dried. Check this filter after the first 90 days of operation, then schedule
routine cleaning as necessary.
(E) Reagent pump calibration
The default setting for the volume calibration reminder is once every 30
days; although you may decide to shorten or lengthen this period. To
change the frequency of the calibration reminder, press the stylus in the
days box, then enter the new number of days between calibrations. (Dual
systems have two pumps and both should be calibrated.)
1. GO TO THE MANUAL MODE
2. With the elevators down, place rows of pre-weighed cups into the
AutoBlock. You must have multiples of 6 starting from left to right.
3. Prep the injection arm with DI into the drain. Use 3ml DI.
4. Raise the elevators. Align the injection arm to the first row and inject
10ml of DI water. Repeat as necessary.
5. Re-Weigh all cups and average the results.
6. GO TO THE SERVICE MODE.
7. Select the maintenance tab, select calibrate fill pump. (Dual systems
have two pumps.)
8. In the box labeled “injected ml”, type 10. If you used an alternative
volume place that volume in the box.
9. In the box labeled “resulting ml”, type in your averaged volume.
10. Press apply. Your AutoBlock pump should now be calibrated.
Note: To insure accuracy go back to the manual mode and test
appropriate volumes for injections. Repeat calibration as necessary
until an acceptable range is achieved. Factory calibration is +/- 2% at
10ml.
