Fieldpiece HS36 Expandable Autoranging True RMS Stick Multimeter w/Backlight The HS36 works with all Fieldpiece accessory heads enabling the user to test a wider variety of parameters from a single meter. Auto Ranging: The HS36 is an auto ranging meter and is very accurate. Non-Contact Voltage Indication: The NCV function is sensitive enough to detect 24VAC on thermostats. High Voltage and Continuity Indicators: The Hi-V LED/Beeper for circuits over 30V. The continuity LED and beeper tells you if a circuit is open or closed. Microamps for measuring the flame diode current in a heater control -- Capacitance for motor-start and motor-run capacitors.
