8-2 Shutdown
8.1 Shutting Down the Analyzer
The HM5 is designed to be left on at all times, except when it will not be used for long periods. During
such periods, shutdown functions are used to properly maintain the analyzer
If the analyzer will be unused or powered off for more than a week, use the Temporary
Shutdown
option: see below.
If the analyzer will be unused or turned off for more than two weeks, or will be shipped,
use the Prepare for Shipment option: see “Longer Term Shutdown or Storage” on
page 8-3.
8.1.1 Temporary Shutdown
If the analyzer will not be used for 7-14 days, shut it down as follows:
1. On the Home screen, select Exit > Shutdown.
2. Select
OK
to confirm.
3. When the analyzer displays a message and sounds a tone, power
it off using the power switch on the rear panel. The off position is
marked by the
O
symbol.
CAUTION: Always follow the instructions in this section when turning off the
analyzer.
The analyzer uses an isotonic saline solution in its fluidic system.
When the analyzer is shut down properly, as described below, it
rinses its fluidic system to remove this solution. Simply turning off
power does not allow it to perform this rinse, which can lead to salt
build-up in the system.
CAUTION: If an emergency occurs, turn off the analyzer using the power
switch on the back of the instrument, and unplug the power cord
from its outlet.
