Item Type: Dial Tension Material: ABSAlloy+ Color: As shown in picture Model Specification: SEG301-- Pointer: Single pointer Measurement Value: 30g Graduation Value: 1g Scale : 5305-- Accuracy: 05±. Application: dial tension is suitable for relay tip pressure, electronic , , valve, spring pull pressure, dial measure equipment pressure, dial system equipment tip and gag bitmechanical pressure, tape recorder buffer mechanism pressure, and other pressures, pulling force test. How to Use: When test, use Pin Head move object from static state to position needed. tension test not only along clockwise, but also along anticlockwise-. Pin Head must always vertical to pushpull- force direction. Tension set off single Pin Head and dual Pin Head. singlepointer- tensiometer measures and reads immediately. When dual Pin Head tension gets highest value, Pin Head hold still, convenient user to read. Package List： 1 x Dial Tension Note: 1. Do not drop product randomly. 2. Do not bend measuring alloy probe. 3. When product cannot be calibrated, you can open back cover for calibration. It is not recommended to open back cover for calibration frequently.
