Selecting Measurement Modes
The DFS1000 offers three primary measurement modes: Peak Tension, Peak Compression, and Tracking. Use the 'MODE' button to cycle through these options. The selected mode will be indicated on the LCD display. This feature is demonstrated in the video below.
Changing Units of Measurement
The device supports multiple units of measurement, including kilogram-force (kgf), pound-force (lbf), newton (N), and kilonewtons (kN). Press the 'UNIT' button to switch between these units. The current unit will be displayed on the screen. This feature is demonstrated in the video below.
Zeroing the Display
Before taking a measurement, ensure the display reads zero. Press the 'ZERO' button to reset the reading. This is crucial for accurate measurements.
Pass/Fail Limits
The DFS1000 allows you to set upper and lower pass/fail limits. If a measurement falls outside these predefined limits, the device will indicate a 'Fail' status using LED indicators. Refer to the device's menu for setting these limits. This feature is demonstrated in the video below.
Memory Storage and Data Logging
The device can store up to 500 readings in its internal memory. To save a reading, press the 'ENTER MEM' button. You can review stored results directly from the menu or download them to a Windows-based computer using the provided USB cable and 'NexGraph' PC software. This feature is demonstrated in the video below.
