1） Date and time： Please setting according to standard time, illegal date or time is invalidation. 2） Printer ： This instrument equipped internal heat sensor specially, which is shown as Figure 8-1. 3） Sound switching： Setting about turn on or off the buzz. Sound switching on, every warning will be sounded, or not. 4） Touch panel calibration ： Touch panel and pen is the entering way for URIT-660., touch screen takes resistance circuit, in some changeable external environment(temperature), touch screen may have slight excursion(click position is coincide with arrow), which may cause result error. At this time user should mark touch screen again. Press “Touch screen calibration” to enter windows. 3.7 Power off a) Press “Power off” in the main menu, select “OK”, screen will display “Thank you for using, Please turn off!” At this time, turn off the power switch on the rear panel of instrument. b) If you don’t want to turn off the instrument, select “cancel “, instrument will return to the main menu.

4. Maintenance 4.1 Daily maintenance 4.1.1 Routine maintenance 1） To keep instrument’s constant stability and accuracy, user should avoid any parts that may affect optics system. Wrong adjust of will affect test result. 2） Keep the cleanness of optics system to ensure normal function and exact result. Avoid any liquid flow into inside at the same time dustproof. Do not touch lens’ surface, filter and optical electric tester by finger. 9

URIT Medical Electronic Group Co., Ltd. 4.1.2 Routine cleaning 1） Turn the instrument off, pull out power plug. 2） Use one-time use glove and duster cloth which dipping water or soft eradicator to clean instrument’s surface, rail and flat rack. Caution: Organic solvent with strong corrosive acid, alkali and volatility such as acetone, ethoxyethane, chloroform to clean instrument’s surface is forbidden. User can only use neutral scour to clean.

4.2 Annually maintenance Annually maintenance is necessary to keep good working condition and prolong using life. Because of high maintenance requirements, this work should be done by engineer licensed by Urit, please contact with service department before maintenance.

4.3 Maintenance for a prolonged period of non-use or for transportation Due to various reasons, if instrument are not used or need to transport over 3 months, users should operate according to the following process: a) Storing and keeping the rest reagent according to relative specification. User should establish effective storing measure to avoid deteriorate, misusage, eat. Storing environment of reagent should avoid temperature extreme. b) Draw out the power cable, clean it and pack it with plastic bag. c) Packing the instrument with plastic bag and put it into packing box

Troubleshooting 5．Troubleshooting 5.1 Display shows nothing ① First check the lamp whether work or not. If the lamp work, it won’t be the problems of power, fuse and power cord. If not, check the power, fuse and power cord. ②If above all are normal, that should be the problems of inner connection. Open the cover and check the voltage of power output in the power board, especially the power output of the main board and display. If they are abnormal, fix or change the power board. If power outputs are normal, may be the problem of the display. 5.2 Incorrect results or no results ①Check the lamp to see if it’s still working. If the lamp works, check the voltage of data acquisition board. Adjust the board if the voltage is not right. After adjusting the board, change the data acquisition board when it still has problem. ②Lamp doesn’t work. User should check the filament whether it break or not. If the lamp is good, check the power, change the power board if necessary. ③Change the lamp if it is bad.

URIT Medical Electronic Group Co., Ltd. 5.3 Display normal, but keyboard no reaction ①Change the keyboard and try again, if it’s normal that should be the problem of the keyboard. ②It’s no reaction after changing the keypad. Maybe it’s the problem of the keyboard display interface or main board. 5.4 There is a lot of noise when run a test ①Maybe it’s the problem of the send sampler drive motor. Open the cover; watch the movement of the send sampler. If the send sampler goes straight without pause after pressing “run”, that may be the problem of the interface of main board motor or detection board. Send sampler hitting baffle spacing makes the noise. ② Maybe it’s the problem of the light source motor. If the source components are loose, install them again. 5.5 Printer doesn doesn’’t work ①Check the setting whether select the external printer. ②The printer is bad. ③The main board is bad. ④The cord is bad.

6. System Instruction 6.1 Electric circuit a) Switching mode power supply (SMPS)

Figure 6-1 SMPS

To judge a switching mode power supply whether good or not, the best way is that disconnect the SMPS and main board, input 220VAC only, use the multimeter to test whether have the outputs of +5VDC, +12VDC and +24VDC.
