3.3 Integration

The PW3335’s integration function can operate in either of two modes: fixed-range integration mode or auto-
range integration mode.
Fixed-range integration mode
Integration operation uses the set measurement range. (When auto-range operation is enabled, integration is
fixed to the range in effect at the start of operation.)
Auto-range integration mode
Integration operation is performed while the measurement range is controlled through auto-range operation.
In this mode, the voltage range is fixed at the start of integration, but the current range is determined using
auto-range operation between the 200 mA range and the 20 A range. This capability allows auto-range oper-
ation to be used in applications characterized by large changes in current or power, for example when mea-
suring the sequence of operations of a household electronic device as it switches from the standby state to
the normal operating state. Additionally, since not only the last integrated value, but also integrated values for
each range that was used during integration operation can be displayed when integration is in the stopped
state, operators can assess integrated values for each state of the measurement target (for example, standby
and normal operation) after a single integration measurement session. Furthermore, auto-range integration
can be used in combination with the range select function to shorten the switching time between ranges,
allowing more efficient integration measurement.
