1. Safety instructions
The measurement amplifier U conforms to all
safety regulations for electrical measuring, con-
trol, monitoring and laboratory equipment, as
specified under DIN EN 61010, Section 1, and the
equipment has been designed to meet protection
class I. It is intended for operation in a dry environ-
ment, suitable for the operation of electrical equip-
ment and systems.
Safe operation of the equipment is guaranteed,
provided it is used correctly. However, there is
no guarantee of safety if the equipment is used
in an improper or careless manner.
If it may be assumed for any reason that non-haz-
ardous operation will not be possible (e.g. visible
damage), the equipment should be switched off
immediately and secured against any unintended
use.
In schools and other educational institutions,
the operation of the measurement amplifier must
be supervised by qualified personnel.

The measurement amplifier U is designed for
amplifying low-amplitude measurement signals
from sources with low input impedance. Com-
pensation of offset voltages is accomplished by
fine and coarse offset adjustment knobs. The
amplification itself can be selected from 0 to 5
powers of ten. High-frequency noise or other in-
terference signals are suppressed by means of
a low-pass filter with time constants between 0
and 3 s. ´The amplified input voltage is output
as a signal in the range -12 ... +12 V with the
same sign as the input.
Any voltmeter or an oscilloscope can be con-
nected to the measurement amplifier output.
