® Junior II is a semi-automated reflectance photometer for in-vitro semi-quantitative reading of urine test strips from Boehringer Mannheim. The light sources (light-emitting diodes, LED’s for short) and reading times are optimized for the reaction chemistry and colour development occurring on the test pads.
Page 16
The photometric reflectance measurement for all of the parameters is carried out after an incubation time of 60 seconds. As with earlier urine analyzers from Boehringer Mannheim, allowance for intrinsic urinary colour, which is a recognized interfering factor, is made through measurement of a blank reagent pad, the so-called "compensation pad".
Miditron Junior II to compute and output the test results ® were derived from rigorous comparative tests carried out by Boehringer Mannheim with native urine. If required, the factory-set default ranges for Miditron Junior II may be ® changed to suit individual laboratories’ requirements.

12. Interface 12.8 Procedures for checking test bytes 12.8.1 European language variations of Miditron ® software: LRC test bytes The LRC test bytes are a Longitudinal Redundancy Check - a kind of longitudinal parity test of the bits contained in the data protocol. The procedure is quite simple: Byte for byte, the protocol is linked bit by bit to XOR.
12. Interface 12.8.2 American/Canadian language version of ® Miditron Junior II software: Check total The check total is reached simply by adding together the bytes to be transferred, the individual bytes being interpreted as positive, whole numbers. STX, BTX and CR are not included in the addition. The result of the addition is taken as modulo 256.
12. Interface 12.8.3 Automatic adaption to the test procedure used by the host ® Miditron Junior II is in a position to adapt itself automatically to the test procedure used by the host. If an error is discovered when checking the test bytes of the receive protocol, the check will be continued using the algorithms of the alternative procedure.
13. Troubleshooting The instrument contains software control functions which test the electronic hardware and peripherals after being switched on or after stand-by and which detect occuring errors during measurement. According to the importance of the error the just measured results are dismissed or in case of non-repairable errors (Major Error) the instrument changes to error condition.
13. Troubleshooting The SQW exit is activated at the RTC-component and therefore the command list of the RTC is checked. In addition, the condition of the RTC battery is checked via the VRT-flag. When starting the display test, first of all an initialisation command is sent to the display.
13. Troubleshooting Calibration errors are deviations exceeding 10 % of the known remission values of the profile grey strips respectively exceeding 1 % of the previous calibration values. In case of an error, the user is asked to repeat the calibration.

16. Interface Assignment Junior II has three RS 232 C serial ports for Miditron ® connecting the following devices: - host/PC - barcode reader - external printer These ports can be enabled and disabled in the interface setup menus. If "Host/PC Yes" is selected in the Setup menu, data will be sent to the host/PC port as an ASCII dataset.
17. Routine Care and Cleaning 17.1 General Miditron Junior II is a maintenance-free instrument. For ® reasons of hygiene, keep the exterior of the analyzer clean. Where necessary, the exterior surfaces may be cleaned with commercial cleaning and disinfecting agents, preferably 70 % isopropanol.
