Attaching the Cord Strain Relief

A cord strain relief and strap is supplied to help prevent
inadvertent cord disconnection during instrument use.

1. Attach the strap to the strain relief by inserting one of the looped ends into the small hole, and
then through the other looped end to tighten.

2. Insert the looped end of the strain relief strap into one side of the post at the back of the
instrument, and then out the other side. Note: You may need to use a small pointed object to
pull the loop around the post.

3. Continue pulling the looped end of the strap until the thicker shrink wrapped connection in the
middle passes around the post.

4. Next, insert the looped end of the strap through the small hole in the strain relief, and then
pass it over the 3 rings of the strain relief back towards the small hole.

CALIBRATING

The software application prompts for an instrument calibration when required. The frequency at
which this occurs depends on the application. Refer below for procedure.

The calibration reference consists of a ceramic disk for white calibration measurements, and a
trap opening for black calibration measurements. The instrument shoe fits snuggly in both
positions.

Refer to Cleaning section in the Appendices for information on cleaning the optics area and
references.

NOTE: Make sure to use the calibration reference supplied with the instrument for calibrating.

Do not substitute this reference with a reference from another instrument. The serial number
on the reference should match the reference (plaque) serial number on the instrument.

Calibration Notes

• Dirt or dust in the aperture area will cause an inaccurate calibration reading. Refer to the
Appendices for optics cleaning procedure.

• The white ceramic plaque in the calibration reference is dramatically affected by
smudge marks, dust, and finger prints. Refer to Appendices for calibration reference

cleaning procedures.

• The black trap should be cleaned periodically to remove any dust or
contamination. Refer to Appendices for black trap cleaning procedures.

• Do not release the instrument while taking a calibration measurement. If the
instrument is released, calibration will be aborted.

Calibration Procedure

1. When a calibration is prompted for by the application, select the appropriate option to initiate
the calibration.

2. Remove the protective cap from the white ceramic plaque in the calibration reference.

3. Position the instrument’s target window over the white ceramic plaque.

10

Ci51/Ci52 S P ECTROPHOTOMETER

Black trap opening

4. Press the instrument firmly to the shoe. Hold steady until the measurement status indicators
change to amber and then green. The calibration indicator should change to red.

5. Release the instrument.

6. Reinstall the protective cap on the white ceramic plaque.

7. Position the instrument target window over the black trap opening in the calibration reference.

8. Press the instrument firmly to the shoe. Hold steady until the measurement indicators change

to amber and then green, and the calibration indicator changes to green. This is an indication
that the calibration procedure was successful.

9. Release the instrument.

10. Store the calibration reference in a dry, dust free area, away from direct exposure to light.

OR

TAKING MEASUREMENTS

You should refer to the documentation for the software program that you are using with your
instrument. All applications that use the instrument must be running during measurements.

Sample Criteria

The instrument can take measures from just about any clean, dry surface that is reasonably flat.
The instrument shoe should be able to rest flat and steady on the sample area. If the item to be
measured is smaller than the shoe, you may want to make a platform—at the same height as the
item—for the rest of the instrument’s shoe to sit on.

NOTE: Never measure wet paint. Wet paint will contaminate the instrument.

Measurement Techniques

1. Clear the sample surface of any dirt, dust, or moisture.

2. Position the target window over the sample to measure. If possible, place the entire

instrument on the sample.

3. Press the instrument firmly to the shoe; the measurement indicators change to amber. Hold
steady until the measurement indicators change to green followed by an audible beep. This is
an indication that the measurement was successful.

NOTE: Your application may also require you to press the Measure button during a
measurement.

pressed

4. Release the instrument.

The measurement indicators change to red and an error beep occurs if the measurement was
unsuccessful. Refer to the Troubleshooting section in the Appendices for more details.

Cleaning the Instrument

Your instrument requires very little maintenance to achieve years of reliable operation. However,
to protect your investment and maintain reading accuracy, a few simple-cleaning procedures
should be performed from time to time.

General Cleaning

The exterior of the instrument may be wiped clean with a cloth dampened in water or mild
cleaner.

NOTE: DO NOT use any solvents to the clean the instrument, this will cause damage to the
cover.

Cleaning the Optics

The optics should be cleaned once a week in a normal environment. If the instrument is used in a
dirty or dusty environment, more frequent cleaning may be required.

Carefully lift the instrument, open the shoe and blow short bursts of clean, dry air into the
measurement port. This should remove any accumulated debris from the optics.

IMPORTANT: If can air is used for cleaning, do not invert or tilt the can during use. This could
cause damage to the optics.

Cleaning the Calibration Reference

The calibration reference consists of a white ceramic plaque and a green ceramic plaque (if
equipped), and a black trap opening.

The calibration reference should be cleaned periodically.

Ceramic Plaque Cleaning Procedure

1. Remove the protective plastic cap from the ceramic plaque.

2. Important: Always grip the ceramic plaque from the edges, being careful not to touch the
white/green surface.
Press downward on the ceramic plaque and turn counterclockwise until it stops. Lift upward
and remove the ceramic plaque from the base.

3. Clean the plaque using a mild soap and warm water solution. Thoroughly rinse with warm
water and wipe dry with a lint-free cloth. Do not use solvents or cleaners of any kind.

4. After the ceramic plaque is completely dry, align the large tab on the side of the ceramic
plaque with the large notch in the base. Compress the spring downward with the ceramic
plaque until it stops. Holding the ceramic plaque down, rotate clockwise until it stops. Slowly
allow the plaque to rise. The arrow on the ceramic plaque and the arrow on the base should
be aligned when properly positioned.

5. Reinstall the protective cap over the ceramic plaque when not in use.

fingers and separating.

2. Clean with clean, dry air, or wipe clean with a lint-free cloth to remove any dust or
contamination.

3. After cleaning, align the trap opening in the top section over the cone in the bottom section of
the reference. Assemble the two sections.

Note: The tabs will not lock correctly if assembled in the opposite direction.
