Model# 2493
Triple Function Digital Switchboard Meter
The Model 2493 (Triplefunction) Digital Switchboard Meter was developed to provide customers with a versatile AC digital power meter.
- End user programmable for CT ratios and PT ratios
- End user selectable legends Watts, kWatts and mWatts, etc.
- Non-volatile memory. If loss of power occurs, all settings will remain the same.
- Accuracy of + 0.2% of reading, + 0.1% Full Scale.
- True RMS current and voltage measuring. Most desirable if distorted sine wave is present.
- Security of settingsā¦ā¦ā¦. Complete removal of cover is required to access selectable or programmable
variables. Four push buttons are used for quick setup, except 2493 with front panel configuration. - Display averagingā¦ā¦ā¦ā¦ Programmable from 1 to 25 samples to eliminate annoying digit bounce.
- RS485 communication option allows up to 32 units to be networked together for remote reading.
- Analog output option allows ability to connect to data acquisition systems.
- Complete operating instruction manual included with each meter.
- NIST Calibrated Certificate/Test data available as an option.
- Modbus communication option allows connection to existing control systems.
