SECTION 2
INSTALLATION
Digi Fence is designed so that the aluminum Scale can be mounted on the saw fence
rail and the Encoder can be attached to the moving part of the fence. A guide clip
connects the Encoder to the fence so the two move together. Figure 1 shows a typical
installation.

Calibration
There are two ways to set a zero reference (calibration).
Quick Method: Move the fence until it just touches the blade and depress the Zero
key on the front of the digital readout.
Best Method:
Cut a small piece of material. Measure the size with a caliper, and
use the + and - keys on the front of the readout to set in the correct reading.
When the correct reading is set, lock the Readout if desired. This prevents accidentally
re-zeroing of the readout. See Section 3 for more information about how to lock the
readout.
Maintenance
The Digital Readout should be cleaned periodically with compressed air to remove any
dust on the lens and keys. All fasteners should occasionally be checked for tightness.
Do not use any liquid lubricants on the scale assembly, as this may impede the
Encoder's ability to operate properly and attract other contaminants to the scale.

SECTION 3
OPERATION
Readout Keys
Timing
The keys pictured above have multiple functions. Timing, that is how long a key is
depressed, and the combination of the keys pressed, is important. This manual uses
the term ‘”momentarily” to describe a key press of typically less than 1 second.
Whereas “press and hold” is used imply a key press of typically longer than 1.5
seconds. As an example; when using a PC keyboard to type a capital letter you would
“press and hold” the SHIFT key and “momentarily” depress the LETTER key.
In addition, keep in mind the key’s “function” is executed on the key RELEASE, not the
key DEPRESS. This is important since some keys execute different functions based
on how long they are depressed. These key operations, once tried, quickly become
intuitive.
On/Off
Momentarily pressing the ON/OFF key will cause the Readout to turn on or off. The
Firmware Version is displayed on power-up when ON/OFF key is pressed. While on, if
no key presses or positional changes occur within 15 minutes, the Digital Readout will
automatically turn itself off to conserve battery life. While off, if a position change is
detected (.05mm or .002in) or the ON/OFF button is pressed, the Readout will
automatically turn itself on with no loss of measurement information.
Mode
The Digital Readout can display measurement information in decimal inches, fractions,
or millimeters. To change the current display mode, momentarily press the MODE key.
With each key press the Readout will cycle through decimal inches, fractional inches
and millimeters.
When the Readout is in 1/16 or 1/32 inch fraction mode, a series of “bars” in the upper
right corner of the LCD each represent an additional 1/64th of an inch measurement.
ie. When in 1/16 inch mode and three bars are showing, the measurement displayed is
rounded down to closest 1/16 inch and each illuminated bar indicates an additional
1/64 of an inch (“heavy”) measurement. For better resolution switch to 1/32 or 1/64
fraction mode. For the best resolution switch to a decimal mode. (Inch or mm).
Accurate Technology Digi Fence
Page 8 of 16
When the measurement is greater than 99 63/64 inches, a +100 and/or +200 will
illuminate in the upper right portion of the display to indicate this amount must be
added to the displayed reading. ie: If the measurement is 151 39/64 inches, 51 39/64
and +100 will be illuminated on the display. See photo below.
+, 0, and – Keys
The + (plus), 0 (zero) and – (minus) keys are used to change the currently displayed
position to a different value. The 0 key forces the unit to display 0. Momentarily
depressing the + key increments the current position by one unit of measurement.
Momentarily depressing the – key decrements the current position by one unit.
Pressing and holding the + or – keys will cause the displayed position to change
continuously. Holding down the key will cause the amount of change to speed up.
This allows for quick adjustments over a range of large values.
NOTE: While the 0 (zero) key can be used to simply “zero” the currently displayed
value, it can also be programmed to force the display to a preset value. This can be
zero, or any other displayable value.
See Programming Parameter Pr1
Accurate Technology Digi Fence

