DIGITAL MULTIMETER

Model: LT17A

OPERATOR’S MANUAL

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.

rial or workmanship for one years from date of pur-

chase. Fieldpiece will replace or repair the defective

unit, at its option, subject to verification of the
