Unpacking - Repacking
All the equipment was checked mechanically and electronically before shipment.
Every precaution was taken to ensure that you receive the instrument undamaged.
It is a good idea however to check quickly to detect any damage that may have occurred
during transport.
If there is any damage, immediately notify the transporter of the customary reservations.
Caution!
If you ship this instrument on elsewhere, use preferably the original
packaging and indicate the reasons for reshipment as clearly as possible
in a note enclosed with the equipment.

DESCRIPTION OF THE INSTRUMENT
The PX 110 and PX 120 wattmeters
can be used to measure AC and DC power levels,
voltages and currents. They have been designed specifically for general and technical colleges,
installers and maintenance departments.
The PX 110 is a single-phase only wattmeter, while the PX 120 provides the possibility of
measuring three-phase power levels, but only three-phase with 3 balanced wires (T3FE);
both models enable measurement in all four quadrants.
These wattmeters give priority to reliability, robustness, safety, simplicity of use and rapidity
of implementation (automatic range change).
The two models have a two-way communication interface (optical head).
The two models measure:
- AC voltages from 500 mV to 600 V rms,
- DC voltages from 500 mV to 600 V,
- AC currents from 10 mA to 10 A,
- DC currents from 10 mA to 10 A,
- DC power levels up to 6 kW,
- AC active power levels up to 6 kW,
- AC reactive power levels up to 6 kVAR,
- AC apparent power levels up to 6 kVA
- the power factor.
The measurement range concerning the fundamental frequency is 40 to 70 Hz.
The bandwidth is 1 kHz (harmonics).
The AC and DC components are not dissociable (RMS values).
