Did you know the Triac centrifuge should be subjected to a
16-hour burn-in period as part of its Manufacturing Final Speed Calibration
Procedure?
Clay Adams advises that these proce-dures be performed after the
replacement of any major components, such as the motor or main PC board.
“URINE” MODE
1) Remove the head cover and install the four empty Trunions in
the head.
2) Remove the four screws that hold the control panel to the
centrifuge base. The control panel may now be removed.
3) Push the
“Urine” mode button, set to five minutes and push the
“Start” switch.
4) When the speed stabilizes, check the speed
with a Tachometer (calibrated).
5) Using the adjusting POT R7 on the right
side of the access hole under the brake button, set the speed of the
“Urine” mode between 2190 RPM and 2480 RPM. (Clockwise adjustments
will increase the speed.)
CAUTION: Use only an insulated or
non-conductive screwdriver for making any adjustments.
“BLOOD” MODE
1) Push “Blood” mode button, set timer again for 5
minutes and push the “Start” switch.
2) When the speed
stabilizes, check the speed with a Tachometer (calibrated).
3) Set speed of
the “Blood” mode between 3330 RPM and 3780 RPM using POT R8 on the
left side of the access hole under the brake button. (Clockwise adjustments
will increase the speed.)
4) After the calibration of the “Urine”
and “Blood” mode speeds, proceed to the “burn-in”
procedure.
“BURN-IN” PROCEDURE
1) Set centrifuge for continuous operation in the
“Blood” mode by taping the timer start switch in the actuated
position. (Centrifuge must run 16 hours at the “Blood” mode speed.)
2) After the 16-hour burn-in, remove the tape from the timer actuator.
3) Repeat the calibration procedures for the “Urine” and
“Blood” mode speeds.
4) Re-install the front control panel,
Note: The above “Burn-In” procedure may be avoided if the
“Urine” and “Blood” mode speeds are closely moni-tored
during the first week of operation. |
