A typical ProScale measuring system consists of three major parts:
•SCALE –an aluminum extrusion to which a printed circuit board with a
unique pattern is bonded.
•ENCODER –a readhead or sensor that traverses the SCALE to determine
a position or distance from some arbitrary point of origin.
•DIGITAL READOUT –or DRO, is the component that displays the
measurement or position information sent by the ENCODER.
The Readouts covered in this Manual are compatible with these SCALES:
ProScale Models 150, 250 & 950 series systems, (and products based on
these systems), incorporate Absolute measuring technology and may include
any of several Digital Readouts including some not covered in this manual.

12-24VDC Operation
The General Purpose and the In-Panel Readouts will operate on 12-24VDC.
The General Purpose Readout uses a multi-purpose plug-in connector for
power as well as input and output signals.
The In-Panel Readout uses screw terminals for these connections.
Also, See Section 3: Circuit Board Jumpers
General Purpose Readout
In-Panel Readout
When powering Readouts with 12-24VDC, the Scale and the Readout common
must be connected to each other, or connected to each other via a common
point. A proper connection will eliminate ground loops that may cause unstable
readings on the Readout.
NOTES: When using Model 150, 250 or 950 operated on 12-24VDC, use
only Scales, & Encoders with part #’s end in ‘G’.
12-24VDC Readouts are designed to run on DC VOLTAGE ONLY.

SECTION 3 OPERATION
Initial Set-up
In most instances it will be desirable to set some initial parameters such as a
reference point, measurement units and resolution for your measuring
application.
Measurement Units
The measurement units that are displayed (inch, mm, cm) are
selected with the UNITS Key.
Current Position
The ProScale Readout allows the current position to be
easily configured, using the +, - and (optionally) DATUM
Key.
Reference Point
The ProScale Readout allows a reference point (zero or other value)
to be easily recalled using the DATUM Key. The value of this
reference point is programmed in Programming Parameter Pr1.
Reading Direction
The direction of the reading as the measurement system is moved is
programmed using Programming Parameter Pr2.
Resolution
The resolution of the displayed units is programmed using Programming
Parameter Pr4.
Additional Initial Set-up items MAY include:
Auto On/Off
Key Lock
Scaling

Operation Manual for LCD Digital Readouts Page 16 of 53
Readout Key Timing
Several keys on the Readouts have multiple functions.
How long a key is pressed is important since the function executed when a key
is pushed is dependent on how long it is pressed.
This manual uses the term “Momentarily” to describe a key press of less than .8
seconds, and “Press and Hold” to describe a key press of longer than 1
second.
For Momentary key press operations, the Function is executed when the key is
released.
For Press & Hold operations, the Function is executed after the key has been
pressed and held for the prescribed amount of time.
See the chart below for a summary of the functions performed by the keys below:

Readout Key Functions
On/Off Key
Momentarily press the ON/OFF key to turn the Readout on or off.
(The Readout Firmware (F/W) version displays for two seconds at power-on.)
Units Key
Momentarily press the UNITS key to cycle through decimal inches, fractions
(16ths, 32nds and 64ths) and metric (millimeters or centimeters) measuring
modes. To configure the measurement modes that are displayed when
pressing the UNITS key use Programming Parameter (Pr11).
When the Readout is in 1/16 or 1/32 inch fraction mode,
a series of “bars” may appear in the upper right corner of
the LCD. Each bar represents 1/64th of an inch. (i.e. when in 1/16 fraction
mode and three bars appear, the measurement displayed is rounded down to
the closest 1/16 inch, plus each illuminated bar represents an additional 1/64 of
an inch, for an actual fractional measurement of 7/64ths of an inch.) For better
resolution, switch to 1/32 or 1/64 mode. Or better yet, to decimal Inches.
In Fractions mode, when the measurement is greater than
99 63/64 inches, +100 and/or +200 will illuminate in the upper right portion of
the LCD to indicate this amount must be added to the displayed reading. (i.e.: If
the measurement is 154 5/8 inches, 54 5/8 and +100 will appear on the LCD, If
the measurement is -307 23/64 inches, - 7 23/64, +100 and +200 will appear on
the LCD.
Momentarily Press
Momentarily Press

Operation Manual for LCD Digital Readouts Page 18 of 53
Plus (+) & Minus (–) Keys
Momentarily pressing the +or –key will increment or decrement the current
displayed value by one unit of measurement. (in, mm, cm or 1/64)
Press & Hold the +or –key to continue to increment or decrement the
displayed value. The longer the key is pressed, the faster the changes occur.
The + &–keys may be locked out to prevent accidental entries by using
key lock and/orProgramming Parameter (Pr3).
Datum Key
Momentarily pressing the DATUM key forces the Readout to a user programmed
value. This can be zero or any other displayable value.
Set the DATUM key programmed value with Parameter (Pr1).
Press and Hold the DATUM key for 6 seconds to display the battery voltage.
Press and Hold the DATUM key for 9 seconds to display the temperature.
The temperature is displayed in “F” or “C” based on the current units setting
(Inch or Metric).
The DATUM key may be locked out to prevent accidental entries by using
key lock and/orProgramming Parameter (Pr3).

Fundamental Readout
Functions
Auto On/Off Timer
To prolong battery life, the Readout has a built-in function that turns off the
Readout after a period of no movement or key activity. The Auto On/Off
function is programmable from 0 (always on), to 240 (minutes) before entering
sleep mode.
Press the ON/OFF key or move the measurement system to wake up the
Readout. Any key press or system motion while the Readout is awake restarts
the Auto On/Off timer. Use Programming Parameter (Pr12) to set this interval.
Reading Direction
If the direction of readings, (increasing vs. decreasing) is opposite the desired
direction, use Programming Parameter (Pr2) to reverse the Reading Direction.
Resolution
The Readouts have four selectable display resolutions.
Fractions display mode is not affected by resolution changes.
.1in .1mm .1cm or
.01in .01mm .01cm or
.001in .01mm .001cm or
.0005in .01mm .001cm
Use Programming Parameter (Pr4) to set the displayed resolution.
Data displayed (and sent to the SPC output) is auto-ranging. This means the
selected resolution may be temporarily overridden if the measurement or
position to be displayed exceeds the maximum displayable value for the
programmed resolution. The Readout will continue to automatically reduce the
resolution to 1 decimal place or until an allowable resolution is achieved. The
available resolutions are:
Inch Resolution

Key Lock
The Readout provides a function that can “lock-out” the position adjustment
keys (+, DATUM &–) to prevent accidental changes of the displayed value.
To activate Key Lock: Press and Hold the ON/OFF key and, while pressing it,
Momentarily depress the UNITS key, now release both keys. The word LOCK
will be displayed in the upper left corner of the LCD.
When LOCK is displayed on the LCD, the +, DATUM and –keys will not
function to change the readout. To de-activate the Key Lock: Press and Hold
the ON/OFF key and, while pressing it, Momentarily depress the UNITS key, now
release both keys. Key Lock may also be enabled through Readout
Programming. This method allows a more permanent Key Lock since
programming can be disabled with a hardware jumper inside the Readout.
See Programming Parameter (Pr3) to enable this function.`
Linear Scaling
This function is useful when the actual measurement or position must be
multiplied or divided before being displayed on the Readout.
This function has a range of 0.0001 to 9.9999 allowing the actual measured
value to be multiplied or divided in very small or very large increments.
See Programming Parameter (Pr13) for additional information.
Use care when enabling this function. It will force the readout to display a value
different from the actual measurement or position.
