Fieldpiece SC53 - Dual Display Mini Clamp Meter - Manual

Autoranging
Autoranging meters automatically select the range
that gives you the best resolution. For example, when
measuring 24VAC, the meter will select the 40VAC
range and display "24.0". In the 400Vrange, you'd
see "24" and in the 4V range you'd see "OL" for over-
load. When an n (nano), μ (micro), m (milli), K (kilo),
or M (mega) shows up in the display, you must multi-
ply by 10
-9 , 10 -6 , 10 -3 , 10 3 , and 10 6 respectively.

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 meas-
urements. 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 cir-
cuit, disconnect the "RED" lead first, then the com-
mon lead. Work with others. Use one hand for test-
ing. Turn off power to the circuit under test before cut-
ting, 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 rms.
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 either display
shows the battery symbol to the right, the batter-
ies must be replaced for that display. Disconnect
and unplug leads, turn meter off, and remove the
battery cover on the back (two screws). The battery
on top is for the top display. The two batteries on the
bottom are for the bottom display. Replace with
CR2032 (3V) button-style batteries.
Limited warranty
This meter is warranted against defects in materi-
al or workmanship for one year from date of pur-
chase. 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 dam-
ages, expenses, or economic loss, or for any claim of
such damage, expenses, or economic loss.
State laws vary. The above limitations or exclu-
sions may not apply to you.
Service
Call Fieldpiece Instruments for one-price-fix-all
warranty service pricing. Send check or money order
for the amount quoted. Send the meter freight pre-
paid 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.

DUAL-DISPLAY DIGITAL
AUTORANGING
MINI CLAMP
METERS:
SC52, SC53 Description
The dual-display clamp meters can simultaneous-
ly measure amps through the clamp and any of the
functions on the dial of the meter. The amp clamp can
be turned on and off independently from the rest of
the meter to save battery life.
Non-contact voltage
Press and hold the NCV button. When the clamp
tip is close to an AC voltage, the NCV LED will light
and the beeper will beep. The closer you get to AC
voltage, the faster and louder the beep. The NCV
function is sensitive enough to detect 24VAC on ther-
mostats. (24V to 600V, 50Hz to 60Hz)
Capacitance (SC53)
For motor-start and motor-run capacitors, first dis-
connect the capacitor from power. Discharge the
capacitor by shorting the terminals before connecting
to meter. Disconnect any resistors that might be
between the terminals of the capacitor. If the capaci-
tor is connected to the meter and “dsc” symbol is
shown on the LCD, there is voltage in the tested
capacitor that needs to be discharged before testing.
Hold
There is a separate data hold function for each
display. The HOLD button on the side of the meter
corresponds to the AAC function and top display. The
HOLD button on the face of the meter corresponds to
the dial functions and bottom display. To keep the lat-
est reading displayed on the meter, press the HOLD
button relating to the display you want to freeze.
Press the HOLD button again to go back to normal
mode. The hold symbol “ “ on the display will then
disappear.
Auto off
Both displays have separate auto off features after
10 minutes of user nonoperation. The meter will beep
to announce the meter has turned off. If the ON/OFF
button is depressed when the top display is automat-
ically turned off, you will need to press it twice to turn
the top display on again. “APO” is shown on the dis-
play to let the user know that there is an Auto Power
Off feature for this meter. APO cannot be disabled.
Temperature (SC53)
Temperature measurement will be accurate even
in fast changing environments because of excellent
temperature compensation.
1. Remove leads and slide the Temp switch to the
right to close lead jacks.
2. Plug any K-type thermocouple directly into the
meter to measure temperature.
Field Temperature calibration
(SC53)
For accuracies of ±1°, calibrate to a known tem-
perature. A glass of stabilized ice water is very close
to 32
°F (0°C) and is usually very convenient but any
known temperature can be used.
1. Select 400
°F/C range and connect thermocouple.
2. Remove back case (2 screws on back, one near
clamp, other near base). Leave battery cover
attached so batteries stay within back case.
3. Stabilize a large cup of ice water.
4. Immerse the thermocouple
tip and let it stabilize.
5. To change the temperature
scale from °F to °C, close
the black jumper just
above the spring.
6. Adjust VR2 calibration pot
with a small screwdriver to
get within 0.1
° of 32°F
(0°C). Each 1/4 turn
should adjust the tempera-
ture about 3°, no more
than 10° total. There’s no need rotating the screw
more than 360°; doing so gets you back to where
you started.
7.Attach case without screws to preview the temper-
ature and continue until you have it dialed in.

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 thermocouple or the
jacks when the rotary dial is on OFF.
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.
