We recommend to keep the packaging of the instrument in case of the need for further shipment Features SPLITGRADE is an electronic instrument intended to control the exposures and the contrast range of variable contrast papers VC during enlarging By printing the picture in two steps using maximum filter setting for yellow and magenta print results are greatly improved The contrast range of variable contrast papers will be perfectly matched to the given contrast range of the negative The characteristics of various variable contrast papers from AGFA AMALOCO BERGGER FORTE FOMA ILFORD KENTMERE KODAK MOERSCH TETENAL and ORIENTAL are already stored in the SPLITGRADE controller unit or could be added to the basic calibration set The composition and evaluation of the picture takes place under white light The exposure time and the grade are calculated after a scan of the pro jected negative The scan is supported by acoustic and optical signals The darkest and the brightest spot detected determine the result The exposure time and paper grade are automatically adapted also if another paper type is selected after measurement At any time the usr might override the calculated values or just set the exposure time and paper grade without using the probe Without an automatic filter module or light source SPLITGRADE can be used as a high quality B amp W analyser and exposure meter The focus light will be automatically switched OF
