7.3 Description of Storage Function
Storage items
Storage items include all conventional measurement data, harmonic measurement data (when the harmonic measurement
data display is turned on), operation data, integral data and frequency (voltage and current). When the harmonic data
display is turned off, the harmonic data will not be stored.
When the maximum hold function is turned on, the display values of U (voltage), I (current), P (active power), S (apparent
power), Q (reactive power), U+pk/U-pk (voltage peak), I+pk/I-pk (current peak) and P+pk/P-pk (power peak) will hold the
maximum values. The stored measurement data also holds the maximum value.
When the storage is running, if the "Hold" key is pressed to hold the display, the measurement operation and the storage
interval time count will be held (paused), and the data storage will also be held (paused). Press the Hold key again to keep
the storage running.
Storage limitations
When the storage is being executed, the following settings cannot be made: measurement mode, wiring mode, measurement
range, peak factor, synchronous source setting, input filter, data update rate, number of harmonic measurement, operational
formula of harmonic measurement distortion rate, PLL source setting, storage time interval setting and zero setting.
Functions cannot be executed: proportion function setting, average function setting, BIT operation, Math operation function,
zero level compensation function, configuration file saving and loading function.
