Features

Automatic Blocking Sockets (ABS) *

Automatic blocking sockets prevent incorrect connection of
measurement cables and inadvertent selection of the wrong
measured quantity. 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. The
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 zero­frequency quantities, allowing for observation of measured
quantity fluctuation around the zero-point.

Storage of Measured Values

By pressing the HOLD/MIN/MAX key, the currently displayed
measurement 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 function.
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.

Continuity Test

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 15 minutes, and
if none of the controls are activated during this time. Automatic
shutdown can be deactivated.

Protective Cover for Harsh Conditions

The instrument is protected against damage in the event of
impacts or dropping by means of a soft rubber cover with tilt
stand. The rubber material also assures that the instrument does
not wander if it is set up on a vibrating surface.

Duty Cycle Measurement – Square-Wave Signals

This function makes it possible to test circuits and transmission
cables by measuring the frequency and the duty cycle of pulses.
