CHECKING CALIBRATION
A. Instrument Checking - Method B
(1) Place the instrument at the point of 90 feet in front of wall (or set a
scaleplate at the point of 90 feet away from the instrument), and then
adjust the level of the base approximately to aim the X1 to the wall (or
scaleplate) as depicted at right.
(2) After switching on the
power, use the detector
measuring the h1 of X1-
beam on the wall or scale-
plate. (3) Loosen the screw
of the tripod and then turn
the instrument 180 to
O
measure the h2 of X2-beam
on the wall or scaleplate.
D-value between h1 and h2 ought to be less than 1/8 inch.
(4) Check the Y-beam in the same way.
B. Level Adjusting
If the D-value between h1 and h2 is more than 1/8 inch, adjust the
instruments according to the following steps:
1. Y-axis adjustment. (1) Press the Key ON/OFF when power indicator
lights & automatic leveling of the instrument starts up. (2) Press the key
" " and " " simultaneously for 3 seconds; when mode indicator blinks,
the instrument enters mode of adjusting. (3) Press the key
" " or " " of Y-axis repeatedly and check the position of laser beam
when mode indicator is blinking until the D-value between h1 and h2 is
less than 1/8 inch. (4) Press the Key "
" and " " simultaneously to
hold the adjustment until mode indicator goes out. If the instrument is
set horizontally, Y-axis adjustment stands for Z-axis adjustment.
C. X-axis Adjustment
(1) Press the Key ON/OFF when power indicator lights & automatic lev-
eling of instrument starts up. (2) Press the Key " " and "
" simultane-
ously for 3 seconds. When undervoltage indicator blinks, the instrument
enters mode of adjusting. (3) Press the Key " " or " " of X-axis
repeatedly and check the position of laser beam while undervoltage
indicator is blinking till D-value between h1 and h2 is less than 1/8 inch.
(4) Press the Key " " and " " simultaneously to hold the adjustment
until undervoltage indicator goes out. If canceling the adjustment,
please shut off the instrument and then turn it on. If the adjusting range
exceeds range permitted, the power indicator will flash.
Notice: Once the D-value exceeds the error range that instrument
permits, please contract the supplier to repair the instrument.
D. Plumb Point Check
(1) Place the instrument between two walls with distance of 90 feet.
(2) Place the instrument on its side and then adjust. (3) Switch on the
power, and then measure the middle point of the laser beam on the
wall: hA, hB and hA', hB'.
(4) 1=hA-hA', 2=hB-hB'. D-value between 1 and 2 ought to be
less than 1/8 inch.
E. Adjusting If-D value between 1 and 2 is more than 1/8 inch,
adjust the instrument according to procedure described in B.
