Page 8: Operational Procedures
OPERATIONAL PROCEDURES lope A. pH Buffer Set Selection The 6177M/6177EU meter has two buffer sets: 1.68, 7.00, 4.01, 10.01, 12.46 pH and 1.68, 6.86, 4.00, 9.18, 12.46 pH. To change the buffer set, turn off the unit, then press and hold the “Stand”... - Page 9 Press “Mode” key to go to pH-AUTOLOCK mode. “ATC” icon, “pH” icon and “AUTO” icon will lit up. The "CAL" icon begins to flash. Rinse the pH and ATC/Temp probes in distilled water and immerse them in the first buffer solution. Allow temperature reading to stabilize, then press and hold “Stand”...
- Page 10 Connect the pH electrode to the BNC connector of the unit. Press “Mode” key to go to pH-AUTOLOCK mode. “MAN” icon, “pH” icon and “AUTO” icon will lit up. The "CAL" icon will begin to flash. Rinse the pH probes in distilled water and immerse it in the first buffer solution.
- Page 11 [Note: If the first buffer solution is 7.00 or 6.86 pH, at this moment, press the “Mode” key, the unit will exit the calibration mode. Single point calibration is complete. If the first buffer solution is 1.68, 4.00, 4.01, 9.18, 10.01 or 12.46 pH, at this moment, the unit will automatically exit the calibration mode.
