1.0 INTRODUCTION
The Checkline ETB/ETPB tension meters accurately measure tension on fine wires,
yarns and fibers. Rollers or ceramic pins are mounted at the end of long “fingers”
permitting the user to measure tension with limited access space or when several lines
are closely spaced such as on a warp sheet.
Features include color, backlight TFT-display with 3 different displays modes: numeric,
numeric with live bargraph, numeric with graph (time vs tension). The display auto
rotates in 90° steps for optimal visibility regardless of the position of the tension meter.
1.1 Delivery
ET Series gauges are delivered as a complete kit
including tension meter, built-in rechargeable
battery and USB/AC adapter with country adapters
(EU, US, UK, AUS/NZ) and operating instructions
all supplied in a foam-fitted carrying case.
Optional: NIST-Traceable Calibration Certification.
1.2 Precautions
The device must not be operated in potential explosive areas and must
not come into contact with aggressive substances.
Tensions that exceed the tension range of the instrument by more than
100% may cause permanent damage to the measuring spring and must
be avoided under any circumstances.
For cleaning the unit do not use any aggressive solvents such as
trichloroethylene or similar chemicals. No warranty or liability shall be
accepted for damage resulting from improper cleaning.
1.3 Verification interval
The question of finding the right frequency of calibration accuracy verification depends
on several different factors: Operating time and load of the tension meter, olerance band
defined by the customer, hanges to the tolerance band compared to previous calibrations
Therefore, the interval between verifications of calibration must be determined by the
user‘s Quality Assurance Department, based on the user‘s experience. Assuming normal
operating time and load as well as careful handling of the tension meter, we recommend
a verification interval of one year.
