This pulsating DC holiday detector with regulated voltage has a range of 800 to 35,000 volts (V). This range, in a single instrument, makes the APS unique, but it is the revolutionary Safety Switch and more than 15 other improvements that have been impressing holiday detector users the world over.

The Model APS represents the latest in electronics in the industry, with a new design and numerous improvements over previous, similar instruments, while at the same time maintaining the same accessories of those previous designs.

Tinker & Rasor President Mark J. Byerley Snr, explained, “We felt the need to take advantage of newer technologies to give better command and control to the operator. The new instrument boasts many advancements and improvements over instruments currently available in the marketplace, while maintaining previous instrument compatibility and the Tinker & Rasor reputation of quality.”

Among the numerous improvements is a patent pending safety switch, providing greater job-site safety for both the operator and nearby personnel. This easy to use trigger system means that the instrument cannot be left energised while unattended. The instrument is turned on using a push button, while holding the trigger switch. When the operator releases the trigger, the instrument immediately shuts down. Thumb and forefinger are all that are required to control the instrument.

Another of the new features of the Model APS is the range of output voltages the instrument provides. With a full range of 800 to 35,000 V in one instrument, the user of this instrument has in their hand a tool that will cover the widest range of voltages available. Whereas in the past multiple instruments were required to cover the range of specifications of coatings, now one instrument gives complete coverage.

The Model APS provides 800 V to 8,000 V on low setting and 3,500 V to 35,000 V on high setting. Once the voltage setting has been set, the instrument locks it into memory, no matter how many times the instrument is turned on and off, the setting will remain the same. With the LCD meter display, the user can always be sure of the voltage while the instrument is in use.

The instrument LCD meter display is used to set and monitor output voltages from the instrument. The voltage selector switch and new meter display give the user the ability to set the instrument to any voltage output within its very wide range. Output voltage is regulated and the instrument variance is a very low +/- 5 per cent. The circuitry of the Model APS takes advantage of new technology and components giving greater efficiency and performance from the existing battery.

The instrument is controlled by an electronics package contained within the water impenetrable cover of the instrument. The on, low, high, loud and louder switches are all push-button operation, with large operational areas, easy to manipulate while wearing gloves.

Ergonomically designed with everyone and every size in mind, the angled handle of the Model APS provides users a comfortable grip on the instrument and lessens fatigue while in operation. The open grip design of the handle accommodates different hand sizes of operator with the same comfort level for each, as well as taking into account different types of glove sizes, which may differ depending upon application, climate and other factors.

The Model APS has a “super bright” LED for a visual indication of holiday, in addition to the audible alert. This LED offers thousands of hours of use and can easily be seen during use, even in direct sunlight. The instrument also includes a loud and louder volume setting. This allows users in applications where normal ambient noises exist to use the instrument on loud, while users with significant ambient noise, to use the louder setting. Operators using ear protection should have no problem hearing the alarm on this instrument.

The instrument and accessories are kept in a rugged, water and dust sealed case made of high impact resistant resins. The case is lined with foam and cutouts are provided for each accessory and the instrument, providing superior protection while not in use. The case is lockable, and each case latch has a release button, so the case will not open accidentally. The small edge profile of the case will allow you to find room on the truck laying flat or on its side. Use the padded bar handle when pulling the case on its inline wheels, or the soft grip side handle for carrying. It is also lighter than previous designs, meaning easier handling and lower shipping costs.

The Model APS is sold in kit form, including the instrument, two batteries, battery holder, battery charger, wand handle, ground trail, 4 inch silicone-rubber inspection paddle, screwdriver, instruction manual and carrying case.

Tinker & Rasor has been manufacturing holiday detectors since 1948. The company’s current offerings include four high-voltage and two low-voltage holiday detectors, as well as numerous Cathodic Protection instruments and products, and a complete line of CP Test Stations, Line Markers and accessories.
