PRODUCT DESCRIPTION
The Z203-2 is a complete single-phase network analyzer, suitable for voltage ranges up to 500 Vac, with currents
up to 5 A (from 35 Hz to 75 Hz). The instrument can supply all the following electrical quantities: Vrms, Irms, Watt,
Var, Frequency, Energy, Cos
ɸ
. The measurements are made available for reading via serial communication both
in floating point format and normalized (except for energy). By setting the Dip Switches or the Modbus registers,
the analogue retransmission of any of the Vrms, Irms, Watt, Var, Frequency and Cos
ɸ
quantities is possible.
USB
