Another Google find. I lost my manual and from what I have read. Many other have too.
So I am posting this copy.
1. INTRODUCTION
The ILFORD EM10 exposure monitor allows you to determine the exposure required for colour and black and white print making.
The monitor can be used when printing slides or negatives, and is particularly recommended for use with ILFORD CIBACHROME-A print material.
The exposure monitor also automatically compensates for the change in exposure for different density colour filters in the enlarger. It cannot, however, be used as a colour analyser.
The EM10 exposure monitor is easy to use. Once calibrated, exposure determination from one slide to another or from one colour or black and white negative to another is simply a matter
of measuring the light level of a particular area of the image, and then varying the enlarger lens aperature until the green LED on the exposure monitor is lit.
The light sensitive cell on the monitor is positioned so it is close to the enlarger base-board during use, and accurately measures the amount of light received by the paper.
2. CALIBRATION
Calibrate the EM10 monitor by using one of the two methods below.
2.1 If you have not previously made prints:
1. Select a slide or negative, typical of those you wish to print.
2. Set the calibration knob to the calibration number on the base of the monitor.
3. With the slide or negative and recommended filtration in the enlarger, adjust the enlarger height to obtain a 20x25cm (8X10 inch) image on the baseboard.
4. In total darkness, except for the light fro the enlarger, place the monitor on the enlarger baseboard. For slide printing, the sensitive cell should be in a highlight area which just holds detail.
For negative printing, choose the brightest area of the image on the baseboard still showing detail.
5. Switch on the monitor and adjust the enlarger lens aperture until the green LED is lit. The enlarger lens may be set between f-stops for this purpose.
6. Using a mask (eg the ILFORD multi-mask printing frame), make four 10x12.5cm (4x5 inch) test exposures on a 20x25cm sheet of paper.
Suggested exposure times for colour and black and white negatives are 2, 4, 8, and 16 seconds, for CIBACHROME-A 20, 30, 40, and 50 seconds.
7. Process the print in fresh chemicals, following the manufacturer's recommendations. If one of the exposure times has not produced a correct density print, repeat steps 6 and 7 using different exposure times until the correct density is obtained.
When calibrating the monitor, judge only the density of the print; ignore colour balance.
8. Note the correct exposure time and the calibration number. You have now established the correct exposure time and calibration number for this pack of paper.
2.2 If you have a slide or negative of known exposure for a particular enlargement:
1. Place this slide or negative and any filtration used in the enlarger. Adjust the degree of enlargement and lens aperture to match your exposure data.
2. In total darkness, except for the light from the enlarger, place the monitor on the enlarger baseboard. For slide printing, the sensitive cell should be in a highlight area which just holds detail.
For negative printing, choose the brightest area of the image on the baseboard still showing detail.
3. Switch on the monitor and adjust the calibration know until the green LED is lit.
4. Note the calibration know setting. You have now established the correct exposure time and calibration number for your darkroom conditions.
3. USE
1. Ensure the calibration knob is set ot the appropriate calibration number.
2. In total darkness, except for the light from the enlarger, place the monitor on the enlarger baseboard. For slide printing, the sensitive cell should be in a highlight area which just holds detail.
For negative printing, choose the brightest area of the image on the baseboard still showing detail.
3. Switch on the monitor and adjust the enlarger lens aperture until the green LED is lit. The enlarger lens may be set between f-stops for this purpose.
4. Expose the paper using the same exposure time that you used for the calibration slide or negative.
4. HELPFUL HINTS
1. To ensure accurate readings, switch off the safelight when using the EM10 exposure monitor. Take all readings in total darkness except for the light from the enlarger.
2. The left hand red LED lights when insufficient light is reaching the baseboard. To increase the light level, choose a smaller f-number, eg f5.6 instead of f8.
The right hand red LED lights when too much light is reaching the baseboard. To decrease the light level, choose a larger f-number. An increase from one f-number to a larger f-number doubles the exposure time.
If only the left hand red LED will light, even at the largest lens aperture, the low light level may be due to a low wattage enlarger bulb, a high degree of magnification, a slow speed enlarging lens, under exposed slides of over exposed negatives.
Recalibrate the exposure monitor using a smaller lens aperture and correspondingly longer exposure time.
3. When calibrating the monitor with 20x25cm enlargements, the lens should be stopped down at least one or two f-stops and the calibration knob should be in approximately the centre of its scale.
This ensures there is enough latitude to open or close the lens when making larger or smaller prints, without changing the exposure time.
4. Batches of colour materials vary in speed and colour balance but is gener ally unnecessary to vary your standard conditions when changing batches of CIBACHROME-A.
Normally, it is sufficient to change the filtration according to the CIBACHROME-A pack - the monitor automatically compensates for the changes in filter density.
5. ILFORD ILFOBROM and ILFOSPEED black and white papers have equal speed for all contrast grades except grade 5, which is half the speed of other grades.
If the exposure monitor has been calibrated with one of the other grades of ILFOBROM or ILFOSPEED paper, use double the exposure time with grade 5 paper.
5. BATTERY
To fit a new battery, undo the three screws and remove the base of the monitor. Clip the battery into place.
The EM10 exposure monitor uses a Duracell MN1604(6LF22) battery or a PP3 (6F22) type battery. A rechargeable nickel cadmium battery can be used.
To conserve the life of the battery, switch off the monitor after use. The battery needs to be changed only when the LEDs are dim. If the monitor will not be used for some time, remove the battery to prevent damage by leakage.
