Description
PREPARATION
The probe is first zeroed and then placed on the film on a light table.
The density value is then displayed on the 3-digit display. Light density is not uniform across a viewer.
To get an accurate reading the density reading should be made at the same point on the viewer where the zero was set.
MEASUREMENT
Place densitometer probe on viewer.
Switch on instrument.
Set zero on reference to 0.00.
Place film on viewer emulsion side up.
Place probe on film where reading is required.
Reading shows density of film.
Turn off instrument after use.
MAINTENANCE
When Lo Batt is displayed, replace battery (Type PP3 9v Alkaline) after first turning instrument off.
Slide off battery cover plate and insert battery.
Replace battery cover plate.
The equipment is only intended for use with X-Ray film.
