Integral Operation Function

NOTE:
In addition to the above items, other settings (such as self-testing and date/time setting) or operations with
influence on the integral cannot be executed; otherwise, errors may be caused.
7.3 Setting of Integral Measurement Configuration
You can set the start mode, stop mode, automatic zero setting, automatic calibration, watt-hour integration, current
integration and other parameters of integral measurement. Specific steps are as follows:
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 configuration interface.
7.3.1 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. Integra-
tion 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 toman-
ually 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 max-
imum/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 inte-
gral. 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 inte-
gral 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 up-
dating cycle).
