The SCA-400
eclipsed the SCA-300 as the top-of-the-line analyzer in the SCA series. In
place of the accessory memory modules that the SCA-300 used, the SCA-400
had 8 programmable memory banks built in. With the 3 silicon cells in the
probe, and the 4 channel display, all values were available to the
operator with just one reading. The SCA-400 also incorporated timer
circuitry so that the unit was capable of providing both manual and
automatic exposure control. For black and white printing, it was also
capable of determining the required grade of paper as well as the exposure
time.

Used Advice: This
unit uses the same probe as the SCA-300 which is somewhat fragile and
difficult to repair. The microprocessor based circuitry uses a lithium
battery for memory storage which will probably require replacement. |
