Your MASTERSIX                       is                   supplied                             with a 9 V                  ETalkaline        battery. A                        rechargeable                   suitable
9 V battery may be used. The minimum
life duration of such a battery is sufficient
for about 2000 measurements.When the
warning symbol " EEll" comes on in the
display  another  50  measurements
(approx.)may be made.
Changingthe battery is easy: Slide off the

In the "FOTOMETRIE"mode (photomet-

Density measurements(function D) can
be made both in the reflectedand incident
light modes.
For measuring the colour temperature and
determining filters (function "COLOR") the
PROFI-color attachment must be coupled
to the meter. Readings obtained without
the COLOR attachment are not valid. (For
more  information  see  part  2  of  the
"Attachme nts"  i n strLtctions).

and take another reading. The factor is
automaticallyprogrammed into the meter
