The Fieldpiece LT17A Digital Multimeter 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 are stored in the meter body and, with the probe tips removed, connect to any Fieldpiece accessory head. The body is 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.

Its main competitive advantage is the testing capabilities packed into this classic style meter. In addition to all ranges, it has direct temperature measurements. It works with all of our accessory heads to make it one of the complete classic style meters available for HVACR professionals.

Fieldpiece LT17A Digital Multimeter can measure Temperature and Alternating Current/Direct Current Voltage & Current, Frequency, Capacitance, Resistance, Temperature, and Diode Testing. Changeable test leads mean you can change the heads, and the ABS plastic case is highly durable. This meter has a bright backlight and a k-type thermocouple.

Some of the nice features of this Fieldpiece multimeter is it has a continuity indicator.  It also offers silicone leads with detachable probe tips. And lastly, it has an auto power-off (APO) to conserve battery life.
