| 1.General |
 |
| The PZ series programmable frequency meters can measure electrical network frequency accurately. With 4 keys on the front panel, we can set the measurement parameters. And we can transmit the measure data with the options of analog output or digital output (RS485). With logic input or logic output, we can realize controlling other equipment remotely . |
