Short operating instructions

Directions in Brief

Please read carefully the sections marked with this symbol in the margin!

Miditron®

Junior

II is designed for ease of use.To carry out routine strip measurements in Normal Mode

(sequential reading with automatic consecutive numbering), proceed as follows:

Switch on Miditron®

Junior

II.You see displayed:

Please empty the waste tray.

Once the waste tray is empty and the self-check has finished, the analyzer is

ready.You see displayed.

1. Press <Start> and follow the display messages:

2. When the status LED flashes green and the beep tone sounds ("Dip Strip 1" is displayed), briefly dip

the test strip in the urine sample (for about 1 second) and then remove it again, drawing the edge of

the strip over the rim of the specimen container to wipe off excess urine.

3. While the status LED is green, you may insert the test strip, reagent zones upwards, into the insertion

area between the two guides on the leading edge of the strip receiving tray.

The end of the test strip must be supported by the rear inside edge of the strip receiving tray

(Fig.10).

WARNING:To prevent injury, keep hands away from the analyzer when it is transporting

test strips!

4. After about 20 seconds the first test strip will be transported from the waiting position to the

measuring position and "PleaseWait" will be displayed.When the display shows "Dip Strip 2", repeat

the procedure for the second and any subsequent test strips.

5. The first test strip will be measured 60 seconds after it was dipped and the result will be automatically

printed as long as the internal printer was not disabled in the SETUP menu.When a strip is no longer

detected at the measuring position, Miditron®

Junior

II automatically returns to the initial state

("READY - <START>" is displayed).

IMPORTANT:

Before operating Miditron®

Junior

II for the first time, you have the option of entering various

settings in the SETUP menu.
