Designed specifically for HVAC/R field service, the LT16A offers specific features and benefits to HVAC/R field service pros including:

OPEN BOX UNIT, was a customer return, so might have been slightly used.  Comes with full manufactures warranty.   Satisfaction guaranteed or your money back no questions asked
 

• Works with Fieldpiece Accessory Heads 
  There is a Fieldpiece accessory head available for just about any job. There are heads to measure temperature, superheat, subcooling, RH%, wet bulb, dew point, vacuum (microns of mercury), manometer (inches of water column), amps AC&DC, high voltage, CO, %CO2, air velocity, and many more.
• Continuity Indicator 
  If you were doing lab testing, these features would probably drive you crazy. We’ve heard from more than one HVAC/R veteran that these features really remind you of what you’re doing and they’ve avoided potentially dangerous situations in the field. The Hi-V LED and beeper let you know when you’ve hooked up to a circuit over 30V. The continuity LED and beeper tells you if a circuit is open or closed.
• 400AAC 
  Using the detachable test leads and the accessory head amp clamp, read 0-400 amps directly on your meter.
• Capacitance (MFD) 
  Measure microfarads on motor-run and motor-start capacitors using this range. Disconnect the capacitor from power first. Short the terminals to discharge the capacitor. Disconnect any resistors that might be between the terminals of the capacitor and measure to check for degradation.
• Microamps DC - Flame Rectification Tests 
  The most common ‘no heat” call has to do with a malfunctioning flame sensing diode. Simply turn the meter to microamps DC, hook up, and see if the flame sensing rod is functioning properly.
• Phase Rotation 
  Measure the poles of 3-phase motors to make sure it’s spinning in the right direction.
• Frequency 
  Measure from 10Hz to 40kHz using this range with 1 Hz resolution.
• True RMS 
  Digital multimeters use two different types of AC sensing. The most common is average sensing, normalized to a true RMS value of a sine wave. The other is true RMS sensing. The actual true RMS value is sensed for a wave form within the limits of the crest factor. Either sensing method will give the same results on a clean sine wave but they may differ on a non-sinusoidal waveform.
• Silicone Leads with Detachable Probe Tips 
  Because the wire insulation is silicone, the leads stay flexible in cold weather and will not melt if bumped by a soldering iron. When testing electrical circuits with two hands, there is a risk that a careless mistake may complete a circuit through your body and potentially cause death or injury. Use the either probe clip on rubber boot to connect and firmly hold the V lead in place, detach the COM probe tip, connect an alligator lead tip to COM and ground, and perform a one-hand test more easily than most meters on the market. Built-in lead storage makes it easy to keep everything together from job to job.
• Tilt Stand and Magnetic Hanger 
  One thing we hear from technicians every day is how much they enjoy the magnetic hanger because it keeps the meter out of the way while testing. The LT16A includes the magnet and a tilt stand to give you a choice in the way you want to use it.
• Bright Blue Backlight 
  Easily read the display in overcast conditions or in dimly lit areas.
• MAX/MIN hold 
  Record the minimum or maximum reading during a measurement. To exit the MIN/MAX function, hold the button for more than 2 seconds.
• And More:
  • Volts AC.
  • Volts DC.
  • Resistance (Ohms).
  • Diode Test.
  • Rugged ABS case with rubber boot.
  • Fits naturally in your hand despite classic design.
  • Auto power-off (APO) to conserve battery life.
