RANGE
key to switch manual range; its range is fixed to the
currently executing range. This causes [R-H] to appear.
2. Each time this key is pressed, the range becomes maximized subse-
quently. After the display reaches the most significant range, it returns
to the least significant range, and repeats such action.
Note: To confirm the range, cover the light-detecting surface with the cap to
make the luminous intensity zero.
3. When the display shows the setting range, stop this key operation.
4. Keep pressing this key for two seconds to return to automatic range.
Deviation Display
∆
/%
Key
This key is the deviation display function. The deviation is displayed by
setting the reference luminous intensity and calculating the deviation to the
set reference value. The display is twofold:
(1) Deviation value display
∆
∆
= (measured value) - (reference value)
(2) Percent display
% = (
∆
/reference value) x 100
