TRMS Digital Multimeters
Fast Acoustic Continuity Test
Testing for short circuiting and interruption is possible with the
selector switch in the
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 sym-
bols.
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.

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
The device can be remote configured, and momentary and stored
measurement data can be read out via the bidirectional infrared
interface. The
software are required to this end (see accessories). Interface
protocol and device driver software for LabVIEW
Instruments™) are available upon request.
DKD Calibration Certificate
The multimeters are furnished with an internationally valid DKD
calibration certificate (recognized by EA and ILAC). After the
specified calibration interval has elapsed (recommended interval:
1 to 3 years), the multimeters can be inexpensively recalibrated in
our own DKD calibration laboratory.
