Using The Instrument - CST/BERGER SAL20N Instruction Manual

INTRODUCTION
Thank You for purchasing one of our Automatic Levels.
This manual includes specifications for the PAL and SAL"N" series auto
level. This instrument was carefully inspected and calibrated within tight tol-
erances before shipment. We properly package the instruments for ship-
ment, but we cannot control how the package is handled during shipment.
We advise that you check the instrument using the test shown in the Chapter
"Line-of-Sight" before using. "Measure Twice, Cut Once"...
After doing any job using any instrument, it is advised that you check your
work. To check your work, set up the instrument in a different location from
the place where you originally set up (approx. 16 m) and reshoot a few of
your original targets. The new readings should agree with the first readings.
If the new readings do not agree, you should have the instrument checked
by a CST/berger Authorized Repair Center, or try the Line-of-sight adjust-
ment.
