Measuring range switch
The multimeter has only one rotary switch by which all the mea-
suring ranges are selected. The meter can be switched from the
direct voltage ranges to the corresponding alternating voltage
ranges, or from the direct current ranges to the corresponding
alternating current ranges, without switching off the measured
value.
It must be ensured that the measuring range switch is
first set to
the highest measuring range
when measuring voltage and current.
The switch then has to be switched to lower ranges until the
optimum deflection is obtained.
Connection sockets
The meter has connection sockets with shock-proof protection.
Their functions are as follows:
Socket „
⊥
“
= common connection for all measuring ranges
(instrument earth)
Socket „+15 A
= METRA HIT 2A: connection for highest
current measuring range 15 A
Socket „
Ω
“
= connection for resistance measurement and
capacitance measurement (negative poten-
tial)
Socket „+V,A
“
=
connection for all voltage and current ranges
except for METRA HIT 2A: here up to 1.5 A
The sockets can accommodate the instrument leads with shock-pro-
tected connection plugs as well as all measuring cables with banana
plugs (diameter 4 mm).
