Integration stop
1
If the instrument is in other than the lxh mode, push the [lxh] switch to shift to the
lxh mode.
2
Push the [INV.] switch, and then push the [START/STOP] switch to stop integration.
The value of integral illuminance until stop integration show after stop
measurement.
To check the integral illuminance and integration times by the time measuring
stop, push the hold switch to ON. The integral illuminance and integral time
appear alternately for a half second each.
Push the [INV] switch and [START/STOP] switch, and then the IM-600 will start
integration from 0 lxh and 0 second.
Even when the mode changes to another mode after integration stops,
integral illuminance and integral time are displayed after selecting [lxh] mode
again and push the HOLD switch to ON. Both integral illuminance and
integration time are alternately displayed at 1 sec. intervals.
Range of integration
The maximum indication of integral illuminance is 1,000,000,000 lxh and values
over 999900 lxh are expressed using exponents. The upper limit of the integration
time is 9999 hours.
Example: Integral illuminance 10,000,000 lxh
When integral illuminance values exceed the upper limit, a code E5 appears.
When integral time values exceed the upper limit, a code E6 appears.
If you measure the integral illuminance for a long time, we recommend you use
AC adapter.
Suspension of integral illuminance measurement
If the HOLD switch is turned On during the integral illuminance measurement, the
integration will stop, then the value of integral illuminance and integration time until
the time when integration stop is alternately displayed at 1 second intervals.
If the HOLD switch is turned OFF, integral illuminance measurement resumes.
