Press the [lx ・h] switch to enter Integral illuminance mode. In this mode, Integral
illuminance and integral time appear.
・ When you select fc mode, the unit of fc・h is used in integral illuminance mode.
Start of integration
Push the [lx・h] switch to shift to the lx・h mode.
Push the [INV.] switch.

Example: Irradiation 1388lx Example: Integration time one hour
・ The display alternately shows the integral illuminance and integration time at 2-
・ Even after switching to another measurement mode, the integration is
continued. If the [lx・h] switch is pushed again, then an integral illuminance is
・ It is not possible to change the C.C.F. value during integration.
