1. Safety instructions
The microvoltmeter conforms to all safety regula-
tions for electrical measuring, control, 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 in-
tended for operation in a dry environment, suit-
able for the operation of electrical equipment 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-
hazardous operation will not be possible (e.g. visi-
ble damage), the equipment should be switched off
immediately and secured against any unintended
use.
In schools and other educational institutions, the
operation of the microvoltmeter unit must be su-
pervised by qualified personnel.
• Before using the microvoltmeter for the first
time, confirm that the specifications printed
on the rear side of the housing are compatible
with the local mains voltage.
• Before using the microvoltmeter for the first
time, check the housing and the mains lead for
any damage. In the event of any malfunc-
tion/operational defect or visible damage,
switch off the unit immediately and secure it
against unintended use.
• The instrument may only be connected to the
mains via a socket that has an earth connec-
tion.
• Before making any connections, check the
experiment leads for damaged insulation and
exposed wires.
• The equipment may only be opened/repaired
by qualified and trained personnel.
