The HDTSMM is a handheld field instrument and does not require installation in a fixed system. HVAC technicians and refrigeration service professionals should follow safe system isolation procedures before connecting any test equipment to live refrigerant circuits or electrical components. Always power down or isolate the relevant system section per manufacturer and local code requirements before taking readings. Handle the touchscreen with care to avoid damage to the display surface.
