[. . . ] Press ENTER key to confirm your selection NOTE: Accepting the zero point will reset the zero offset settings made in OFS menu. 8. The temperature compensated sensor current (in nA) for the second point will be displayed. Once the reading stabilizes, the flashing symbols disappear and "READY" comes on. Press or key to select the desired saturation ("SAT %") or concentration ("Con ppm" or "Con mg/l"). NOTES: · · If you entered the Calibration mode from the Setup mode, the transmitter will return to the setup menu. If there is a calibration error the transmitter displays "ERR". In this case, press and keys simultaneously (escape) to restart the calibration beginning from step 1. When calibrating with manual temperature compensation, the transmitter automatically changes from the preset process temperature to the calibration temperature. After leaving the Calibration mode, the transmitter switches back to the process temperature (for setting the calibration temperature and the process temperature, see section 6. 3). · 17 Instruction manual Alpha DO 2000 5. 3 View Probe Condition The probe condition is an indication of its current working condition with respect to its original condition. The probe condition is calculated and stored in the controller each time calibration is done. You can view probe condition without entering into calibration mode. 1 % MEAS 89. 5 CAL 24. 5 ATC 2 000 C. CD ENT CAL 3 CAL DO ENT CAL ENT 4 ENT CAL 5 ENT CAL 6 % 0. 0 95. 5 100. 0 ADJ 1.

For real zero calibration, use the calibration procedure as described in section 5. If no simulator is used, a 22 k NTC must be connected to pins 24 and 25 of the terminal connector on the backside of the unit (see section 3. 2). 1 2 5 6 ENT ppt SETUP HOLD OFS ENT ENT SETUP HOLD NO OFS 2 ENT SETUP HOLD SETUP HOLD 00 .
