Measurement - Gossen MetraWatt METRAFLEX 300MXBL Mode D'emploi

_______________________________________________________________
An accurate measurement is assured under the following
conditions:
– The conductor is centred within the measuring head.
– The measuring head forms a perfect circle.
– The probe coupling is not located close to other conductors
carrying high current.

MEASUREMENT

To activate unit, move the rotary switch from the "off" position to
the required measuring range.
measured is unknown, first select the highest range and then
reduce accordingly.
The red and the orange LED might flash when the unit is
switched on or when the measuring range is changed.
To obtain correct results set the scaling factor on the meter or
analyser for each measurement channel corresponding to the
selected measuring range; see table under SPECIFICATIONS.
When measuring active power you also must observe the
direction of the current flowing through the measuring head.
Check the correct polarity at the power analyzers based on the
vector representation of voltage and current, or by the polarity of
the values for active power. These have to be positive for
consumer measurements.
