GENERAL INFORMATION

COMP-U-DIFF (model 10-329) is a differential cell counter and morphology data entry

workstation that provides efficient, direct computer entry of differential counts, RBC

morphology, comment, specimen and technical identification. COMP-U-DIFF guides the

operator through the data entry procedures via a series of English-text prompts displayed

on a large bright backlit LCD. The model 10-329 outputs its information to a laboratory

computer and/or ticket printer. With it’s 127 location batch memory, COMP-U-DIFF

may be used in a stand-alone, or autonomous, operation should the Laboratory computer

be busy or inoperative.

FEATURES

LCD display

All channels are displayed simultaneously with large digits on

bright backlit LCD display

Specimen Memory

COMP-U-DIFF has sufficient memory to store information from

up to 127 specimens.

Search Function

High speed search facilitates quick access of information

Hemogram Recall

This b-directional feature enables the user to view associated

hemogram data on the COMP-U-DIFF screen. A query to the

lab computer results in data being downloaded from the

computer to the COMP-U-DIFF screen.

Comp/Printer Ports

Two separate ports allow for easy interfacing to both the lab

computer and standard ticket printer.

Status Screen

To view internal function settings.

Count Correction

Permits the operator to decrement counts.

Non-total channels

Provides for optional counting of NRBC or other abnormal cells

independent of the differential count.

Output Data Format

The data format is a serial string of characters provided for easy

programming.

PHYSICAL LAYOUT

FUNCTION KEYS

Six function keys are located directly above the keypad area as shown in the

diagram below. Three of these keys access multiple screens where each key

depression advances to the next screen.

The function keys operate in the following manner each time one is

depressed.

[MODE] STORE

RECALL

BATCH

[MORPH/COMMENT] RBC1

RBC2

RBC3

RBC4

CMMT.....etc.

[COUNT] COUNT

PERCENT COUNT ....etc.

[EXEC] In STORE Mode. Writes report to batch

memory.

In RECALL Mode. Rewrites updated report

to batch memory.

[CLEAR]. In STORE Mode. Clears local memory.

In RECALL Mode. Clears selected report

from batch memory.

In BATCH Mode. Clears ALL reports in

batch memory.

[SEND] In STORE Mode. Transmits current results

to laboratory computer.

In RECALL Mode. Sends selected results to

laboratory computer from batch memory .

In BATCH Mode. Sends ALL results stored

in batch memory to computer.

[CLEAR] + [MORPH] Status Screen (user selectable programs.)

* NOTE: [ ] DENOTES A KEY

DATA ENTRY KEYS

The data entry keys provide two different operations.

1) The twelve keys add counts to different cell channels in COUNT

mode; or,

2) Enable the entry of specific numeric values [0-9] for identification

numbers, quantifiers, etc.

The [INC] and [DEC] keys provide two functions:

1) Screen cursor controls; or,

2) Pointer to memory locations for accessing data stored within the

batch memory.

COMP-U-DIFF QUICK DEMO

Note: This demonstration is intended as a quick introduction of the COMPUDIFF.

STEP 1. Plug the power to the wall socket. The screen default will appear as shown below. Note

that the Unit is in the STORE mode.

STEP 2. Enter Specimen ID Number (up to ten digits).

STEP 3. At this step the user could optionally press the [SEND] key transmitting the specimen

number to the Lab. Computer requesting Hemogram data to be displayed on the screen.

[see discussion on Hemogram lookup]; or,

STEP4. Press [COUNT] function key. The screen will display the twelve counting channels and

the three digit total count as shown below:

STEP 5. Depress the counting key as required. Each key depression will add a count to the

appropriate channel and add a count to the total count (except to the upper right key if it

has been designated as a non-totalizing channel for counting NRBCs).

When the user has completed counting cells, he/she may then optionally save the

specimen count results by pressing [EXEC] key, send the results to the laboratory

computer by pressing the [SEND] key; or if there is morphology or comments to be

entered proceed to the next step.

