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.
