Introduction
1.0 Summary and Features
The Edmunds Gages Accusetter II offers many sophisticated features and benefits for
durable and robust shop floor operation.
The Accusetter II is a microprocessor based gaging column that combines a 101 discrete
tri-color LED bargraph display for easy visual monitoring of dimensional measurement
characteristics, with an eight digit alpha numeric display for precise size readings and
operator prompting messages. Illuminated range indicators identify which of the eight
inch or eight millimeter ranges have been selected. The tri-color LED bargraph conveys
both measurement size and status. A single rotary entry switch and six dedicated
pushbuttons provide all of the operator control functions.
The unit is housed in a heavy duty reinforced aluminum case with a module bay for
interchangeable plug in modules which will accommodate Edmunds LVDT type gaging
probes or Edmunds and nearly all major brands of air tooling. The rear panel of the
column contains two female DB25 connectors which provide 6 channels for input/output
bussing of analog signals. These connectors also provide various control/status signals
for the I/O accessory board. An RS-232C connector allows output of gage results to a
data collector. The Accusetter II will operate at any supply line voltage between 100
VAC to 240 VAC at either 50 or 60 HZ. An additional receptacle is provided for power
jumper cord connections for multiple column applications. The serial number with
revision letter is identified at the top of the rear panel of the Accusetter II.
The Accusetter II’s powerful microprocessor allows the user tremendous flexibility in
tailoring the column to match the gaging requirement. Each dimension can be
functionally displayed as a deviation from nominal, absolute size, +peak, -peak, TIR or
class functions. The automatic mastering provides precise calibration without the usual
need of precisely adjusting trim pots and knobs. The user is provided with three distinct
application gaging programs to choose from. The single check program simplifies the
operation of the Accusetter II to allow only a single check measurement. The multiple
check program is Accusetter II’s unique “4 in 1” feature that allows the user to configure
up to four dimensional checks to be gaged simultaneously in one column. In the multiple
fixture program, an enhanced single check measurement is available for up to four
separate gages. Whenever power is first turned on to the Accusetter II, the display will
scroll the software version and the present application program and the module ID.

1.2 Anti-Static Precautions
When working inside the Accusetter II cabinet or handling signal conditioning modules
use caution to protect against damage from static electricity. Use of an anti-static wrist
band or other grounding procedures are recommended.
Power to the column must be turned off prior to installing or removing a signal
conditioning module.

1.3 Glossary of Terms
Absolute displays the check size as the actual part size.
An A/E (Air to Electric) transducer converts changes in pneumatic pressure into an
electrical signal.
+APPROACH(or -APPROACH) are optional user defined programmable values
approaching the max and min part limits.
AVG (Average) is a function that returns the average check reading.
Bypass is a function that displays a live input reading
A part Check is an input or combination of inputs expressed with a gaging mode to
exhibit a part characteristic.
Calibration is a procedure used to automatically set the magnification and zero shift for
a check by comparing actual gage readings to known certified sizes of a master or
masters.
Deviation displays how much a check size deviates from the nominal size as a variation.
A gaging Formula allows the user to add, subtract, multiply, or divide inputs from
transducers A, B, C, and D.
AFunction defines how an input or check will be displayed on the readout. Function
options are Bypass, Average, +Peak, -Peak, TIR, and TOL Check.
The Gain setting on the A/E signal conditioning module sets the amplification factor of
an input signal to a usable value that can be interpreted by the readout device
A Gage is a mechanical device used to measure part characteristics.
Gage Readings are the input values obtained during the gage cycle.
A High Level Signal is an amplified +/-2.5VDC signal that reflects the number of bars
illuminated on the bargraph display.
An Input is the assigned name given to a signal that is to be utilized in a gaging formula.
In LIVE RDG(Live Reading) mode the input signal is directly displayed on the
alphanumeric and bargraph displays in real time.
A Low Level Signal is the raw unamplified voltage from an LVDT or A/E transducer.

1-4
An LVDT(Linear Variable Differential Transformer) is an electromechanical
transducer that converts the linear motion of its contact tip to an AC voltage which can be
interpreted by a readout device.
Magnificationis the enlargement of an input signal to a usable value that can be
interpreted by the readout device.
A Maximum (MAX)Master is a precision replica of the gaged part manufactured to the
upper specification limit of the part features, inspected and certified to size, for use in the
calibration of the gage.
A Minimum (MIN)Master is a precision replica of the gaged part manufactured to the
lower specification limit of the part features, inspected and certified to size, for use in the
calibration of the gage.
A Multiple Check Program allows the user to program up to four dimensional checks to
be gaged simultaneously in one column. All checks must use the same range.
AMultiple Fixture Program allows the user to program the Accusetter II with up to
four separate gages each consisting of a single check. The gages can use different ranges.
AMultiplieris part of the check formula. The input reading is multiplied by the this
factor. It is determined by the number of probes used to perform the measurement or to
correct any ratio that may be introduced by any contact arms or tooling.
Polarity is the signed value (+ or -) applied to the magnification of an input to determine
the direction of the input value change.
In +PEAK(or -PEAK)modes the largest (or smallest) size reading since the last reset is
displayed.
Range is the full scale value of the bargraph display.
An R & R is a statistical study performed on a gage to determine the gages repeatability
and reproducibility.
Repeatability is the measurement variation of a gage when used by one operator or
under one set of environmental conditions.
Reproducibility is the variation in measurement averages of a gage when used by more
than one operator or under varying environmental conditions.
The Resolutionof a gage is the smallest significant digit of the measurement data that is
displayed.
In Run Mode the user can perform the actual part measurements.

1-5
A Signal Conditioneris a circuit board that modulates and amplifies the LVDT or A/E
signal used by the readout device.
ASingle Check Programallows the user to program the Accusetter II for one
dimensional check.
In Setup Mode the user can program the required variables for the par checks and
transducers.
In TIR (Total Indicator Reading) mode the difference between the largest and smallest
readings measured is displayed.
TOL Check is a check function that displays the average reading measured when the
check is within the programmed tolerance limits and displays the +Peak or -Peak
readings when the check result is outside the programmed tolerance limits.
A Zero (or Mean) Master is a precision replica of the gaged part manufactured to the
nominal dimensions of the part features and calibrated to size for use in the calibration of
the gage.
A Zero adjustment knob allows operator to drive the displayed readout value to a
desired setting within a limited range.

1.4 Quick Start Guide
The following steps must be taken to prepare the Accusetter II for operation.
1) Unpack and setup the unit.
•Rotate the front foot 90°from its shipping position.
•For air gaging applications, rotate the rear foot 180°from its shipping position and
install the filter regulator assembly. Connect 60 psi min supply air to the filter
regulator assembly
Note:See "Basic Operations, Unpacking & Setup" for additional information, page 3-1
2) Setup and install the signal conditioning module if it was not installed before
shipment and connect the gage tooling.
Power to the column must be turned off prior to installing or removing a signal
conditioning module.
•Check that the jumpers and switches on the LVDT or A/E signal conditioning board
to be used are properly setup for the application to be run.
•Install the signal conditioning module into the lower bay and secure with the two
thumb screws on the front panel.
•Plug in the LVDT(s) or airline from the gaging fixture to the signal conditioning
module.
