Vermont Release Calibrater

What is a Calibrater?

The Calibrater is designed to measure the release torque of Alpine ski/boot/binding systems. Three components are necessary to conduct all tests: a FOOT, a LEG, and an ARM. The FOOT is a last, which is inserted into the boot. The LEG is an extension of the FOOT used for forward or backward lean tests. The ARM is a torque wrench, which is attached to the FOOT for twist release tests and to the LEG for forward or backward lean tests.

What’s Included?

The VRC-XX8c includes a LEG, Adult and Junior FOOT, Universal ARM, Tilt Vise with Mounting Hardware, Tool Hanger with Calibration Bracket, Torque Limiting Screwdriver with adapters, Short Ski Adapter, AT Adapter, Dead Hammer, Post-Accident Inspection Forms, Benchtop Reference Guide, Parts Kit #1 (including Replacement Release Indicators & Heel Strap, Elastic Stabilizer Shunt, Foot Collar, and Instruction Manual & DVD), and a foam-lined storage box.



How does it operate?

To perform a twist release test, the FOOT and Foot Collar are placed in the boot, the ARM is attached to the FOOT, grasped with a hand at each end, and rotated to release the binding. The release torque is read from the twist scale of the ARM. Separate release torque indicators are provided for clockwise and counter- clockwise measurements.


To perform a forward or backward lean release test, the LEG is attached to the FOOT, the strap is placed under the boot heel, the ARM is then attached to the LEG, grasped with one hand and pulled to release the binding. The release torque is read from the forward lean scale of the ARM.

Tilt Vise

The Tilt Vise supports the ski for twist tests and tilts to secure the ski at a convenient angle for forward lean tests. The vise can also be used to hold the ski during binding installation and repairs. A chip tray catches debris and automatically deposits it into a detachable plastic bag whenever the vise is tilted. The vise is now wide enough for fat and carving skis, and long enough for most all templates. Ski clamp pressure is adjusted with knobs located under the vise. A new adjustable center support is now included to preserve ski camber for systems with performance enhancement features.

Short Ski Adapter

If the ski is too short for the Tilt Vise, the Short Ski Adapter is slipped over the tail of the ski and the box tube frame of the Vise. The Adapter is then clamped in place as if it were a ski.


Dead Hammer

Use the Dead Hammer in place of the palm of your hand to test the binding toe piece for correct anti-shock performance. Be careful not to strike buckles or other boot fixtures.

Torque Limiting Screwdriver (TLS)

The Torque Limiting Screwdriver (TLS) is preset at the factory to approximately 4 Newton meters (Nm) torque and is marked with a red cap. Units set to 3 Nm are marked with a black cap. When the TLS clutch releases, it is an indication to the mechanic that the preset torque has been reached. The Torque Limiting Screwdriver can also be used to check the preset torque of power screwdrivers.

How to inspect your Calibrater

Check the following prior to each use of the Calibrater. If deficencies are noted in any of the following areas, consult the Maintenance and Repair sections of the manual. Replace damaged, worn, or missing parts immediately.

  1. Make sure that the yellow release torque indicators point to zero. To do this, move one indicator at a time up against the wand. Each indicator should point to within 1/4 of the smallest division of zero.
  2. Check that the release indicators are intact and can move freely, with some resistance, but do not bind in the slot. Check also that they correctly follow the wand and do not jump or slip back when the binding releases.
  3. Make sure the wand does not drag on the scale or the protective frame and that it does not touch the beam.
  4. Make sure the scale and the frame that supports it are not damaged or bent.
  5. Check the cable strap assembly for damage and wear. Check the strap for abrasion and the cable for kinks or broken wires.
  6. Check the elastic stabilizer for damage or wear. Make sure the plastic cable sleeve is lubricated with a thin film of Armorall.
  7. Check the rubber bumpers and pads on Vise for tears or cracks. Check all clamps for proper function.
  8. Check the Vise hinge (or cable) for kinks (or broken wires).
  9. Make sure the FOOT is not bent or otherwise damaged. Make sure the plastic coating is lubricated with a thin film of Armorall.
  10. Check the top of the FOOT shaft for damage or wear. Make sure that it fits the socket at the bottom of the LEG.

Routine Maintenance

Most routine maintenance and component replacement operations can be performed in the shop. Calibrater components do not need to be returned to the factory except as required.


Keep the yellow release torque indicators and their track clean. Replace the indicators when damaged or loose. It is a good practice to replace them annually. When properly inserted they should point directly across the slot in the scale. ARMs with red, black, or blue scales should be updated. At the beginning, and at least once during the season, the calibration of the ARM should be verified using a dead weight. Calibration checks should also be made whenever the accuracy of the Calibrater is called into question. Return the ARM to VSSE if damage or wear cannot be corrected or if proper function cannot be restored.


Keep the steel socket at the bottom of the LEG clean, smooth, and lubricated with a thin film of silicone. Straighten any kinks that develop in the cable. Replace damaged or worn cables or straps. Always use clevis pins and split rings supplied by VSSE for reassembly. Keep the plastic covering of the cable lubricated with a thin film of Armorall to allow the stabilizer to slide easily. Replace the stabilizer when broken.
