Description
As a proud owner of the rst wireless digital
multimeter, LT17AW, you are well on your way to
eliminating tangled wires. LT17AW will give you
the power to receive measurements wirelessly
from anywhere on the jobsite. For instance, you
can transmit indoor wet bulb measurements
over-the-air while you work at the condenser.
Your LT17AW can receive measurements
wirelessly from any Fieldpiece accessory head
connected to a Fieldpiece wireless transmitter
like ET2W or EH4W.
In addition, your LT17AW can also transmit
wirelessly any measurement range on the dial
to any Fieldpiece wireless receiver, like EH4W,
HG3, or another LT17AW.
Your LT17AW easily syncs with compatible
wireless Fieldpiece transmitters and receivers.
LT17AW has a wide wireless range to cover the
whole jobsite.
Your LT17AW remembers the last meter it was
synced with, so there is no need to constantly
resync the same pairs. Note: this feature is
available when synched to single-link receivers
such as the LT17AW, ET2W, and EH4W.

Safety Information
• Never ground yourself when taking electrical
measurements. Do not touch exposed metal
pipes, outlets, xtures, etc., which might be
at ground potential, while taking measure-
ments. Keep your body isolated from ground
by using dry clothing, rubber shoes, rubber
mats, or any approved insulating material.
• Disconnect the test leads before opening the
case. Inspect the test leads for damage to the
insulation or exposed wire. Replace if suspect.
Keep your ngers behind the nger guards
on the probes while taking measurements.
• When disconnecting from a circuit, disconnect
the “RED” lead rst, then the common “BLACK”
lead. Use one handed testing when possible.
Work with others.
• Turn o power to the circuit under test before
cutting, unsoldering, or breaking the circuit.
• Do not measure resistance (ohms) when circuit
is powered. Isolate load by disconnecting
from circuit.
• Disconnect the meter from the circuit before
turning any inductor o, including motors,
transformers, and solenoids. High voltage
transients can damage the meter beyond

• Do not apply more than rated voltages between
input and ground.
• Isolate capacitors from system and discharge
them safely before testing.
• Temp switch to prevent leaving thermocouple
plugged in while measuring voltage.
All voltage tests: All voltage ranges will with-
stand up to 600V. Do not apply more than
600VDC or AC rms.
Symbols used:
Caution, risk of electric shock
Caution, refer to manual.

WARNINGS
DISCONNECT AND UNPLUG TEST LEADS before opening case.
DO NOT APPLY VOLTAGE greater than 30VAC or 60VDC to the
thermocouple or the jacks when the rotary dial is on °F. (Use
only k-type thermocouples)
REMOVE THE THERMOCOUPLE when taking voltage measurements.
DISCONNECT TEST LEADS when measuring temperature.
DO NOT APPLY VOLTAGE TO THE JACKS when the rotary dial is on
microamps. Even low voltages can cause a current overload and
potentially harm the meter.
Diode Test (
)
Test diodes for proper forward and reversed-biased functions.

Temp. Calibration
For accuracies of ±1°F, calibrate to a known
temperature. A glass of stabilized ice water
is very close to 32°F (0°C) and is usually very
convenient but any known temperature can
be used.

1. Select the 500°F range.
2. Plug thermocouple to be
calibrated into the K-type jack.
4. Stabilize a large cup of ice water.
Stir the ice with the water until
temperature stays at 32°F (0°C).
5. Immerse the thermocouple probe and let it stabilize. Keep stirring
to prevent micro-environments.
6. Use a small screwdriver to adjust calibration pot to the lower left
of the COM port as close to 32°F as you would like.
Battery Replacement
The battery in the LT17AW must be replaced
when the lower left battery icon ( ) is empty.
The LT17AW will display "bAtt" on the LCD
accompanied by a continuous beep. The
meter will turn o in 5 seconds and no further
measurement will be allowed until the battery
is replaced.
