AUTORANGING POCKET

DIGITAL MULTIMETER: SPDM1

OPERATOR’S MANUAL

For your safety...

General: Inspect the test leads for damage to the
insulation or exposed metal. Do not use if the meter
or test leads look damaged, or if you suspect that the
meter is not operating properly. 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 mate­rial. When disconnecting from a circuit, disconnect
the "RED" lead first, then the common lead. Work
with others. Turn off power to the circuit under test
before cutting, unsoldering, or breaking the circuit.
Keep your fingers behind the finger guards on the
probes. Do not measure resistance when circuit is
powered. Do not apply more than rated voltage
between input and ground.

All voltage tests: All voltage ranges will withstand
up to 600V. 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. High voltage transients
can damage the meter beyond repair. Do not use
during electrical storms.

Maintenance

Clean the exterior with clean dry cloth. Do not use
liquid.

Battery replacement: When the multimeter dis­plays " " the battery must be replaced. Disconnect
leads from test points, turn meter off, and remove the
battery cover. Replace the battery with 2 NEDA #
1166A 1.5V batteries.

Limited warranty

This meter is warranted against defects in materi­al or workmanship for one year from date of pur­chase. Fieldpiece will replace or repair the defective
unit, at its option, subject to verification of the defect.

This warranty does not apply to defects resulting
from abuse, neglect, accident, unauthorized repair,
alteration, or unreasonable use of the instrument.

Any implied warranties arising from the sale of a
Fieldpiece product, including but not limited to
implied warranties of merchantability and fitness for a
particular purpose, are limited to the above.
Fieldpiece shall not be liable for loss of use of the
instrument or other incidental or consequential dam­ages, expenses, or economic loss, or for any claim of
such damage, expenses, or economic loss.

Laws vary with jurisdiction. The above limitations
or exclusions may not apply to you.

Service

Return any defective SPDM1 Series meter to
Fieldpiece for warranty service along with proof of
purchase. Contact Fieldpiece for out of warranty
repair charges.

Auto off

Your meter will turn off automatically after 10 min­utes without use. After auto power off, press HOLD
button to restore power. The last reading shown
before it turned off will be displayed.

Data HOLD

Press HOLD button to keep the current range and
reading displayed until HOLD is pressed again.

Mode button

With the function set to VOLTS, press the mode
button to switch between AC and DC.

With the function set to Ω / / , press the
mode button to switch between resistance (ohms),
continuity, and diode test.

Non-contact voltage

The NCV function detects live AC voltage above
24VAC; sensitive enough to detect thermostat power.

1. Store leads in back of meter and switch to

OFF/NCV before using the NCV function.

2. Press and hold down the NCV button. The non-

contact voltage sensor is located at the red arrow

near the top of the meter. The closer the red

arrow is to AC voltage, the louder the beep and

the brighter the red LED.

3. Senses AC voltage between 24V and 600V.

Voltage AC/DC

1. With the function switch set to VOLTS, use mode
button to select AC or DC voltage.

2. Touch the probes to test
points as shown.

3. The meter will display the
voltage with the best
possible resolution. The
SPDM1 is an autoranging
meter so the decimal point will move to show
best resolution. Make sure you notice whether
the meter is displaying V (volts) or mV (millivolts).

Resistance and continuity

1. With the function switch set to Ω / / , use
mode button to toggle between ohms,
continuity, and diode.

2. Turn off power to circuit
being tested.

3. Touch probes to test
points as shown.

4. If mode is set to resistance
(Ω), the meter will display resistance with the best
possible resolution. Make sure you notice
whether the meter is displaying Ω (ohms), KΩ
(kiloohms), MΩ (megaohms).

5. If mode is set to continuity ( ), the beeper will
sound continuously if the resistance is less than
~25Ω.

Diode test

1. With the function switch set to Ω / / , use
mode button to select diode test.

2. Turn off power to circuit being tested.

3. Touch probes to the diode. A forward-voltage
drop should be about 0.6V.

4. Reverse probes. If the diode is good, “OL” is dis­played. If the diode is shorted, a value about 0.0V
will be displayed. If the diode is open, “OL” is dis­played in both directions.

Storing test leads

For convenient lead storage, open the back cover

and wrap the leads around posts.
