| back 23  Jigsaw |
front 24 All of the following are electrical characteristics that are measured by a simple digital multimeter (DMM) except
| back 24  Power |
front 25 When referring to a digital multimeter (DMM), the acronym NCV stands for
| back 25 Non-contact voltage (NCV) testers are safe, handheld tools that detect AC voltage in cables, sockets, and switches without touching bare conductors. |
front 26 Which feature of an electric meter allows the technician to measure circuit amperage without accessing the circuit’s bare conductors?
| back 26  Clamp-on jaws |
front 27 The type of refrigerant leak detector that utilizes an open flame is the ____________ leak detector.
| back 27  A halide leak detector is a specialized tool used to locate leaks in non-combustible CFC and HCFC refrigerant systems by drawing air through a probe and passing it over a heated copper reactor plate. If refrigerant gas is present, the detector’s blue flame changes to green, indicating a leak as small as 20 ppm. |
front 28 The type of refrigerant leak detector that uses an internal pump to pull in vapor samples is the ____________ leak detector.
| back 28  Electronic While some specialized types (like heated diode or corona discharge) fall under the "electronic" umbrella, they are the ones specifically designed with a small motorized pump or fan to actively draw air across a sensor. |
front 29 The tubing reamer is used to
| back 29  Remove burrs from a section of soft-drawn tubing. |
front 30 Swaging is the process of
| back 30 Expanding the end of a section of soft-drawn tubing |
front 31 Flaring is the process of
| back 31 reating a bell-shaped bevel on the end of a section of soft-drawn tubing. |
front 32 In order to minimize the potential for leaks in a refrigerant piping arrangement, which of the following processes is desirable?
| back 32 Bending |
front 33 The long handles on a pipe wrench are intended to
| back 33  Increase the torque of the wrench |
front 34 Red-handled tin snips are typically used to make
| back 34  Straight and left-turning sheet metal cuts |
front 35 The sheet metal tool that is commonly used to reduce the diameter of a section of round stove pipe is the
| back 35  Crimper |
front 36 Which of the following torches uses both an oxygen and an acetylene regulator?
| back 36  Oxyacetylene torch |
front 37 The air-acetylene torch flame is about
| back 37 4200°F |
front 38 Which of the following gauge manifold hoses is typically larger than the others?
| back 38 Evacuation hose Typically larger to minimize resistance and allow for faster removal of air, moisture, and non-condensable from the system |
front 39 The digital vacuum gauge measures vacuum in which unit?
| back 39  Microns |
front 40 Which of the following tools monitors the amount of refrigerant added to or removed from an HVACR system?
| back 40  Refrigerant charging scale |
front 41 What two functions does a vacuum pump perform?
| back 41  Dehydrating and degassing By lowering the pressure inside a system, the pump allows moisture to boil off into vapor (dehydrating) and removes non-condensable gases like air and nitrogen (degassing). |
front 42 Refrigerant is mechanically removed from an HVACR system using a
| back 42  Refrigerant recovery unit |
