The display rotates in 90° steps for better reading

Automatic “Zero-Setting” in each measuring position using a special sensor technique

Selectable units of measurement: cN, g, N and lb

Very high data sampling rate (internal 1 kHz)

Storage of MIN, MAX, last reading, average and standard deviation per measuring interval

User-set MIN and MAX alarms with indication of TFT display if reading is out of limits

Adjustable electronic damping for better reading when tension fluctuates

3 separate calibration material memory locations for custom calibrations

Calibration adjustment for fine tuning of the calibration if material differs from the used calibration material

Menu set-up in English or German language

Standard Features

Rugged aluminium housing

LiPo accumulator (approx. 20 hours continuous operation) with AC adapter

CE certified, interference resistant against static electrifications

Certificate of Compliance with the order 2.1 according EN 10204 is included

Optionally available: Inspection Certificate 3.1 according EN 10204 with calibration report

Additional Special Features Model ETX

The tension meter ETX can be connected to a PC using the USB interface to monitor readings constantly on a PC

Memory for 60.000 readings

5 different memory modes can be selected by the operator:

  • Mode S: only statistical values per series are displayed
  • Mode H: storage of the X-Y-diagram for reviewing after finishing a series of measurement
  • Mode C: continuous logging over a user set time and max. 999 series of measurement (2 Hz)
  • Mode F: as C with higher sampling rate (200 Hz)
  • Mode D: storage of single readings and statistic

besonderheiten-pc-verbindungModel ETX can be connected to a PC with the USB cable. With the software SW-TI3 »Tension Inspect 3« readings can be displayed, statistically analysed and saved. For more information see “Standard Accessories ETX”
