1. Introduction
Equipment Description
The Interface Force Verification Frame (IFVF) is a portable high force capacity
frame and accessories designed to apply tension and compression forces to load
cells with high resolution and accuracy. The system features a portable reaction
frame, manual actuator, thread/adapter accessories, and optional force sensor(s)
and instrumentation. The hardware can be used to verify operation of a device
under test or calibrate relative to a second reference load cell.
The base IFVF system includes the frame and tension/compression adapters.
Load cells, indicators, and additional adapter hardware are sold separately. The
items have been designed by Interface Inc. to work fully together for most common
applications.

Theory of Operation
Turning the handles clockwise imparts a linear compression movement of
~0.007” per turn. Turning the verification frame handles counter-clockwise
imparts a linear tension movement of ~0.007” per turn. The exact level of
deflection changes based the stiffness of the load cell and/or device under test.
The force created is contained and reacted through the structural frame. The
Reference Load Cell measures the force being applied to the Device Under Test.
The verification frame can be used to verify operation of a Device Under Test or
calibrate relative to a second reference load cell.

2. Warnings
General
It is very important that you study the following safety information as
to not result in a hazardous situation or equipment damage.
1. DO NOT SHOCK LOAD HANDLES WHILE TURNING/ACTUATING. Use only
smooth and gentle pressures with gradual accelerations and decelerations.
2. HARD STOPS are located at full extension and retraction of the actuator. Do
not apply high force or attempt to actuate past these hard stops. Damage to
the internal members of the verification frame will occur from overpressure at
hard stops.
3. Do not allow personnel to operate the verification frame who are not
experienced or trained in its use.
4. Keep fingers and hands free of potential pinch points of the verification frame.
Be aware of operating conditions at all times.
5. Do not exceed the verification frame force capacity of 2,500lbf by more than
10%.
6. Replace, remove and install hardware adapters only when verification frame is
unloaded of all levels of force.

3. System Operation
Setup
1. Clamp or bolt the verification frame base to a sturdy surface. Ensure that
turning handles can freely rotate and are not obstructed.
2. Install desired hardware adapters needed for use.
a. Compression: Compression Platen
b. Tension: Tension Post/Cup
3. Position the bottom horizontal reaction frame member as
needed by removing and re-installing T-pins on the two vertical
side rails. Do NOT remove T-pins while any force is being
generated within the reaction frame.
4. Install load cell(s) within reaction frame per manufacturer guidelines.
5. Connect load cell wiring to indicators to display force values per manufacturer
guidelines.
Operation
1. Compression
a. Turn actuator counterclockwise gently until hard stop is reached, then turn
actuator 1 turn clockwise. Reference Figure 1.
b. Manually rotate compression platen until contact is made between loading
surfaces. Observe force increase/changes on electronic display.
(Between 0 and 30lbs actuation may be somewhat
non-linear as threaded connections engage unevenly.)
c. Rotate handles clockwise to increase compression magnitude.
d. Rotate handles counter-clockwise to decrease compression magnitude.
2. Tension
a. Turn actuator clockwise gently until hard stop is reached, then turn actuator
1 turn counterclockwise. Reference Figure 1.
b. Thread the Post of the Post/Cup Adapter into the load cell or Device Under
Test. Next, vertically position the Cup of the Post/Cup Adapter to best align
it to the Post. Using the Force Actuator turn handles, fine position the

www.interfaceforce.com Page 8of 10
concentricity of the Post and Cup and then cross pin the two features
together.
c. Rotate handles counter-clockwise to increase tension magnitude.
d. Rotate handles clockwise to decrease tension magnitude.
Maintenance
The system is designed to operate with minimal maintenance requirements.
However, periodic maintenance should be performed to ensure trouble free
operation.
1. Daily
•Ensure handles turn smoothly throughout its range and do not bind
during movements.
2. Weekly
•Wipe down any surfaces that appear dirty.
•Apply light machine oil to cup/post hardware and thread adapters.
3. Monthly
•Inspect all moving joints for signs of wear/damage.
•Verify all fastener hardware is torqued and not loose.
