What is It?

The LT17AW Digital Multimeter is loaded with the parameters and ranges you need for HVACR troubleshooting, plus it receives measurements wirelessly from any of the Fieldpiece Accessory Heads when they are connected to the wireless transmitter that's included.  You can now easily measure current, resistance, voltage, capacitance, frequency, continuity, and temperature either directly, or wirelessly from up to 75' away.  

Because of the wireless capability you can connect your amp clamp and completely close the blower door so you get a more accurate amperage reading.  Or you can set up a wet bulb measurement in the attic and get live readings while you're making adjustments at the condenser. 

Features and Benefits

Designed specifically for HVACR field service, the LT17AW combines wireless readings with specific features and benefits that HVACR field service pros need.

Transforms any Fieldpiece Accessory Head into a Wireless Device
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.

Now with the wireless LT17AW all accessory heads can be used either directly through tests leads,     or wirelessly with the ET2W wireless transmitter that's included with your LT17AW.               

Continuity Indicator
If you were doing lab testing, these features would probably drive you crazy.  We’ve heard from more than one HVACR 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.

Temperature  
Take ambient air or refrigeration line temperatures and more with the built-in K-type port and the included ATB1 wrap tab thermocouple. Add a wet sock (saturated tissue or a shoelace to take wet bulb temperatures. The built-in temperature junction offers great temperature compensation for more accurate and faster measurements,

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.

Frequency
Measure from 10Hz to 40kHz using this range with 1 Hz resolution.

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

And More:

• Volts AC.
• Volts DC.
• Resistance (Ohms).
• Diode Test
• Rugged ABS case with rubber boot.
• Even though it’s a classic style meter it still fits naturally in your hand.
• Auto power-off (APO) to conserve battery life.
