The LT16A is a classic style multimeter with True RMS meter and phase rotation. This manual ranger covers the electrical parameters you need for HVAC/R and, with detachable test leads, works with our accessory heads to test non-electrical parameters too. The LT16A meter measures current, resistance, voltage, capacitance, frequency, continuity and more. Test leads store in the meter body along with the tilt stand and magnetic hanger. The body is constructed of durable ABS plastic and a blue backlight makes the large LCD even more visible. We like to call this the HVAC/R detective’s meter. It’s the meter for technicians that like to search down, figure out and solve electrical mysteries on a system.
The LT16A is a True RMS manual ranging DMM that comes with an amp clamp and includes phase rotation for testing three-phase motors. Use the MIN/MAX function to record highs and lows. The continuity beeper tells you if a circuit is open or closed. Operation of the LT16A is easy. Simply select a range and test to hunt down those electrical culprits.
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.
400A AC
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 LT17A 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
