The 4445 Voltage Detector Tester provides the most convenient and reliable means of verifying operation of Salisbury Voltage Detectors. The tester features instant push-button operation and requires a standard 9-volt battery (included). It’s portable and lightweight. To operate, push the button and move the tester toward the voltage detector being verified. The tester generates an electric field that activates the detector verifying the audible and visual signals are operational. instructions 1. Switch the Voltage Detector on and to the voltage setting intended for use on the power line. 2. Hold both the 4445 and the Voltage Detector as shown here, but far enough apart that the Voltage Detector shouldn’t be activated when the 4445 is initially switched on. Orient the devices such that the Voltage Detector is at the same angle to the ground as it will be when used on the power source (this may expose some gravity influenced faults such as poor battery contacts). 3. Switch on the 4445 by depressing the pushbutton, and gradually reduce the distance between the two devices until the Voltage Detector first indicates that it senses the 4445’s electric field. When the electric field is first detected, note the distance between the two devices (the activation distance) and compare it with the normal range expected. An activation distance outside the normal range suggests that the Voltage Detector may be faulty and should not be used. (Note that the user must determine from experience what is a normal activation distance for each voltage setting of a particular model Voltage Detector. Voltage Detectors will respond differently depending on the make and model. Furthermore, because the two devices are capacitively coupled with the user providing the electrical return path, the air gap between the instruments must be kept well clear of obstructions or interfering bodies such as the operator’s arms, to avoid affecting the activation distance.) 4. If the Voltage Detector has tested satisfactorily, use it to check the power line as recommended by the Voltage Detector manufacturer. 5. Retest the Voltage Detector as in the previous steps to ensure that the device is still operating normally. If the Voltage Detector fails the retest, both it and the results of the power line test must be considered suspect. TROUBLE SHOOTING

CHECKING THE 4445 Although the 4445 is an extremely reliable electronic device, it is prudent to carry out annual checks of its operation (more frequently if subjected to harsh conditions). There are several options for testing depending on the availability of test equipment. They are as follows: l The high pitched whistle generated by the 4445 (about 10 kHz) is generally a good indicator that the device is functioning normally. The tone is caused by vibrations in the output transformer and verifies that the batteries are healthy and that the output transformer is being triggered. Whilst not a definitive test, it provides a simple method that allows the operator to check the device each time it is used. It should be noted that operators with high frequency hearing loss may not be able to take advantage of this easy technique. l By pairing each 4445 with a dedicated voltage detector, the two devices can provide a means of checking each other. The ability of the 4445 to trigger its paired voltage detector at a similar activation distance each time indicates that both devices are functioning normally. Each 4445 should be submitted to an annual bench check with its partner and the results recorded. The subsequent historical record can be used to reveal any changes in performance. l More elaborate testing could be conducted by setting up a capacitive plate at each end of the 4445 and using a digital voltmeter or an oscilloscope to measure the AC voltage between the plates when burdened with a 100kΩ load. An historical record can again be used to reveal any changes in performance.

If the AC field is not sensed or only weakly sensed by the Voltage Detector, several possibilities exist. Either of the two devices may have failed or have weak or incorrectly installed batteries. In any case, the failure of the Voltage Detector to properly detect a field renders it unsuitable for live use until it has been retested and found to be operating correctly. After ruling out battery problems, both devices should be tested independently to determine which has failed. If the AC field is detected at a larger activation distance than normal, then the voltage detector should also not be used. Both devices should be tested independently to determine the cause of the apparent increased sensitivity.

note: The 4445 is powered by one 9V dry cell. The device is polarity protected and will not be damaged by an incorrectly inserted battery even though it won’t operate in this situation. An alkaline battery may last for up to 11 hours of continuous use. In many cases, battery life will be similar to shelf life. disclaimer: Users should always first check with the voltage detector’s manufacturer or supplier as to whether the 4445 is compatible with the particular voltage detector they are using. Voltage detectors by their nature are generally not precise measuring instruments – accordingly any tester can only be used as a guide to the voltage detector’s correct operation.
