WARNINGS

DISCONNECT AND UNPLUG TEST

LEADS

before opening case.

TEST NCV FUNCTION ON KNOWN

LIVE WIRE before using.

DO NOT APPLY VOLTAGE greater

than 30VAC or 60VDC to the thermocou-

ple or the jacks when the rotary dial is on

°F.

REMOVE

THE THERMOCOUPLE

when taking voltage measurements.

DISCONNECT

THE TEST LEADS

when taking temperature measure-

ments.

DO NOT APPLY VOLTAGE TO THE

JACKS when the rotary dial is on

microamps. Even low voltages can cause

a current overload and blow the fuse.

Replace blown fuse to regain function.

Maintenance

Clean the exterior with clean dry

cloth. Do not use liquid.

Battery replacement: When the

multimeter displays " " the battery

must be replaced. Disconnect and

unplug leads, turn meter off, and

remove the battery cover. Replace the

battery with a NEDA type 1604 9V bat-

tery.

For your safety...

General: Disconnect the test leads

before opening the case. 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 poten-

tial. Keep your body isolated from

ground by using dry clothing, rubber

shoes, rubber mats, or any approved

insulating material. When disconnect-

ing from a circuit, disconnect the

"RED" lead first, then the common

lead. Work with others. Use one hand

for testing. Turn off power to the circuit

under test before cutting, unsoldering,

or breaking the circuit. Keep your fin-

gers 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: For model SC76

all voltage ranges will withstand up to

600VDC or 600VAC. Do not apply

more than 600VDC or 600VAC.

AC tests: Disconnect the meter

from the circuit before turning any

inductor off, including motors, trans-

formers, and solenoids. High voltage

transients can damage the meter

beyond repair. Do not use during elec-

trical storms.

Symbols used:

Caution, risk of electric shock

Caution, refer to manual.

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, alter-

ation, or unreasonable use of the

instrument.

Any implied warranties arising from

the sale of a Fieldpiece product,

including but not limited to implied war-

ranties 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.

State laws vary. The above limita-

tions or exclusions may not apply to

you.

Works with Fieldpiece

accessory heads

Connect your Fieldpiece accessory

head to SC series meter through

included deluxe silicone leads. Use

340mVDC or 3400mVDC range for

most heads.

SC76 connected to

ARH4 through leads.

Available Fieldpiece

accessory heads

There is a Fieldpiece accessory

head available for just about any job.

There are heads to measure tempera-

ture, RH%, wet bulb, dew point, vacu-

um (microns of mercury), manometer

(inches of water column), amps

AC&DC, high voltage, CO, CO2, air

velocity, and many more.

Non-contact voltage

With the NCV tab on the tip of the

clamp close to an AC voltage, press

the NCV button. The NCV LED will

light and the beeper will beep. The

NCV function is sensitive enough to

detect 24VAC on thermostats.

Hi voltage indicator

In any VAC/VDC range, when you

touch a voltage greater than 30V, the

beeper will beep and the red Hi-V LED

will blink. BE CAREFUL!

Current measurements

The fixed jaw is longer than the

moveable jaw to make it easier to

select just one wire from a bundle.

With the jaws closed, separate one

wire using the long fixed jaw. Slide it to

the corner where the two jaws meet.

Then open the jaws to let it in. You can

select the wire without having to hold

the jaws open.

Microamps

For measuring the flame diode cur-

rent in a heater control.

Capacitance

For motor-start and motor-run

capacitors. Disconnect the capacitor

from power first. Short the terminals to

discharge the capacitors. Disconnect

any resistors that might be between

the terminals of the capacitor.

Temperature

Plug any K-type thermocouple

directly into the meter to measure tem-

perature. Temperature measurement

will maintain good accuracy in fast

changing environments. One thermo-

couple is included. No adapter is

required.

Display ºC or ºF

Remove back of meter, locate

jumper on lower right corner of PCB

(just below VR3) and close jumper to

read temperature in °C.

Field Temp. calibration

For accuracies of ±1° calibrate the

SC76 to a known temperature. A glass

of stabilized ice water is very close to

32°F (0°C) and is usually very conven-

ient.

1. Select the °F range on the SC76.

2. Remove back case. Hold the bat-

tery in place with a rubber band.

3. Stabilize a large cup of ice water.

4. Immerse the probe and let it stabi-

lize.

5. Adjust VR3 (lower right corner of

PCB) to get close to 32°F (0°C)

then adjust VR4 (below VR3) to get

within 0.1°F/C of 32°F (0°C).

6. To calibrate in °C, close the jumper

that is to the left of VR3.

Using & storing test leads

Because the wire insulation is sili-

cone they will stay flexible in cold

weather and will not melt if bumped by

a soldering iron.

Use the single test probe holder on

clamp to make voltage testing easy.

For convenient lead storage, wrap

the leads as shown.
