Integral Operation Function
Access the integration function by pressing the “Integ” button. This function integrates power and current measurements
over time to generate measurements in producing (sold) or consuming (buying) directions.
The 5335B power meter can be used for integral operation of the current and power of the input unit. Technical indicators
can be calculated. In addition, the range can be switched automatically in the Buy and Sell modes according to the input
level so as to accurately complete integrate measurement.
During operation of the air-conditioner, refrigerator, induction cook and other household appliances, the working status
will change frequently, resulting in changes of the working current in a large scale. The current may decrease of dozens
of amperes to a few milliamperes. Ordinary power measuring instruments can only be used for integral measurement
within one range. If the measured value exceeds the current maximum range, the measurement result is inaccurate. You
need to manually switch the range before integral measurement. Integral measurement of equipment subject to large
current changes cannot be performed continuously. The BK5335B power meter can automatically switch the range in
the integral mode. Therefore, errors of integral measurement caused by manual range switching can be eliminated, and
the power consumption of household appliances can be measured more accurately. See the schematic diagram below.
