General description
The LT17A is designed for the HVAC/R techni-
cian. The LT17A meter measures current, resist-
ance, voltage, capacitance, frequency, continuity,
and temperature. Test leads store within the meter
and can connect the LT17A to Fieldpiece accesso-
ry heads. The body is made out of durable ABS
plastic and comes with a bright blue backlight for
poorly lit test areas. Get great accuracy with the k-
type thermocouple and easily accessible temp. pot.
User maintenance
Battery Replacement: When the multimeter dis-
plays the " " the battery must be replaced to
maintain proper operation. To prevent electrical
shock, turn off the meter and disconnect leads
before removing the back cover.
Fuse Replacement: When only certain ranges
quit working, check the fuse. Open the case and
replace according to the Overload Protection chart.
All other repairs must be performed by a
Fieldpiece service center.

For your safety...
General: Inspect the test leads for damage to the
insulation or exposed metal. Replace if suspect. Never
ground yourself when taking electrical measurements.
Do not touch exposed metal pipes, outlets, fixtures,
etc., which might be at ground potential. Keep your
body isolated from ground by using dry clothing, rubber
shoes, rubber mats, or any approved insulating materi-
al. When disconnecting from a circuit, disconnect the
"RED" lead first, then the common lead. Work with oth-
ers. Use one hand for testing. Turn off power to the cir-
cuit under test before cutting, unsoldering, or breaking
the circuit. Keep your fingers on the plastic and behind
the ridge of the probes.
All Voltage Tests: All voltage ranges will with-
stand up to 600VAC or 600VDC. Do not apply more
than 600VDC or 600VAC.
AC Tests: Disconnect the meter from the circuit
before turning any inductor off, including motors,
transformers, and solenoids. Hi voltage transients
can damage the meter beyond repair. Do not use
during electrical storms.
Safety: Designed to meet IEC 61010-1
(EN61010-1), CATIII 600V, Class II, pollution deg.2,
indoor use and complies with CE. C-Tick certified.

Field Calibration
(temp offset pot)
The LT17A can be easily calibrated on the job.
Use a bucket of ice water to have a known 32°F
(0°C) temperature. With the thermocouple in the ice
water, adjust the TEMP OFFSET pot on the face of
the meter until it reads 32.0 (0.0).
MAX/MIN
Record the minimum or maximum reading during
a measurement. To exit the MIN/MAX function, hold
the button for more than 2 seconds.
Backlight
Always be very careful when testing in the dark.
You should always have a separate light on the
area you are testing. The backlight will shine for 4.5
minutes when the backlight button is pressed.
