CHAPTER 7. INTEGRAL OPERATION FUNCTION
39
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 Effective value; mn Calibration to the average rectified value of
the effective value.
dc Simple averaging;
rmn Average rectified value; ac
AC component

Integration
When the integral measurement function is enabled, you can keep the current integral information and carry out
the following operations: exit, start and stop. Specific steps are as follows: Operation steps
1.
Press “Integ” to enter the integral display interface.
2.
In the integral measurement display interface Press the soft key corresponding to the “START” parameter to
start or recover integral operation. The Start status and integral operation value are displayed in the
interface.
3.
When you need to keep the current integral status and integral result, you can press the soft key
corresponding to the “RUN HOLD” parameter. Then the current status of the integral result display and
communication output will be kept no matter whether integral operation is running.
4.
When you need to continue to implement integral operation, double-press the soft key corresponding to the
“RUN HOLD” parameter to exit the HOLD status. The power meter will display the integr
al result after exiting
the HOLD status. The schematic diagram of display of the HOLD/RUN integral result is shown below.
5.
When you need to suspend integral operation, press the soft key corresponding to the “Stop” parameter to
suspend integral operation.
6.
Press the soft key corresponding to the “RESET” parameter to reset the integral value and integral time. The
relationship diagram of start, suspension and resetting of the integral operation status is shown below.
Auto Clear when ON is selected.
Auto Clear when OFF is selected.
