Power Meter-Logger is a meter that is capable of not only measuring and displaying thirty-six electrical parameters but has the capability to log and store 1000 sets of five important parameters in internal memory. Facility to increase data logging facility for more than 1000 records is available on request. The recording interval is normally one hour but can be changed upon prior request. Any variation in load by more than 20 per cent is also recorded. The meter is provided with communication port and appropriate software for accessing recorded data. CT/PT ratio is programmable. Facility to calibrate voltage, current and Power factor of individual phase is provided through Keyboard and Display. Password is user-programmable.
The meter is available in two versions: with LCD and with Seven-segment LED display.
Measures True RMS with Data Logging.

Special Features:
-
Measurement of 36 electrical parameters,
-
Recording of five critical parameters at predetermined interval,
-
Facility for uploading of data for system analysis and corrective actions,
-
Eminently suitable for captive power generation, supply of power to grid, and a host of applications.
Recorded
data can be uploaded in PC or Laptop Computer through the communication
port RS 232 or RS 485 MODBUS-RTU protocol. RS 232 cable is provided for
retrieval of recorded data for RS 232 model only. Display and
calibration of parameters such as Voltage (0-415 Volts without external
PT and 0-440 KV with external PT), Current 0-5 A without external CT,
Frequency, Date and Time can be done with PC based GUI. Parameters like
Power Factor per phase and Instantaneous Power per phase are displayed
in the GUI. Facility to nullify the residual data related to current
per phase can also be done through GUI. The product is supplied with
operating GUI
Precaution:
Only
authorized persons should perform the Administration mode and Residual
mode of operation to ensure integrity of entered data.
