[. . . ] After leaving Calibration mode, controller switches back to process temperature (for setting calibration temperature and process temperature, see section 7. 2. 3). 14 6. 2 ORP ­ mV Calibration This mode allows one-point calibration. Note: If upper and lower display read "CAL PH", see section 7. 4 for procedures on how to switch from pH to ORP mV readings. Upper display shows current mV output of electrode without any offset adjustment. The controller calculates the correction factor and returns to Measurement mode. HOLD CAL SETUP HOLD CAL OrP 226 C mV 15 7 7. 1 ADVANCED SET UP MODE Electrode Offset (OFS) sub-function This option is available only in the pH mode. An allowance of ±120mV is allowed to correct for electrode deviations. This feature is useful for prolonged on-line applications. The controller will add or subtract the value from the measured pH and display the correct value. Should the offset value be too high, consider performing maintenance on the electrode followed by calibration. If the calibration is unsuccessful, please replace the electrode. SETUP 1) Take a sample from the system and note pH reading HOLD Ofs displayed on controller. 2) Measure pH of sample using a calibrated pH tester, hand-held meter, or bench meter. Record the correct pH SETUP value. HOLD -0. 05 7. 00 3) Enter Advanced set-up mode. 4) Press or keys to scroll until upper display shows OFS. 5) Press ENTER key. 6) Press or keys until pH value coincides with correct pH value noted in Step 2. As the or keys is pressed to adjust pH value, the `offset' value in upper display also changes. 7) Press ENTER key to enter offset value. 16 Note: Offset value is reset during full calibration. Note: The offset parameter is blanked out during ORP operation. 7. 2 7. 2. 1 Setting temperature (Set oC) sub-function Selecting automatic or manual temperature compensation 1) Enter Advanced Set-up mode by pressing ENTER key. The lower display shows "Atc"; upper display shows "on" or "oFF" depending on whether or not ATC is selected. 5) Proceed with additional Advanced Set-up SETUP SETUP HOLD SETUP HOLD SEt o C Atc on procedures (press ENTER again) or return to Measurement mode by pressing and keys (escape) simultaneously. HOLD oFF Atc 17 7. 2. 2 Temperature calibration (ATC mode only) 1) Select "ATC on" as described above in Section 7. 2. 1. The SETUP HOLD on Atc current measured temperature is shown in the lower display. 3) Compare current measured temperature on the controller display to a thermometer known to be accurate. 4) Press or keys to scroll the lower display to match the correct value. 6) Continue with additional Advanced Set-up procedures, or return to the Measurement mode by pressing and keys (escape) simultaneously. SETUP HOLD 0. 0 25. 0 ATCC o 18 7. 2. 3 Setting manual temperature compensation SETUP Note: This option is not available when the HOLD oFF Atc controller is set for ATC operation. For manual temperature compensation, two SETUP different temperatures: process and calibration, HOLD 25. 0 can be input independently. This allows P. C calibration at a temperature other than the process temperature. Example: o setting a calibration temperature of 25 C allows calibration SETUP HOLD 25. 0 C. C using standard buffer solutions at 25oC, even if the process temperature is different. 1) Select "ATC oFF" as described above in section 7. 2. 1 2) Press ENTER key.