Display Resolution
The Digital Readout can be configured to display measurements with different
resolution.
In Normal display mode the resolution is: .01in or .01mm.
In Higher display mode the resolution is: .001in or .01mm
In Lower display mode the resolution is: .1in or .1mm.
Fractions remain the same for all settings: 1/16, 1/32 & 1/64
See Programming Parameter Pr4
Incremental Measurements
To make Incremental measurements, press and hold MODE key for approximately 3
seconds. This switches the Readout to INCremental mode (as shown in the upper left
corner of the LCD). You can now press the ZERO, + or – keys if desired. Any
measurement taken will be an incremental measurement and you will not lose your
original ABSolute position. While in the Incremental measurement mode, the Readout
can be re-zeroed for repeated incremental measurements by pressing the ZERO key.
To recall + and - offsets in Incremental measurement mode, simply press the MODE
key for repeated incremental measurements. Measurement units (in, mm, fraction)
changes are not allowed while in INC mode. To return to the ABS measuring mode,
press the MODE key for 3 seconds.
Lock Mode
The user can “lock-out” the position offset adjustment functions (+, -, 0 keys) to prevent
accidental changes of the current displayed position. To activate the lock mode, press
and hold the ON/OFF key and then momentarily press the MODE key. The word LOCK
will appear in the upper left corner of the LCD, and the +, - and 0 keys will not change
the displayed position.
For a more permanent keypad lock solution, See Programming Parameter Pr3
Reverse Scaling
If you set a zero point on ProScale, moving the scale in one direction will produce
positive readings. Moving the scale past zero in the opposite direction will produce
negative readings. Reverse scaling means changing the orientation of the Encoder so
that positive readings become negative and negative readings become positive. There
are two methods to reverse readings:
1. Slide the Encoder off the scale and re-install the Encoder in the opposite
direction, being careful not to damage the ground fingers inside the Encoder.
2. Change Programming Parameter Pr2

Changing the Batteries
A “BAT” indicator will appear in the upper left corner of the LCD display when new
batteries are needed.
Remove the screws in the upper right and lower left corners. Pull the cover off.
Remove the old batteries. Reinstall new AA Alkaline batteries, noting the proper
orientation. Replace the cover and tighten the screws.
CAUTION: DO NOT BEND BATTERY CLIPS!
THESE CLIPS ARE DESIGNED TO BE LOOSE WHEN THE CASE IS OPEN AND
WILL COMPRESS AND SECURE THE BATTERIES IN PLACE WHEN THE CASE
HALVES ARE SCREWED TOGETHER.

Programming Parameters
Programming Parameters are listed below. Values in [ ] are the available range of
values that can be programmed for that parameter.
Factory defaults are shown in Bold Red.
Pr 1: 0 Key Value
[0 to + 999.999in] or
[0 to +9999.99mm]
The programmed value that will be recalled whenever the 0 (zero) key is pressed during
normal operation.
Default = 0
Pr 2: Reverse Scaling
[0 or 1]
This parameter controls the sign of travel (positive vs negative) when the measuring
system is moved.
Default = 0
Pr 3: Key Lockout
[0 or 1]
This parameter controls the operation of the +, - and 0 keys. If enabled (set to 1), these
keys will not function and the word LOCK will appear on the display. This prevents
accidental changes when depressing these keys during normal operation.
Default = 0
Pr 4: Display Resolution
[1, 2 or 3]
This parameter sets the number of places to the right of the decimal point on the
display when the Digi Readout is in a decimal mode (in or mm).
A value of 1 will display x.x.
A value of 2 will display x.xx
A value of 3 will display x.xxx
Default = 2
NOTES:
Decimal inches have a maximum of 3 places.
Millimeters have a maximum of 2 places (even if parameter is set to 3.)
This setting has no effect when displaying fractions.

Frequently Asked Questions
What F/W (Firmware) version do I have?
The display will show d 2.xxx on power up. This is the firmware version of your
Readout.
What does “no Enc” mean?
If the Encoder cable is unplugged from the Readout, no Enc will appear on the display.
To clear: Be sure the Encoder is on the scale and plugged into the readout
The keys don’t seem to do what they are supposed to do.
Timing, that is how long a key is depressed, and the combination of the keys pressed is
important. This manual uses the term ‘”momentarily” to describe a key press of
typically less than 1 second. Whereas “press and hold” is used imply a key press of
typically longer than 1.5 seconds. As an example; when using a PC keyboard to type a
capital letter you would “press and hold” the SHIFT key and “momentarily” depress the
LETTER key.
In addition, keep in mind the key’s “function” is executed on the key RELEASE, not the
key DEPRESS. This is important since some keys execute different functions based
on how long they are depressed.
The battery clips seem to be very loose. Is this normal?
Yes. DO NOT attempt to bend these clips or wedge anything between them and the
case. These clips are designed to expand when the two case halves are screwed
together.
The readings are “backwards”?
You can change the “scaling” direction of the system by:
1. Reversing the orientation of the Encoder on the Scale.
2. Changing the value of Programming Parameter Pr 2.
