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.
