  • Page 6: Introduction

    Tru Pointe Introduction Introduction The Tru Pointe Refrigerant Leak Detector (Figure 1) is a portable, battery powered instrument designed to pinpoint the location of refrigerant leaks in air conditioning and refrigerant systems, chillers, or cold storage units. The use of heated-diode sensor technology allows the instrument to be quickly responsive to all refrigerants, even when high background levels of refrigerant vapors are present.

  • Page 7: Features

    Tru Pointe Introduction Features • Quickly pinpoints the location of refrigerant leaks • Patented heated-diode sensor that represents the latest advancements in sensor technology • Patented microprocessor-controlled circuitry • High and low-sensitivity modes, push button selectable • Automatic zero and background compensation that allows a leak to be quickly found in contaminated atmospheres with- out requiring manual sensitivity adjustments • Flexible probe 14 inches (356 mm) in length for locating leaks in hard-to-reach areas • One-handed operation • No user calibration required • Long life, DC brushless fan provides positive airflow past sensor resulting in a faster response time • Batteries included...

    Tru Pointe Operation Operation Battery Installation 1. Remove battery cover by pressing down on the battery cover tab, and then sliding the cover off the instrument. See Figure 2. 2. Install two ‘D’ alkaline batteries into the battery compartment, observ- ing the polarity markings that are molded inside of the case.

  • Page 11: Turning The Instrument On / Off

    Tru Pointe Operation Turning the Instrument ON / OFF See Figure 3. The instrument is toggled ON and OFF by pressing the button. When the instrument is first turned ON, observe that the green power on LED will glow, and that the red LED flashes rapidly along with leak rate the audible indicator producing a rapid ticking sound or constant tone.

  • Page 12: Low Battery Indication

    Tru Pointe Operation Low Battery Indication A low-battery condition is indicated when the green LED begins power on to flash. Approximately 20 minutes of operation time remains from the time this LED first begins to flash; after which, the instrument’s operation will gradually become erratic. When a low-battery indication occurs, replace the batteries as described under the previous Section Battery Installation.

  • Page 13: Sensor Failure Indication

    Tru Pointe Operation When the instrument first detects an increase in the refrigerant level, the LED begins flashing and the audible indicator begins ticking leak rate at a faster rate. If movement of the probe is stopped for more than 10 sec- onds, the instrument will self-zero and return to its idle state even though refrigerant is still present. Once the presence of refrigerant has been determined and the instrument allowed to self-zero, moving the probe toward the leak source will once again cause the instrument to respond in a positive manner.

  • Page 14: False Refrigerant Indication

    Tru Pointe Operation False Refrigerant Indication False refrigerant indications are usually caused by abnormal changes in sensor temperature. These temperature changes are typically due to a sud- den change in air flow past the sensor, or the sensor being heated or cooled by an outside source. To avoid false refrigerant indications, DO NOT . . .
  • Page 15 Tru Pointe Operation • Always follow the refrigerant system around in a continuous path so that no areas of potential leaks are missed. If a leak is found, always continue to test the remainder of the system. • At each area checked, the probe shall be moved around the location, at a rate no more than 25 to 50 mm/sec (1 to 2 in./sec), and no more than 5 mm (0.2 inch) from the surface completely around the position. Slower and closer movement of the probe greatly improves the likelihood of finding a leak.

  • Page 16: Maintenance

    Tru Pointe Maintenance Maintenance By following the procedures outlined below, The Tru Pointe will provide many years of trouble-free and dependable operation. Routine Maintenance • Replace the batteries per Section Battery Installation when the green LED begins to flash. power on • Periodically check the instrument’s sensitivity by exposing it to a source of refrigerant gas. DO NOT check sensitivity by cracking open a bottle of refrigerant or Schrader valve and exposing the sensor to a stream of pure refrigerant.

  • Page 17: Sensor Replacement

    Tru Pointe Maintenance Sensor Replacement Over time the sensor will become less responsive to refrigerant gas as it nears the end of its useful life. A sensor’s average life expectancy is ap- proximately 150 hours or 1 year of normal use, but will vary depending on the amount of refrigerant that passes through the sensor. Replace the sensor as follows (see Figure 4): Material Required: • Sensor (refer to Section Replacement Parts) Procedure: 1. Turn OFF instrument. 2. Grasp nose cone of probe assembly and pull probe away from case using a slight twisting motion.
