Step 4 Calibration
Calibrating the readout will set the
device to display the exact distance from
the bed of the planer to the tips of the
planer blades and show the actual final
thickness of a board that will come out
the back of the planer. Take a flat board
and run it through the planer, make sure
the planer is removing material from the
top of the board (18). After the final pass
through the planer turn it off and unplug
it. Do not touch the height adjustment
crank. If the planer has a head lock leave
it locked.
Turn on your digital readout and be
sure it is in the ABS mode. It does not
matter if the display mode is MM or IN.
Lift up on the tab on top of the steel
scale and slide the scale upward so that
the piece of wood you just planed can fit
between the bottom of the scale and the
flat contact surface of the frame (19). Do
not use the first 2 or 3 inches of the end
of the board as this may contain a small
amount of snipe that could effect the
calibration.
Push the ON/OFF--CAL button and hold
it for 3 or 4 seconds (20). The display
will now read 0.000. Remove the board
and allow the scale to come back down
and contact the flat surface of the frame.
The readout will now display a number.
This number is the exact thickness of the
board you just planed and your readout
is now calibrated. It will always
maintain this calibration and will not
need re-calibrated unless the battery is
removed or goes dead or the planer
blades are changed or wear
considerably.
Note : Wood chips between the bottom
of the scale and the frame or a board
can throw off the readings.
