2 The Functioning of the Digipro F
2.1 Preparations Battery
The Digipro F operates with a 1,5 V AA-type battery (alkaline-manganese battery). Since the meter’s power
consumption is minimal, the battery will last for a long time. When the battery’s capacity becomes exhausted, the BAT
symbol appears on the display as a warning that the battery has to be replaced at the earliest possible opportunity.
Measurements cease to be possible if the display only indicates BAT. The battery must be immediately replaced.
To change the battery open the battery compartment of the Digipro F. Remove the exhausted battery and insert the
new one. Ensure correct polarity „+“ and „–“! Push back the bat tery compartment cover. Battery changing deletes all
stored values.
Self-Checking routine
The microcomputer performs a self-checking routine as soon as the battery
has been inserted. Every possible display segment appears in the display during
this routine. The duration of the self-checking routine is approx. 10 seconds,
but it can be interrupted by pressing any button. The factory programmed
basic settings are automatically displayed as soon as the
self-checking routine has been completed.
Basic values
ISO: 100/21 ° f: 5.6 COR: 0/ 1.0 EV: 12 t: 1/125 Flash: f 5.6 1/60
2.2 Incident and reflected light measurement
The features and measuring capabilities provided by the Digipro F are ideally
suited for the dedicated amateur and the professional photographer.
The swivel head will rotate through 180 degrees. This feature allows the
photographer to read the values measured in the display, while the
measuring head is directed towards the subject or light source.
When you remove the diffuser dome, reflected light and contrast
measurements can easily be taken.
Measurement by the incident method is far more accurate and reliable to
establish the correct exposure setting than the calculating of a mean value obtained with the reflected light
measurement in your camera. In the latter case, the reading depends upon the range of contrasts of the subject.
However, there is not always a uniform distribution of bright and dark areas of equal importance within the subject.
Incident light measurement is also imperative with inaccessible subjects.
For this purpose it is necessary to select a point that has the same lighting level as the subject. And then a meter
reading is taken that lies parallel with the projected connecting line between the actual subject and the camera. This
very convenient method of light metering at a point with the same lighting level is highly recommended for outdoor
shots. The measurement is performed with a complete „180°“ turn in front of the camera so that the reading is taken
with the meter pointing towards the camera, i.e. opposite the actual picture shooting direction.
Incident light measurement, i.e. with diffuser, also gives a precise reading of the brightness range of the lighting. Both
kinds of lighting – flash and ambient light – are measured with great accuracy by the incident light method with
diffuser.
In addition to this, the Digipro F also offers the reflected light measuring method. In this mode the diffuser dome
must be taken off and the meter is pointed from the camera towards the subject. The meter now only measures with
angle of 25 degrees the light reflected by the subject. Consequently, the reading always depends upon the inherent
brightness of the subject!! This means that inherently brighter subjects are not precisely measured and therefore
rendered darker. If readings are to be taken exclusively by the reflected light measuring method, then it is
advantageous for the professional to use a grey card (18 % re flection) in this mode. The reflected light method is used
to measure the subject contrast which is displayed by the Digipro F on its analog scale (see Section 3.2.4 Contrast
measurement, page 4).
3 The individual functions
3.1 Setting the film speed
Select ISO with the function buttons
Set the required ISO value with the value buttons
(display left: DlN value, right: ISO value)
Once the film speed has been set, it is transferred to the memory
of the Digipro F and maintained when the meter is set to any operation
function. It remains visible on the top right-hand side in the digital display.
Any change of the film speed directly influences the stored paired aperture and shutter speed values. The selected
film speed is retained in the memory until it is changed in the described manner.

ambient light is additionally indicated on the aperture scale (in our example f/8).
3.2.2 Multiple flash
Occasionally the light output from a single flash may not be sufficient to
enable you to work at the aperture desired. In that case, simply
push the top value button until the desired f/number appears in the
display. The digital display of the time t disappears and the number of
flashes required is indicated (e.g.: F4 = 4 flashes).
The Digipro F will calculate up to a maximum of 10 flash sequences.

(accuracy: 1/10 stops), also as a rounded mark in the analog aperture scale
• Select alternative aperture/shutter speed combinations with the value buttons.
3.2.4 Contrast measurement
• Select t with the function buttons
• Keep the measuring button M pressed
while aiming the meter at various areas of the subject. The analog
aperture scale displays the f-stop series between the two extreme
values and with the actual measured value flashing. The first
measured f-stop is displayed in the left-hand side of the display. It remains displayed as a reference value
(e.g. of a grey card)).
After the measuring button is released, the entire measured contrast range is displayed on the analog aperture
scale, and the last measured value will cease to flash.

3.4 Setting and measuring correction values
(see Section 3.4.4 Important remarks concerning correction values, page 6)
3.4.1 Setting correction values
• Select COR with the function buttons (the last valid correction
value appears in the display)
• Enter or change the correction value with the value buttons
The extension factor is shown in the right-hand digital display,
and the correction value in stops in the left-hand section.
Enter in 1/10th stops (small figure) within a range of ±7.9 exposure values.
A figure preceded by „–“ indicates an exposure extending correction.
Example: –3.1 stops equal factor 8.6.
In the event of an exposure shortening correc tion, only the left-hand display appears as an exposure value difference
in stops.
3.4.2 Measuring correction values
Correction values can also be directly measured. An evenly illuminated
surface and constant light level are required. Measure in the reflected mode.
• Press measuring button M and get a reference reading:
displayed as rF--
• Weaken light by holding e.g. a grey filter in front of the measuring
aparture. Press meassuring button M
The light reducing factor will be diplayed automatically in stops
at the right, as extension factor at the left.
Pressing one of the function buttons will transfer the correction value
to the memory of the Digipro F. The COR value is now automatically
taken into account in all subsequent measuring functions. The frame
around COR is retained as a reminder that a correction value was
entered.
3.4.3 Cancelling correction values
• Select COR with the function buttons
• Press measuring button (display rF --)
Select any other function with one of the function buttons.
Correction value is cancelled, and the frame around COR
disappears.
3.4.4 Important remarks concerning correction values
The Digipro F is a precision meter calibrated with great accuracy to provide exact ex posure data. Should you still not
be satisfied with the results, then you should remember that there are independent variables that can influence the
success of your exposures.
For instance:
the „true“ speed of your film can deviate from that on the pack
the „true“ shutter speeds and f-stops of your camera can differ slightly form the rated values
Deviations can arise when the film is processed.
Also there must be added purely subjective factors and matters of personal preference in the assessment of the
finished photos. However, you can calibrate your Digipto F to characteristics of your camera, your brand of film, your
processing methods, and to your projector.
We recommend the following procedure:
Take the readings of a few normal subjects with the utmost care by the reflected and incident light measuring
methods, and take five shots of each subject on colour reversal film. The first picture should be exposed with the
exposure settings supplied by the Digipro F. The exposure settings for the remaining shots are then increased and
decreased, respectively, by half an f-stop and then a full
f-stop. Make a note of the shooting conditions. These must not change while the five shots are being taken. Now
select from the processed pictures the one you consider to be optimal and compare its settings with the meter
readings.
If you find that you prefer exposures taken with settings that differ from those supplied by the meter, then these
settings can be programmed, as a correction, into your Digipro F. With your correction, the Digipro F will give precise
readings to produce optimal exposure results.
