Turning Laser On
Press Power button on the keypad to turn on the PL650™. Note
the power button on the remote will not operate until the laser has been
powered up from the keypad direct, the power button on the remote then
acts as a standby button. The PL650
TM
will first have a flashing laser dot and
flashing grade numerical display, when both of these stop flashing the laser
is then level. On the bottom left of the LCD display screen is an electronic
bubble vial and an arrow indicating the direction needed to twist the PL650
Housing, within or on top of the pipe, in order to get it level left to right.
When the bubble is show in the center of the vial then it is level left to right
and will ensure maximum accuracy for the laser dot.
Setting a Grade
Setting a grade on the PL650 tilts the laser dot either up for a +ve grade
and down for a -ve grade. The grades are set as a percentage and the
maximum grade that can be set is +40.000% to -20.000%. (see page 12
for conversion chart)
The required grade is entered using the center four buttons on the key pad,
first press the “SET” button the +/- symbol is flashing, use the up down
arrow buttons to select either a +ve or -ve grade.
Press “SET” again and the first digit will flash, use the up and down
arrow keys to set the required number for this digit (leave as “0”
if required). To move to the next digit press “SET” once more and again use
the arrow keys. Once all the digits have been set to the required figure then
press “ENT” this enters the grade into the laser and it will begin to
set that grade. When the laser dot stops flashing the grade is set. Note the
PL650 remebers this grade the next time the laser is turned on.
