Remarks
The channels of the measurement ranges are automatic. To define the measurement range in
manual mode, press the key opposite.
A long press on the key of the channel is used to return to automatic mode. In addition:

in automatic mode, the measurement range on the screen is highlighted in the colour of the
channel

in manual mode, it is not.
The coupling of the channels can be modified using the key opposite:
DC  AC  AC <5kHz  AC <625kHz  AC+DC  AC+DC <5kHz  AC+DC <625kHz
6.3 Power measurement
To measure power, you must have the right Probix accessories:
 current measurements are made using HX0034, HX0072, and HX0073 clamps
 voltage measurements are made using the HX0033 banana adapter and leads.
A power measurement is made in the Multimeter mode, by clicking the icon. Then, select the type of set-up you want
to measure:
Single-phase power
Display of the result of calculation of the active power, measured
using CH1 for the voltage measurement and CH4 for the current
measurement.
Three-phase power
on balanced network
without neutral
The value displayed is the active three-phase power calculated from
the wiring proposed at the time of selection.
Three-phase power
on balanced network
with neutral
The value displayed is equal to 3 times the active power measured on
one phase.
Three-phase power,
3 wires
Display of the result of calculation of the active three-phase power
measured by the two-wattmeter method on a installation without
neutral.
When the values are read in this mode, the following screen is displayed:
 Example: Single-phase power
 Channel 1 indicates the voltage measured
directly with its min and max values
 Channel 4 indicates the current measured
directly with its min and max values.
 The various power values calculated from
channels 1 and 4 are displayed, along with
their power factor.
 The type of wiring is indicated next to the
values.
