User's Manual Part 5

ProScale M150, M250 and all products with General Purpose LCD Digital Displays 28 of 28
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. The
display will then flash one of “offset” numerals 1, 2, 3 or 4 located in the upper left corner
of the LCD. Offset 1 is the ABS position with no offset addition. Offset 2 is the ABS
position with parameter Pr11 (Offset Addition 1) added to it. Offsets 3 and 4 have similar
functions with parameters Pr12 and Pr13 added to the ABS position respectively.
To move from “Offset” 1 to 2, momentarily press the F1 key. Each depression of the F1
key advances to the next offset. After offset 4, the display will move back to offset 1.
(See Programming Parameters 9, 10, 11, 12 and 13. Factory default is
Disabled.
)
Limit Mode
The digital display will show either “
LL “
for Low Limit or ”
UL”
for Upper Limit if a pre-
programmed upper or lower reading is encountered. Upper and Lower limits are set with
programming parameters
Pr16
and
Pr17
but are only active if
Pr14
is set to 1. Display
toggles between current position display and "LL" or "UL". The position is shown for 2
seconds and the "
LL
" or "
UL
" is shown for 2 seconds. This continues as long as a limit
has been exceeded. Limit monitoring is always active, even in programming mode.
Numerous Programming parameters, including
Offset Addition
and
Limit mode
indicate a
‘factory default set in inches’
. The equivalent offset/limit value in mm or cm is applied if
you switch the
MODE
of display to mm or cm. ie These parameter values take on the
unit of measurement
MODE
(mm, cm or inches ) active when programming is entered.
Scaling
All General Purpose Digital Displays have the ability to “scale” the actual measurement.
This function is useful when the actual measurement must be multiplied or divided before
being displayed. Care should be taken when using this function since invoking it will
cause the unit to display a reading different than the actual measured or traversed value.
This function is set using
Programming Parameter Pr7. The Factory Default is set to
1.000 - No Scaling
Changing the Batteries
A low battery indicator will appear in the lower left corner of the LCD display when new
batteries are needed.
Surface Mount Displays
: 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 CASES ARE SCREWED TOGETHER.
Panel Mount Displays:
Remove and replace 2D batteries noting proper orientation.
