Chapter 6 Maintenance
6.2.12 Cleaning Probe Wipe Block
After being used for a long time, the bottom of the probe wipe block may be
contaminated by blood and the inside of the block may also be contaminated by
the dirt sucked in. So you need to clean the wipe block regularly.
Follow the steps given below to do so:
At the Maintenance screen, press the appropriate arrow keys
([↑][↓][←][→])to move the cursor to Clean wipe block.
Present the probe cleanser to the sample probe and press [ENTER] to aspirate
the cleanser. Remove the cleanser after the probe has risen up.
Unscrew and remove the retaining screws with hands or screwdrivers (pointed
by the arrows shown in Figure 6-9) on the right plate of this analyzer.
Follow the arrow shown in Figure 6-10 to push and remove the right plate.
Follow the instructions displayed on the screen to place an empty cup below the
sample probe.
Press [ENTER] to soak the wipe block with the aspirated cleanser. The soaking
progress will be displayed on the screen, as Figure 6-14.

When the soaking is done, wipe the bottom of the wipe block with a probe
cleanser-dipped cloth that does not leave debris.
Press [ENTER] to flush the block and the inner surface of the probe.
After the flushing is done, the screen returns to the initial state.
When the accumulated analyzed samples reach 4,000, a dialog box will pop up
to remind to clean the wipe block. You may move the cursor to Yes and press
[ENTER] to start the cleaning, or to No and press [ENTER] to ignore the
message.
