Fie
Never ground yourself when taking electrical
measurements. Do not touch exposed metal
pipes, outlets, fixtures, etc., which might be
at ground potential, while taking measurements. 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 fingers behind the finger guards
on the probes while taking measurements.
When disconnecting from a circuit, disconnect
the“RED”lead first, then the common“BLACK”
lead. Use one handed testing when possible.
Work with others.
Turn off 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 circuit before turning
any inductor off, including motors, transformers, and solenoids. High voltage transients
can damage the meter beyond repair.
Freeze the display.

Do not use during electrical storms.
Do not apply more than rated voltages between
input and ground.
Isolate capacitors from system and discharge
them safely before testing.
Temperature switch prevents leaving thermocouple plugged in while measuring voltage.
When measuring high frequency AC current, do
not exceed the rated 400AAC of the clamp.
Failure to adhere may cause the clamp to heat
up dangerously.
All voltage tests: All voltage ranges will
withstand up to 600V. Do not apply more than
600VDC or AC rms.

The new SC400 series clamp meters are
designed for HVACR service. Hang clamp meter
to any metallic surface with the redesigned
heavy-duty magnet and keep your hands free
to do more (SC440 only). See both voltage and
amperage readings at the same time on the
dual LCD display, even in low light conditions
using the bright blue backlight (backlight SC440
only). Take measurements with one hand using
the single test lead holder for added safety. Test
leads come with removable gold plated tips to
connect with Fieldpiece accessory heads.
Take more accurate VAC and AAC readings
on VFDs with True RMS sensing technology
(SC440 only). Measure the starting amp draw of
a compressor with Inrush current feature (SC440
only). Find the wire you want to test with the
automatic clamp jaw light (SC440 only).

Inrush feature captures starting current of a compressor motor.
Starting current can assist in diagnosing a motor before it fails.
To activate Inrush feature
1. Turn selector switch to VAC/AAC/Hz
2. Press SELECT once to show AAC on upper display.
3. Press INRUSH once to select 50AAC range. Press INRUSH twice to
select 400AAC range.
4. Clamp meter around compressor start wire. Turn motor on. The
starting current will hold on the upper display.
5. Hold INRUSH for 2 seconds to exit Inrush feature or press and
release INRUSH to measure starting current again.
Inrush measurement period: 100-milliseconds
Minimum input: >2A on 50A range; >20A on 400A range
! Note: AAC through the clamp and voltage through the test
leads can be measured simultaneously. However, if only AAC,
Frequency (Hz), or Inrush is measured through the clamp, test
leads and thermcouple must be unplugged from the meter.
Call Fieldpiece Instruments for one-pricefix-all out-of-warranty service pricing. Send
check or money order for the amount quoted.
Send the meter freight prepaid to Fieldpiece
Instruments. Send proof of date and location
of purchase for in-warranty service. The meter
will be repaired or replaced, at the option
of Fieldpiece, and returned via least cost
transportation.
For international customers, warranty for
products purchased outside of the U.S. should

For accuracies of ±1°F, calibrate to a known

is very close to 32°F (0°C) and is usually very
convenient but any known temperature can
be used.
1. Select the °F °C range.
2. Plug thermocouple to be
calibrated into the Type K jack.
3. Unscrew A and B and remove
the battery cover.
4. Stabilize a large cup of ice
water. Stir the ice with the
water until temperature stays
at a stable value.
5. Immerse the thermocouple
probe and let it stabilize.
Keep stirring water to prevent
micro-environments.
6. Do not let the thermocouple
come in direct contact with
ice.
7. Use a small screwdriver to
adjust calibration pot C below
