Notes
1. “Split Grade Mode” refers to the practice of making two exposures on VC paper, through soft and hard filters. The Analyser Pro and ZoneMaster II are not designed to do this - instead they assume a single exposure through the relevant filter. However, both products can compute a burn-in exposure using a different grade to the main exposure.
2. Dry down compensation is not necessary for exposure meters as they are computing the final dry density of the print. The compensation feature can also be used to make adjustments when prints are to be toned.

The StopClock Vario has all the features of the StopClock Professional except that it cannot be physically connected to a ZoneMaster II.

Notes:
1. Both units operate in a split grade mode as standard rather than varying the lamp intensities as per the Ilford controller. The StopClock 500 therefore does not have the dedicated split grade mode from the StopClock Professional.
2. Dry down compensation is not necessary for exposure meters as they are computing the final dry density of the print.
3. The Analyser 500 uses Absolute Grades, i.e. grade 2 is the same ISO(R) contrast whatever paper is in use.
