Automatic or Manual Measuring Range Selection
Measured quantities are selected by means of a rotary switch and
a function key. The measuring range is automatically matched to
the measured values. The measuring range can also be selected
and fixed manually with a key.
Fast Acoustic Continuity Test
Testing for short circuiting and interruption is possible with the
selector switch in the position. The threshold value for
acoustic signaling can be set to 1, 10, 20, 30, 40 or 90 Ω.
Automatic Storage of Measured Values *
The DATA function automatically saves the digitally displayed
measured value after settling in. Acoustic signaling is also used to
indicate whether the new measured value deviates from the initial
reference value by less or more than 0.1% of the measuring
range.
* Patented
Storage of Min-Max Values
Comparable to the slave-pointer function of an analog instrument,
the device saves the highest and lowest measured values after
the MIN/MAX function has been activated or reset. These
extreme values can be queried at the display.
Battery Charging Status – Power Saving Circuit
The battery charging status is indicated by means of four symbols.
The device is switched off automatically if the measured value
remains unchanged for a period of between 10 and 59 minutes
(adjustable), and if none of the controls are activated during this time.
Automatic shutdown can be deactivated by switching the
instrument to continuous operation.
METRAHIT⏐X-TRA⏐OUTDOOR: The infrared interface can be switched
off in the standby mode.
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 and test
probe holder. The rubber material also assures that the instrument
does not wander if it is set up on a vibrating
surface.
Infrared Data Interface with METRAHIT⏐X-TRA⏐OUTDOOR
The device can be remote configured, and momentary and stored
measurement data can be read out via the bidirectional infrared
interface. The USB⏐X-TRA interface adapter and METRAwin 10 soft-
ware are required to this end (see accessories). Interface
protocol and device driver software for LabVIEW
®
(National
Instruments™) are available upon request.
DKD Calibration Certificate
The multimeters are furnished with an internationally valid DKD
calibration certificate (recognized by EA and ILAC). A
fter the
specified calibration interval has elapsed (recommended interval:
1 to 3 years), the multimeters can be inexpensively recalibrated in
our own DKD calibration laboratory.
