contained in this user guide prior to installation and use
of the SCS Wrist Strap and Ground Monitor. Retain this
guide for future reference.
Intended Use
This user guide covers the SCS CTC337 Wrist Strap
and Ground Monitor. The CTC337 Wrist Strap and
Ground Monitor has two input jacks for monitoring
impedance and voltage on a dual conductor wrist strap.
It also monitors one metal ground in a workstation.
The Wrist Strap and Ground Monitor operates from
a universal AC power adapter. These systems are
typically installed on a machine with multiple tools or
on a workbench used for ESD-sensitive electronic
assembly or repair.
The systems must be installed as specified in this user
guide and are intended for use in an indoor commercial/
industrial environment. The system has not been
evaluated for other uses or locations.
Warning
To reduce the risks associated with hazardous voltage,
which if not avoided could result in electrical shock
related injury; the risks associated with environmental
contamination, which if not avoided could result in
environmental contamination related injury; and the risk
associated with false test results, which if not avoided
could result in property damage:
• Read, understand and follow all safety information
contained in this user guide for installation and use.

adapter or use it if damaged.
• Use the power adapter in an indoor dry location only.
Caution
To reduce the risks associated with environmental
contamination which, if not avoided, could result in minor
or moderate injury:
• Dispose of monitor in accordance with all applicable
local and government regulations.
Notice
To reduce the risks associated with property damage:
• Monitor must be checked periodically to verify each
monitor circuit is functioning correctly.
