1. Normal Recording mode ●Sampling period and RMS calculation Sampling the inputs at every 1.6ms/CH and calculate the measured value (RMS) at every 100ms. The Peak value (crest value in sampling data) will be updated and kept. ●Recording Average of the measured value is recorded at every recording interval. RMS measured values, Max, Min and Peak values (sampled crest value converted to sine RMS value) are recorded at every 10 times of recording.
2. Trigger Recording mode ●Detection and RMS value calculation Sampling the inputs at every 1.6ms and comparing the Peak value (sampled crest value converted to sine RMS value) and Detection level. For current, when the Peak value exceeds the level and for voltage when the Peak value is below the level; detection is triggered. RMS value is calculated at every 100ms. ●Recording When the Detection level is exceeded, 8 data (for about 0.

For voltage values, Trigger is detected when it is below the detection level.
3. Capture Recording mode ●Detection and RMS value calculation Sampling the inputs at every 0.55ms only at CH1 and comparing the Peak value (sampled crest value converted to sine RMS value) and Detection level. For current, when the Peak value exceeds the level and for voltage when the Peak value is below the level; detection is triggered. RMS value is calculated at every 100ms.
4. Power Quality Analysis Mode (only 5020) ●Detection and RMS value calculation Sampling the inputs at every 0.55ms only at CH1 and comparing the Peak value (sampled crest value converted to sine RMS value) at every 10ms and preset value to detect swell, dip and short interruption in power supply. RMS value is calculated at every 100ms. ●Recording When swell, dip or short interruption is detected, the detected value is recorded as Start (S) with time and date information.
