Applications
The METRA MAX 12 digital multimeter is suited for universal, gen-
eral applications in the electrical and electronics fields, as well as
in radio and television service, training and education.
It is of especially flat design, and thus fits into any bag. The pro-
tective cover with tilt stand, which is included as a standard fea-
ture, provides for easy transport, allows for convenient reading
from the workbench as well as for attachment of the measuring
probe to the instrument.
Selection of input resistance for voltage measurement
In addition to the usual voltage input with one resistance value of
10 MΩ, which is selected via V
provides the electrician with an additional selector switch position
for V with an input resistance of approx. 400 kΩ. This allows
400kΩ
for the avoidance of negative influences from capacitive coupling
during voltage measurements in power supply systems.
Automatic/manual measuring range selection
The measurement quantities are chosen with the rotary selector
switch. The measuring range is automatically adapted to the mea-
surement value. The measuring range can also be manually
selected with the AUTO/MAN button.
Overload warning
An acoustic signal occurs, if the range limit value is exceeded.

Hold/Min/Max
By pressing the HOLD/ON key, the currently displayed measure-
ment value can be „frozen" in the display.
The minimum and maximum values which were present at the
input of the measuring instrument after activation of the MIN/
MAX mode can be selectively "retained" with the MIN/ MAX func-
tion. The most important application is the determination of the
minimum or maximum value during long-term observation of
measurement quantities. MIN/MAX has no effect on the analog
display; it continues to display the current measurement value.
Diode and continuity testing
This provides for the testing of the polarity of diodes, as well as
inspection for short-circuits and circuit interruptions. In addition to
the display, resistances of less than 40 Ω are indicated with an
acoustic signal.
Protective cover for rough operating conditions
A protective cover of ABS with a built-in stand protects the instru-
ment against jolts and falls. It also secures the test prod for one-
hand operation, and allows for winding of the measurement cable
which provides protection during transport.
Theft protection
Company name and name of the user can be entered into the
field next to the display with an indelible etching needle for identifi-
cation of the owner.
