| Programmable voltage meters |
| 1.General |
 |
| The PZ series programmable voltage meters are the kind of smart electric meters. It can measure electric network voltage accurately (include phase voltage and line voltage). With 4 keys on the front panel, we can set the parameters according to users' need, or we can switch the voltage of different phases. At the same time, we can transfer the measure data with the options of analog output, relay output or digital output (RS485). And they have different sizes suitable to all the measurement place. |
