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 is deactivated for power and energy
measurement as well as for power quality analysis).
Automatic shutdown can be disabled by switching the instrument
to continuous operation.
The standby mode for the infrared interface 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
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
The device can be remote configured, and momentary and saved
measurement data can be read out via the bidirectional infrared
interface. The USB X-TRA interface adapter and METRAwin 10
software are required to this end (see accessories). An interface
protocol and device drivers for LabVIEW® (National Instru-
ments™) are available upon request.
DKD Calibration Certificate
Each multimeter is individually adjusted, subjected to final inspec-
tion and calibrated. Adherence to the specification is confirmed
by means of the included DKD calibration certificate, which is
valid worldwide (recognized by EA and ILAC). After the specified
calibration interval has elapsed (recommended interval: 1 to 3
years), the multimeters can be recalibrated at any time in our own
DKD calibration laboratory.
