CHAPTER 8. INTEGRAL OPERATION FUNCTION 40
1. Press “Integ” to enter the integral measurement interface.
2. Press the soft key corresponding to the “SETUP” parameter in the integral measurement interface to
enter the integral parameter conguration interface.
8.4.1 Parameter descriptions:
Start set in the MANUAL mode or TIME mode via the right soft key.
MANUAL press the “START” soft key in the integral measurement interface in the manual start mode to
trigger the manual start of the integral function.
TIME: the date on which the integral mode is started can be set in the real-time start mode. Integration will
be started on the set date. When the time/date combination is set in the real-time start mode, integration
will not be started before the current time and date. Integration will be started when the screen is
updated once at least before the start time.
Stop: set in the MANUAL mode, TIME mode and TINTerval mode via the right soft key.
MANUAL: press the “STOP” soft key in theintegral measurement interface in the manual stop mode
tomanually stop integration. When the integration time reaches the maximum integration time (10,000
hours) or the integral value reaches the maximum/minimum display value, integration will be stopped,
and the current integral time and integral value will be kept.
TIME The date for stop of the integral mode can be set in the real-time stop mode. Integration will be stopped
on the set date. When it reaches the set time or the integral value reaches the maximum/minimum display
integral value, integration will be stopped, and the current integral time and integral value will be kept.
TINTerval the integral measurement time can be set in the set-time stop mode. When it reaches the set
ending date and time or the integral value reaches the maximum/minimum display integral value,
integration will be stopped, and the current integral time and integral value will be kept.
Auto Clear used for enabling (ON) or disabling (OFF) the function of automatic zero clearing of the integral.
On: integration is restarted when the START button is pressed to start integration. OFF: integration is
restarted based on the integral value at the end of previous integration when the START button is pressed
to start integration.
Auto Cal used for enabling (ON) or disabling (OFF) the function of automatic integral calibration. When
automatic integral calibration is enabled, zero setting is implemented. In this case, the power and current
measured just now are subject to integration.
WP type used for selecting the integral mode for positive and negative watt hours. There are four integral
modes:
Charge/Discharge: used for measuring the DC positive and negative watt hours (integration of sampling data).
Sold/Bought used for measuring the AC positive and negative watt hours (value integration in each data
updating cycle).
q type used for selecting the current integration mode. Options of the current integration mode are as follows:
rms Eective value;
mn Calibration to the average rectied value of the eective value.
dc Simple averaging;
rmn Average rectied value;
ac AC component
