1.0 DESCRIPTION
The DTM Digital Tension Meter is designed and manufactured
using the latest technology for a high quality, compact, afford-
able instrument for use in industrial environments. Each unit has
a 3-1/2-digit LCD display with 0.6 inch (15.2 mm) high digits and
a DIP switch selectable decimal point.
The units are constructed of a lightweight, high impact plastic
case with a clear viewing window. The sealed front panel meets
NEMA 4X/IP65 specifications for wash-down and/or dusty
environments, when properly installed.
2.0 SAFETY SUMMARY
