3.6 PERCENT MEASUREMENT (% MODE)
Push the [%] switch to enter the % mode, the readout shows the ratio of the
measured illuminance value to the reference illuminance value.
(Example: The deviation is expressed as 90%)
Percent = ((C.C.F. x Illuminance) / reference illuminance value) 100
How to enter the reference value (on the basis of measurements)
Push the [lx] switch to enter the lx mode, and measure illuminance for reference
When the measured value on the display becomes stable, push the hold switch to ON
to fix the display.
Push the [SET] switch to enter the measured value as the reference illuminance
Push the hold switch to OFF.
Push the [%] switch to shift to the % mode.
How to enter the reference value (setting a given value as standard)
Push the [%] switch to shift to % mode.
Enter a numerical value and push the [SET] switch to activate the standard value.
・ The entry value range is from 0.001 to 999900.
・ If the value 0 is entered as the standard value, a code E7 appears.
・ The set value is hereafter held until the reference value is changed or the power
switch is turned off.
・ The reference illuminance data is deleted after turning off.
