This manual ranger covers the parameters and ranges you need for most HVACR applications. The LT17A meter measures current, resistance, voltage, capacitance, frequency, continuity, and temperature. Test leads store in the meter body and, with the probe tips removed, connect to any Fieldpiece accessory head. The body is made out of durable ABS plastic and comes with a bright blue backlight for poorly lit test areas. Get great accuracy using the included k-type thermocouple and an easily accessible temperature calibration pot. The testing capabilities packed into this classic style meter is its main competitive advantage. In addition to all of the ranges, it has direct temperature measurement and works with all of our accessory heads to make it one of the most complete classic style meters available for HVACR professionals.
