10.4-inch LCD touch color screen, multi-power intuitive display, full touch screen operation, more convenient operation.

The folding foot can raise the instrument by about 15° for optimal operation and reading view.

S/N

Function

Three-phase current fast connection terminal: the primary wiring can achieve a wide range of 0.2 mA ~120 A current measurement.

Three-phase voltage terminal: primary wiring can achieve voltage measurement of 6 V ~528 V.

Rich communication interface: including RS232, USB, LAN, easy for users to set up an automatic test system.

Shell ground: Make that the casing ground is reliably grounded before use.

Power interface: AC 220V power input interface with switch and safety pipe.

Pulse input terminal: from left to right, photoelectric pulse, electric energy pulse, synchronous signal and clock pulse PPS.

Pulse output terminal: from left to right is the electric energy pulse FL/ FH, Synchronous signal, clock pulse PPS 2.

Epitope difference / magnetic field measurement: it is used to measure the magnetic field in the 3 D magnetic field sensor; in the epitope difference sensor, it can measure the potential difference between the same phase voltage terminals of the multi-epitope device.

Temperature and humidity measurement: the temperature and humidity sensor is used to measure the temperature and humidity of the site.

• Each phase is equipped with a pair of fast terminals and wires, and the ac current of 0.2 mA ~120 A can be measured by direct connection, simplifying the wiring operation.

• Fully automatic switching range, the transformer does not shift at one time, no matter in which range suddenly into the large current will not lead to damage or measurement accuracy reduction

• The minimum measurement is limited to 0.2 mA, which can assess the accuracy and stability of the power / electric power of the R46 electric power device and its standard meter at the minimum starting current of 0.3 mA.

• There is complete electrical isolation between the voltage and current measurement circuits; in the limit state (500 V, 100 A), it will not damage the instrument, and can ensure the accurate value.
