2.2 POWER SUPPLY
Use ONLY the power supply packaged with the HemataStat II. Verify that the
ON/OFF switch located on the top of the centrifuge is in the OFF "
" position.
Always plug the power supply into the rear of the device first
and then plug the threeprong end into an electrical outlet. Press the ON/OFF switch to the ON " ʘ" position.
The lid will automatically open and the LCD will display the main menu.
2.3 OPTIONAL RECHARGEABLE BATTERY PACK
A. INSTALLATION
For complete portability, the HemataStat II will operate on a rechargeable
battery pack, which can be ordered as an option. The battery pack will need to
be installed in the device as described below and fully charged before normal
operation.
1. Make certain the lid is closed and locked and the centrifuge is unplugged
from the electrical outlet. Lock the lid by firmly pressing down on the lid
tab.
2. Place the device upside down on a smooth, flat surface and on a cloth or
other protective material to prevent scratching the lid.
3. Locate the battery pack cover. Using a small head Phillips screwdriver,
remove the screws holding the battery pack cover in place. Retain the
screws. Remove the battery pack cover.
4. Connect the battery pack plug into the connector loc ate d in side th e ba tter y
pack cavity. Put the connector inside the hole of the housing with the
connector release tab facing up. Position the battery pack inside the
compartment. Lay the cable along side the batter y pa ck t o av oid cri mpin g.
5. Replace the battery pack cover and secure with the screws provided.
6. Plug in the HemataStat II and fully charge the battery pack.
B. CHARGING THE BAT TERY PACK
The battery pack is always charging whenev er the HemataStat II is plugged into
an electrical outlet. Since the battery pack cannot be overcharged, the device
may remain plugged in continuously without harm. Charge the battery pack
overnight (or an equivalent period of time). The percentage of remaining
battery pack capacity may be determined at any time by performing the
following procedure.

1. Unplug the device from the electrical outlet.
2. Press the ON/OFF switch to the ON position. The LCD should display the
main menu.

ENTER FUNCTION:
READ 1.1 (OR 0.5) SPIN
RUN
3. Press the RUN and ENT buttons simultaneous ly and hold them dow n un til
the battery pack capacity is displayed.
When there is 20% capacity remaining, the main menu LCD will flash as
an indication that the battery pack is beginning to run down. It will still be
possible to operate the device for a few spins but the operator should
recharge the battery pack soon. Once there is no longer sufficient
capacity to operate the instrument, it will fail to complete a cycle and the
message CHARGE BATTERY will be displayed.
4. If the device is plugged into an electrical outlet with the ON /OFF switch in
the ON position and the RUN and ENT buttons are pressed
simultaneously, the LCD will display either CHARGING when in the
process of charging or TRICKLE CHARGING if fully charged.
REGARDLESS OF WHAT THE LCD MAY DISPLAY AT ANY GIVEN
TIME DURING THE CHARGING CYCLE, IT IS IMPORTANT TO
ALWAYS ALLOW THE BATTERY PACK TO CHARGE OVERNIGHT OR
AN EQUIVALENT PERIOD OF TIME TO ENSURE A FULL CHARGE.
A FULLY CHARGED BATTERY PACK WILL GENERALLY PROVIDE 75
SPIN CYCLES IF THE CENTRIFUGE IS TURNED OFF BETWEEN
TESTS.

SETUP PROCEDURE
3.1 DISPLAY OPTIONS
This setup procedure will allow the operator to store several functions in the display
option memory until a change is required. These functions include the selection of:

the tube size being used. (The ID of capillary tubes may vary slightly - up to
0.1mm.)
• Display language - English, Spanish, French, German or Italian
• HCT value suffix - Choice of displaying % sign or only the value itself
• Decimal point - Choice of displaying hematocrit in whole numbers or with a
decimal point.
Performing this setup procedure eliminates the need to enter these settings into the
device each time a test is performed.
