ON/OFF

Momentarily pressing the

ON/OFF

key will cause the display to turn on or off. The

Firmware Version is displayed on power-up or when

ON/OFF

key is pressed. While on, if

no key presses or positional changes occur within 15 minutes, the Digital Display 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 display will

automatically turn itself on with no loss of measurement information.

(Programming Parameter Pr8. Factory default set to 15 minutes.)

Battery voltage is displayed by pressing and holding the

ON/OFF

key for 5 seconds while

display is turned on.

CAUTION: Pressing and holding the ON/OFF and MODE key for 10

seconds

while the display is turned off

will perform a full segment LCD

test AND re-set all programming parameters to factory defaults

MODE

The digital display can show measurement information in Imperial or Metric. To change

the current display mode, momentarily press the

MODE

key. With each key press the

display will cycle through decimal inches, fractional inches (1/16), (1/32), (1/64) (If

enabled by

Programming Parameter Pr6

) and metric (mm or cm based on setting of

Programming Parameter Pr5

When the display is in a decimal mode (mm, cm or in) it will auto-range to the next

resolution if the value is displayable in the next range

This allows the display to be used

with Mitutoyo Digimatic® products in inch mode or different resolutions other than 2

decimal places.

When the display 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.

When the measurement is greater than +

99 63/64 inches, a +100 or +200 will show in

the upper right portion of the LCD to indicate this amount must be added to the displayed

reading. ie: if the measurement is 154 5/8 inches, 54 5/8 and +100 will be displayed on

the LCD. If the measurement is -307 23/64 inches - 7 23/64 , +100 and +200 will be

displayed on the LCD.

The

Resolution

of the display can be set for

Normal;

(.01mm or .001in),

Reduced

; (.1mm

or .01in) or

Increased

; (.01mm or .0005in)

+, 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.

Offset Addition Offset addition allows the user to preset up to 3 different distances that are then added to the Digital Displays position when selected. This allows the user to quickly switch measurement modes from one reference point to another such as in the case of inside and outside measurements on ProPanel or multiple stations on a vertical panel saw. To utilize the offset addition feature, programming parameter Pr10 must be set to 1.
