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
on display.

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
