Introduction
The Lafayette Pinch Gauge was designed as a diagnostic tool to measure the strength of
different pinch applications. The Lafayette Pinch Gauge has a real time force needle and a
peak hold needle. The real time force needle displays the current force being applied to the
gauge. The peak hold needle displays the maximum force that was applied during the trial.
Operation
The therapist holds the rounded end of the gauge supporting the weight of the instrument
with the pressure pad positioned toward the patient. The gauge must be “zeroed” before each
trial. To zero the instrument turn the center knob counter-clockwise until the peak hold needle
returns to zero. With the therapist still supporting the weight of the instrument, the patient
applies pressure to the pinch block and pressure pad with the thumb and nger being tested.

Service Tips
The Lafayette Pinch Gauge is designed to provide reliable service, with minimum maintenance,
over a period of many years. To make sure the instrument is reading accurately, it’s a good
idea to make a few checks, occasionally, as listed below.
Calibration
The instrument is calibrated at the factory using a custom calibration device. To ensure
proper operation, the instrument should be returned to the manufacturer for calibration on a
regular, preferably, annual basis. If the instrument has been dropped or there is some particular
reason to suspect that the calibration is in error, the instrument should be serviced by the
manufacturer immediately.

Zero Reading
The gauge needle may be above or below the zero
reading upon receipt of the instrument. The gauge
on this instrument is sensitive to pressure changes
due to changes in altitude and will most likely require
an adjustment to re-zero the instrument. Follow
these steps to return the gauge needle to zero:
1. Unscrew (counter clockwise) and remove the
lens from the gauge (the red peak-hold needle
is attached to the lens)
2. Remove the handle (to prevent applying
pressure during this process)
3. Place the instrument on a sturdy surface

4. Using a small slotted screwdriver, rotate the slotted screw counter clockwise in the gauge
dial face until the needle is below zero (if it is already zero, turn the cam until it is slightly
farther below zero)
5. Turn the screw in the reverse direction until the gauge needle is almost touching the zero line
6. Reattach the gauge lens and the handle
7. Pick up and squeeze to apply pressure to the instrument a few times
8. Place the instrument back on a sturdy surface and return the red peak-hold needle to zero
by turning the center knob
9. Check to see that the red peak-hold needle is at zero
10. If the red peak-hold needle is not on zero, repeat steps 1-10 until the red peak-hold needle
is at zero

Red Peak-Hold Needle
Check for excessive friction in the red peak-hold
assembly by turning the peak-hold knob in the lens
counterclockwise. If the peak-hold needle deects
the gauge needle, return the instrument for service.
Likewise, if the red peak-hold needle moves too
freely, (i.e. spins without pressure applied) return
the instrument for service.

Hydraulics
Any sign of hydraulic oil is an indication of damage to the instrument which requires service
by the manufacturer.
Wrist Strap
The Lafayette Pinch Gauge is equipped with a wrist strap. Simply place your hand through
the strap before pinching the pressure pad to protect the instrument from damage if dropped.
Warranty
The Lafayette Pinch Gauge has a 1 year parts and labor warranty. Please contact our service
department at [e-mail] to schedule your yearly calibration or repair.
Any attempt to service or calibrate outside of Lafayette Instrument will void the warranty.
