4. Data processing

4.1. Data storage

The measurements made with the equipment can be assigned to a customer. For each customer a file with file name is created on the memory card (e.g.: DP3_0001.DAT). Into this file all measurements belonging to the customer are written. The files can be transferred to the PC using a card reader. With the software "DP3Report" a protocol for each check can be made. The following conditions must be fulfilled for using a multi media card:

- min. card volume 32 MB - max.32 GB (UHC)

- card formatted on 16 bit FAT or FAT32

- SD cards from SanDisk recommended

- PC with card reader

4.2. Edit customer

If the instrument gets switched on and a SD or MM Card with no customer data is inserted the inquiry follows whether you would like to edit a customer. If the measurement is to be assigned to a customer, press the key <F1> (<F4> = no: Measurement is made without allocation). Proceed as follows:

-select line to be filled out with the cursor keys <up/down> and confirm with <Enter>

-select keyboard <F3> (4 keyboard are available)

-select a character with the cursor keys <up/down/right/left> (selected character is black deposited)

-take over the character with <Enter> (the last character can be deleted with <F2>)

-repeat the procedure, until the desired designation is complete

-if a character is to be corrected, proceeded as follows:

-interrupt the character selection with <F4>

No customer

NO

Never pull out cards during data record - data loss and damaging

of the data carrier possible!

Page 10 ecom-DP3

-select the character to be corrected with the cursor keys <right/left>

-activate the character selection with <F4> and correct the character

-return to line selection with <F1> and choose the next line

If all necessary lines are filled out, a file is created with <F1>. With <ESC> you can leave to select a control program.

4.3. Select customer

With the help of the software „DP3Report“ customer data can be stored for the use at the DP3 on SD or MM Card. If the instrument gets switched on and a SD or MM Card with customer data is inserted a customer for allocation can be selected with "Search

for/Scroll" / <Enter>:

Scroll: Select „Scroll“, if you want to find the customer with the help of the cursor keys <up/down>. Further functions are:

<F1> = to the first customer <F2> = 10 customers forward <F3> = 10 customers backward

Search for:

Select „Search for“, if you want to find the customer by the input of at least 3 connected characters. Edit 3 characters as described in the chapter before and start the search with <Enter>. All agreements with the character sequence are picked out. The selection can be paged through with <F3> (with <F1> to the beginning of the selection).

If the desired customer is found, select with <Enter>. With „View/Modify“ the customer data can be viewed and modified.

Format: This function is usually needed by initial adjustment of the instrument at our factory (preparation of SD or MM Card for data recording).

Caution: All stored values will be cancelled! Please switch instrument after formatting off and on again!
