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 180Oto
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 “”simultaneouslyfor3seconds;whenmodeindicatorblinks,
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 “”simultaneouslyto
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
leveling of instrument starts up. (2) Press the Key “ ” and “ ” simulta-
neously for 3 seconds. When undervoltage indicator blinks, the instru-
ment enters mode of adjusting. (3) Press the Key “ ” or “”ofX-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.
The PLS HVR 505 should be checked, like all measuring instruments,
before use. Set the PLS HVR 505 on a stable surface - Method A.
Turn the laser on and let it level. Mount the PLS HVD 505 Detector
at a fixed distance, e.g. at 90 feet, and move it onto the laser plane.
Now turn the instrument around to each 90° point and let the instru-
ment level. In each case, measure the difference to the first height.
If the deviation is smaller than 1/8 inch, the instrument is within the
specification. In the case of larger deviations the instrument has to
be calibrated.

Caution ! The automatic leveling is
switched off in manual mode. If the
instrument gets moved it will not turn
off. In the semi-manual mode the tilt
control is active only in X direction. We
recommend using a second detector
to control the sloped plane.
Vertical Use
The PLS HVR 505 has third
leveling axis (z-axis). Place the
instrument as shown. The plumb
beam will be leveled automatically.
The turning rotor head projects an
upright plane to the plumb beam at
an angle of 90°. To adjust the align-
ment line use the arrow keys to
move the laser beam right and left.
Right angles can then be measured simply and quickly.
..........................
The PLS HVR 505 may be used with the PLS RC 505 infrared
remote control. Point the remote in the direction of the PLS HVR
505 for remote operation. Remote distance is 70 feet indoors and
40 feet outdoors. There are 9 keys on the panel of the remote unit.
The remote panel matches the keypad of the PLS HVR 505.
Pressing any key will make the indicator lamp blink once indicating
remote signal is being sent.
