Appendix A -
The DTP 34 Quick Cal Densitometer is a "drop in replacement" for the X-Rite DTP32R (R for reflective) strip
reading densitometer.
There are a few differences in operation of
the Quick Cal compared to the DTP32. The
DTP32 (see diagram at right) has a display,
keyboard, and strip guide, whereas the Quick
Cal product has a single key and the different
process of reading a strip. In order to use the
Quick Cal product where a software
application expects the DTP32 product,
please consider the following.
Operation
Below we list some of the ways that the use of the instruments will differ. The items in italic are phrases often
indicated in the host software for the DTP32R.
•
Use of the strip guide – Insert strip at X
The DTP32R has a strip guide mechanism that ranged numerically from 5 to 30. Some software packages indicate a
setting for this guide. These prompts can be ignored with the QuickCal as no guide is required.
•
Inserting as strip – Insert Cyan strip
When asked to insert a strip, a QuickCal user will then position the instrument at the start of the row to be read,
push the measure button and read. For more about reading a strip see the Measurement Notes and Tips section of
the Manual.
•
Using the keyboard – Push Key #X
The DTP32R has four keys to control the menus found on the LCD. The DTP34 does not require unique key
sequences, because it is software driven, therefore these prompts can be ignored.
•
Calibration of the instrument – Go to page 2 to Calibrate
The DTP34 can be calibrated without using menus, as is required for the DTP32 product. A quick calibration can
be initiated like any other reading, and a full calibration is initiated by holding the button until the lights turn amber.
Please see the calibration section in the manual for a full explanation.
•
Configuration of the instrument – Go to page 3 to Configure the Instrument
Most software will automatically configure and setup the DTP32R or the DTP34 for use. Often, this equates to
selecting from various communications settings so the software can take over control of the instrument once it is
connected. For the few packages that require a manual configuration the DTP34 allows manual configuration by
reading X-Rite Set-up Barcodes. X-Rite Set-up Barcode pages are supplied on the QuickCal CD-ROM for some
manual configurations. Check the third party support folder on the CD-ROM to see if there is a configuration page
that contains all the settings for your software package. More information about reading bar codes is found in
section 2 of the manual. Further information about Quick Cal and third party support can be referenced at the
X-Rite website under the help desk area at the following location:
