Measurement Specifications
- Voltage Measurement
- True RMS
- Accuracy <1%
- Resolution in float (32 bits)
- Frequency Measurement
- Accuracy <1%
- Resolution in float (32 bits)
- Current Measurement
- True RMS
- Accuracy 0.1% (dynamic range 1000:1)
- Depends on accuracy of current clamp connected
- Resolution in float (32 bits)
- Power Measurement
- Accuracy 0.1% (dynamic range 4000:1)
- Depends on accuracy of current clamp connected
- Resolution in float (32 bits)
- Accuracy 0.1% (dynamic range 4000:1)
- Energy Measurement
- per current channel
- resolution integer (32 bits) for Wh
- can be reset
- Voltage Samples per channel (1 period)
- Updated 1Hz
- sampled at 4096Hz (80 samples for 50Hz)
- Resolution in float (32 bits)
- Current Samples per channel(1 period)
- Updated 1Hz
- sampled at 4096Hz (ex. 80 samples for 50Hz)
- Resolution in float (32 bits)
- Voltage frequency samples
- Updated 1Hz
- DC - 20th harmonic
- Resolution in float (32 bits)
- Current frequency samples per channel
- Updated 1Hz
- DC - 20th harmonic
- reference on matching voltage rising zero cross
- Resolution in float (32 bits)
- Current Factor can be set for different current clamps
- ex. current clamp of 5A or 5000A can be connected.
- if a very big current clamp is used, the energy measurement can overflow faster.
Hardware