STEP 6. Press [MORPH] Key. Note that the cursor will be located on the ACANthocytes field.

Enter a quantifier (one of the lower sic keys) for the selected Morphology. To enter

additional morphologies on the same page, press the [INC] or [DEC] keys to select the

desired morphology. Note that the morphologies are presented in alphabetical order. To

select other pages depress the [MORPH] key through the four pages.

OPERATION

TO APPLY POWER

1. Plug power adapter connector into the associated socket located on the rear panel

of the COMP-U-DIFF.

2. Insert the power adapter plug into the wall outlet.

3. The screen will display the specimen entry form.

TO ENTER SPECIMEN ID AND COLLECTION DATE

1. The screen displays the word STORE and a flashing cursor will be noted over the

first digit of the Specimen number.

2. Enter the ten (10) digit Specimen number using [0-9] keys. [Note that data entry

is right justified].

3. Use the [INC] key to move cursor to the Date field. Enter the eight digit Data

using the [0-9] keys and the ddmmyyyy format.

TO ENTER DIFFERENTIAL COUNTS

The 12-channel keyboard for entering differential counts is shown below. While the

default key assignment layout is indicated. Alternate assignments can be

programmed in the laboratory computer to accommodate key assignment matched to

the tech identification code.

TO ENTER DIFFERENTIAL COUNTS (CONTINUED)

1. Press the [COUNT] key until the word TOTAL is displayed on the screen.

2. Enter differential counts by depressing the appropriate key for each category (i.e.

SEGS, BANDS, MONOS, etc.).

3. Each time a count is entered, both the corresponding channel count and the total

count are increased by one and, an audible click will be heard (except for non-

totalizing channel where the count is deposited only in associated channel, but

not in the total count).

ADDITIONAL CELL CATEGORIES

To expand the COMP-U-DIFF Cell counting capabilities to accommodate more then

12 categories the user may redefine channels 9 and 10. The default for these

channels is:

Channel 9 Promyelocyte

Channel 10 Immature Cells

The comment codes 801-807 are reserved for assigning cell types to channel 9 and

codes 901-907 are reserved for channel 10 (see exhibit 3). To assign cells to these

channels follow the steps described below (see comment entry).

1. Press [MORPH] key repeatedly until the comment screen is reached.

2. Press [INC] and [DEC] keys to access the required comment field.

3. Enter a valid cell category change comment.

4. Press [EXEC] key to save the comment.

5. The selected cell category is automatically inserted at the correct print location

on the ticket.

TO CONVERT COUNTS TO PERCENTAGE OF TOTAL

1. Press the [COUNT] key until the -%- is displayed.

2. Each channel is now calculated and displayed as percent of total; i.e., a two digit

number.

3. If the NRBC is designated for the non-total channel, the non-totalized value will

be normalized to the number of NRBCs per 100 WBCs.

TO SUBTRACT COUNTS (DECREMENT)

1. Press the [COUNT] key twice and hold down on the second press.

2. Press the cell category keys that you desire to subtract while holding down the

[COUNT] key. The screen will display –[DECR]- while in this mode.

3. Release the [COUNT] key to continue counting.

LOCKOUT FEATURE

1. At 100, 200, 300, etc. total cells counted. The keypad locks out any additional

entries.

2. To resume counting press the [COUNT] key and continue data entry.

NON-TOTAL KEY (OPTIONAL FEATURE)

1. Press the upper right hand counting key. The channel count increases by one but

the TOTAL does not. The NRBCs per 100 white cells displayed on the -%-

screen.

Note: This capability is factory preset. But maybe disabled by setting the appropriate

jumper plug.

CELL CATEGORY COUNTS EXCEEDING 99

A count exceeding 99 on any cell category will be indicated by an arrow to the left of the

pointing at the channel, which has overflowed. Each channel can tally up to 999 counts

in memory. However, only the two least significant digits are displayed due to

restrictions on screen spaces.
