[. . . ] Upper display shows current mV output of electrode without any offset adjustment. 4) Press or keys to adjust mV value to that of standard solution. 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. The SETUP annunciator appears at the top of display. Lower display shows on-line measured pH value. Upper display shows current offset value. 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. See section 6 for full calibration instructions. 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. 2) Press or keys to scroll until display shows "Set oC". The lower display shows "Atc"; upper display shows "on" or "oFF" depending on whether or not ATC is selected. 4) Press or keys to toggle between ATC on and off. 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. [. . . ] These electrodes have integral 5 meter measuring cable. Please ask your authorised distributor or dealer for the prices, extension cables, tee joints, electrode assembly and buffer solutions. 29 10 GENERAL INFORMATION 10. 1 Warranty Thermo Scientific warrants this product to be free from significant deviations in material and workmanship for a period of one year from the date of purchase.
