Sockets (ABS) *
Automatic blocking sockets prevent incorrect connection of
measurement cables and inadvertent selection of the wrong measured
This significantly reduces danger to the user, the instrument and
the system under test, and eliminates it entirely in many cases.
Automatic / Manual Measuring Range Selection
Measured quantities are selected with the rotary switch.
measuring range is automatically matched to measured values.
The measuring range can be selected manually as well with the help
of the AUTO/MAN key.
Display of Negative
Values at the Analog Scale
Negative values are also displayed at the analog scale for zero
frequency quantities, allowing for observation of measured quantity
fluctuation around the zero-point.
Storage of min-max
In addition to displaying the current measured value, the
minimum or maximum value can be continuously refreshed and saved.
Automatic Storage of
Measured Values *
The data hold function allows for storage of the digitally
displayed measured value.
A patented process assures that random values are not saved to
memory in the case of rapidly changing measured quantities, but
rather the actual measured value.
The stored measured value appears at the digital display.
The analog display continues to read out the current measured value.
Allows for the detection of short-circuits and interrupted
conductors. In addition to displaying test results, an acoustic
signal can also be generated if desired.
Power Saving Circuit
The device is switched off automatically if the measured value
remains unchanged for a period of approximately 10 minutes, and if
none of the controls are activated during this time.
Automatic shutdown can be deactivated.
Protective Cover for
The instrument is protected against damage in the event of
impacts or dropping by means of a soft rubber cover with tilt
The rubber material also assures that the instrument does not wander
if it is set up on a vibrating surface.
METRAwin.10/METRAHit. Software (optional)
The METRAHit ONE Plus multimeter is equipped with a serial IR
interface, by means of which measured values, control settings and
device type can be transmitted to a PC using a data frame.
These values are transmitted in an electrically isolated fashion
through the housing to a plug-in interface using infrared light.
