Quick Start
1. For electrical testing, connect test leads to
"COM" and "+" jacks. For temperature testing,
remove test leads and slide TEMP switch to
the right.
2. Rotate the dial to your desired function. Press
SEL to cycle through the parameters within
the switch position.
3. Connect to test points and read measurement

Description
Your SC54 is a swivel clamp meter specially
designed for the HVACR technician. The swivel
on the SC54 allows you to get a good viewing
angle on the display while taking amperage
readings through the clamp, regardless of the
wire orientation. The SC54 has the functions
you want as an HVACR technician.
Get fast manual ranging performance on an
easy to use auto-ranging clamp meter.
The SC54 is compatible with Fieldpiece
accessory heads allowing you to measure many
parameters on the SC54 display.

makes it easier
to use in any lighting condition. True RMS helps
you take more accurate voltage and amperage
readings on variable frequency drives.
The unique temperature circuit allows the
SC54 to get accurate temperature readings
faster when moving from a rooftop to a freezer.
The easily accessible field calibration allows
you to calibrate the temperature on your SC54
without hassle.

Fieldpiece accessory head. See Modular Expandability section on
reverse page for more details.
Ranges: 1000mV and 10000mV
Accuracy: ±(0.5% + 5 dgts)
Resolution: 0.1mV or 1mV Input impedance: 1MΩ
MicroAmps DC (µADC)
Microamps for flame rectifier diode test on a heater control.
Connect leads between flame sensor probe and control module and
turn heating unit on to read µA measurement. When the flame is on,
there should be a measurable µADC signal, typically under 10µADC.
Compare measurement to manufacture’s specification to determine if
replacement is necessary.

Accuracy: ±(1.0% + 5 dgts) Voltage burden: 1V
Overload Protection: 600VDC or 600VAC rms
Frequency (Hz) Through Leads
Check variable frequency drives. Check incoming voltages to
ensure they are cycling at 60Hz or desired frequency. Select VAC/Hz
and press SEL button.
Ranges: 20 to 400Hz Resolution: 0.1Hz
Accuracy: ±(0.5% + 5)
Sensitivity: 5V rms on VAC range.
Capacitance (MFD)
Capacitors are one of the most failure prone components in
a HVAC/R system. Set to MFD/Ω/
