could still use the tester to detect Vac as when Vac is detected
7. mixed voltages are present the same thing should happen The way to discriminate that is with the sensitivity selector and the distance PRODUCT COMPARISON TABLE Hi Prox 275HP Versus Smart Prox 270HP FUNCTION Hi Prox 275HP Detects Proximity of AC Voltage Voltage Sensitivity Selector User s Manual Sunrise Head Hot Stick Adaptor Built In Nylon Flame Retardant Material 2 Years Warranty 2 High Bright Red Leds S KISIS S 4 High Bright Red Leds High Power High Pitch Buzzer lt Leds Buzzer Driven independently Leds Buzzer Driven Together Pulsing Signal for Low Battery no light Vac Detect Continuous Buzz and Light Permanent Diagnostic and Test Signal Test Signal Position on Selector Battery Voltage Measurement On Line D S P Type Pass Band Filter 40 to 70 Hz Up to 11 Voltages Selection on Request Different Alerting Sounds and Light Water Tight Enclosure Fail Safe Design by Watch Dog Timer Internal Hardware Checked by Test Pulses Maximum Sensitivity if Switch Fails Open 3 x 1 5V D Size Cells for Long Life Standby All OK Quick Buz then Quick Lit Priority Alert System Vac Low Bat OK
8. pass the low battery alert and the everything ok alert The Low battery has priority on the all ok signals Even if everything is ok if a low battery is detected the 2 0HP will buzz pulse morse sound type but still measure Vac etc Fail Safe Design by Watch Dog Timer What does this do If for any reason the software get stopped or if there is a condition which stops the micro it will reset by itself and restart just like an ON OFF switch The watch dog timer keep everything running smoothly if the software does not goes where it should then it will reset the device and start from scratch again Standby All OK Quick Buzz then Quick Lit When I turn the sample ON it just goes straight into the test diagnostic pulse mode Is it supposed to do a full Check first with the LEDs and Buzzer coming ON together for a second or so The tester start working normally after around one to 2 seconds it will goes straight in test diagnostic pulse mode after starting It does a full check all the time unless Vac is detected Priority Alert System Vac Low Bat OK What is this doing same as different alerting sounds and light explanation above Limitations of use It is recommended that the 270HP Is not used in HV yards of mixed voltages In the presence of mixed voltages it could become difficult to determine exactly which source has been detected or which source created the alert Specifications subject to change without notice
