Superspars ISP rig gauge
Superspars rig tension gauge, for measuring the tension in 2.5-4.00 mm wire
How To Use The ISP Tension Meter
|To measure the tension of any 1x19 wire, slide the slot in the lower part of the "Meter" over the wire as shown in Fig. 1.|
|Now, using the white nylon cord, pull the outer spring away from the wire until the pointer on it's top is level with the calibration line on the scale on the top of the inner spring, Fig. 2.|
|Read the scale number from this scale by using the centre of the wire itself Fig. 3. Next, from the table on the reverse of the meter, find the scale number on the left hand side and read the corresponding "tension" for your wire diameter.|
Note: This tension reading is only accurate for 1 x 19 (normal rigging wire). Avoid touching the wire with the Meter as this could give a false reading.
