Instrument Description
The DTP32HS densitometer is a “high speed” color measurement instrument that reports
densitometric and dot data. The instrument is designed to calibrate color output devices
including large format printers, proofers, and digitally connected color copiers. The
DTP32HS densitometer is a “drop-in” replacement for the X-Rite DTP32R instrument.
This manual covers the installation, basic operation and maintenance of the instrument.
Specific instructions for using the instrument with your third-party software program can be
found in the third-party software documentation.
As the DTP32HS is designed to be a drop-in replacement for the DTP32R Automatic Strip
Reading Densitometer, reflection versions, it will by default report itself as a DTP32R. Most
existing software packages will reference a DTP32R in their connection menu while newer
software may use DTP32HS. Select DTP32HS if it is available, otherwise select the DTP32R.

Instrument Location Requirements
To ensure reliable read switch activation, the instrument must sit on a reasonably flat, level,
and stable surface.
Strip Feeding Requirements
To ensure consistent strip readings, you must feed the strip into the instrument at a
continual pace (without pausing) and speed before it is taken in by the drive motor. More
specifically, a strip cannot be fed into the instrument too quickly (more than 7.2
inches/second or 183 mm/second), too slowly (less than 2.6 inches/second or 66
mm/second), or intermittently (pausing one or more times). If you are experiencing any
strip-feeding problems, observe how fast the motor is moving the strip (about 5.4
inches/second or 137 mm/second) and try to match the speed as closely as possible.
Before feeding a second strip or a second pass of a multi-pass strip into the instrument, you
must momentarily pause (approx. 3 seconds) to allow the instrument to process data from
the first measurement. The LED is not lit when the instrument is processing data.
Instrument LED Indicator
The LED indicates a variety of instrument operation conditions, such as calibration mode
and operation. Below is a complete list of conditions reported by the LED.
Operation Mode
• Solid Green—self-test passed and instrument is ready for use with defined strip.
• Slow Flashing Green—strip reading in progress (strip being read) or ready for next pass
(multi-pass strip definition).
• Fast Flashing Green—strip reading was attempted but the wrong strip was read, or strip
was skewed during reading.
• Slow Flashing Amber/Green—a configuration barcode was scanned and the instrument is
waiting for the 2
• Fast Flashing Amber/Green—there was an error in recognizing a barcode or the
configuration failed. Reread the entire barcode, starting with the first pass.
Calibration Mode
• Slow Flashing Green—instrument calibration in progress (strip being read).
• Solid Green after Flashing Green—instrument calibration was successful and instrument
is ready for use.
• Fast Flashing Green—instrument calibration failed.
Error/Reset Mode
NOTE: When the instrument is first turned on, the motor runs, and the LED illuminates red while
performing self-tests. Self-tests are completed in approximately 2 to 3 seconds, at which time the LED
turns green and the motor stops under normal conditions.
nd
or 3rd barcode pass.
• Fast Flashing Red—incorrect power supply attached. Verify correct 12-volt power supply
is used.
• Slow Flashing Red—a factory reset is in progress.
• Flashing Red/Green— the host firmware loader program is reprogramming the
instrument.

Calibration
Frequency of Calibration
Your DTP32HS should be calibrated weekly. Refer to the following procedure for details on
the calibration process.
Reflection Reference Handling
Handle the reflection reference by the edges. Make sure that the reflection reference is free
of dust, dirt and smudgemarks. Refer to General Maintenance Section for cleaning
procedure. Always store the reflection reference in it protective envelope away from light
and heat.
Calibration Procedure
A calibration can be performed at any time. All that is required is that you insert the
reflection reference into the instrument as you would with any other strip.
1. Center the designated end of the reflection reference under the alignment mark.
2. Insert the reference strip until it is automatically advanced by the drive motor. Refer to
“Strip Feeding Requirement” for more information.

3. The LED slowly flashes green while the strip is pulled through the instrument and out the
back. The LED turns solid green and a short beep sounds after a successful calibration. If
the calibration fails (fast flashing green LED and long beep), verify strip is clean and reread.
4. Place the reflection reference in its protective envelope and store away from light and
heat.

DTP32HS DENSITOMETER
Strip Measurement
Important Notes
• You should refer to the documentation for the software program that you are using with
your instrument. All applications that utilize this instrument must be running during
measurements.
• The strip must have at least a 1.2″ (30.5mm) leader before the leading edge of the first
step. Contact X-Rite Applications Support if additional information is required. Inspect
the strip for spots or defects on the steps. Defects may cause inaccurate measurements.
• The darkest patch of a strip must be read first unless there is at least 1.1″ (27.9mm)
unprinted trailer after the last patch.
• Some software packages define strips as “multi-pass” where all color passes must be
read before a conformation is displayed on the monitor. In these cases, a successful
reading of a color pass is shown by the instrument slowly flashing green after the
reading. This indicates that you may continue to the next color pass. Fast flashing of
green indicates a re-read is required on the pass. The instrument’s LED will stay at solid
green after all passes are successfully read.
Strip Positioning and Measurement Techniques
The following information is provided to familiarize you with reading strips, a series of
printed control patches.
1. Select strip type to measure from the host software.
2. Position the strip so that the group of patches to measure is directly under alignment
mark on the cover.
3. Insert the strip until it is automatically advanced by the drive motor. Refer to “Strip
Feeding Requirement” for more information.
For large strips (media that extends outside the left side of the cover), guide the strip
with slight pressure. This prevents skewing of the strip as it is measured. Do not “tug”
forwards or backwards on strip while the internal motor is pulling the strip through.
4. The LED slowly flashes green while the strip is pulled through the instrument and out the
back.
A successfully reading is verified by a solid green LED and a short beep on the
instrument, and a conformation message on the computer monitor.

DTP32HS DENSITOMETER
Technical Information
Instrument Reset
Note: When performing an Instrument Reset, which restores the X-Rite Factory Defaults, you will have to
ensure the correct configuration for your software is then restored.
The following procedure resets DTP32HS to the factory default settings.
1. Disconnect power from the instrument.
2. Insert a piece of paper or a strip into the instrument past the front idler rollers.
3. Reapply power to the instrument.
4. After the LED begins to flash red slowly, remove the paper The factory defaults are now
reinstated.
Drive Wheels Rotation Timer
The instruments rubber drive wheels may develop temporary flat spots if the instrument sits
idle for and extended period of time. These “flat spots” could cause the first few moments of
a reading to contain unwanted noise. To prevent this condition, the instrument incorporates
an automatic timer that rotates the drive wheels for 10 seconds after a 12 hour, non-use
period. A reading or computer command that occurs during a wheel rotation timer cycle will
override the cycle and the clock resets.
Technical Notes
Firmware Update
After updating the instrument firmware you must power down the instrument and then
power it back up. This ensures that the instrument functions properly and user-configurable
settings are restored to the factory defaults.
Calibration Strip
The number of steps in the strip definition must be set to a minimum of five to achieve a
successful calibration using the X-Rite calibration reference strip.
