Page 9: Operational Procedures
OPERATIONAL PROCEDURES lope A. pH Buffer Set Selection The 6377MB/6377BEU 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/Cal”... -
Page 10: Ph Calibration
B. pH Calibration The 6377MB/6377BEU uses up to 5 point calibration. [Note: If the device requires to calibrate more than one calibration point, the first calibration point must be 6.86/7.00 pH.] 1. Calibration with an ATC/Temp probe in the pH-AUTOLOCK mode. - Page 11 f. The third point, the fourth point and the fifth point are the same as the second point calibration. When the unit completed the fifth point calibration, press the “Mode” key and exit the calibration mode. g. The unit calculates and compensates for the pH electrode slope deviation corresponding to the values of the calibrated buffers.
- Page 12 3. Calibration with an ATC/Temp probe in the pH NON- AUTOLOCK mode. a. Turn the unit on. In the pH mode, press “Clear” key for 5 seconds, all LCD elements will lit up. The meter clears all calibration values stored in internal memory. b.

After calibration, press and hold “Mea./Eff.” key for about 5 seconds to display the new electrode efficiency and offset value. C. pH Measurements To take pH measurements, 6377MB/6377BEU must be calibrated before first use. 1. Measurement with ATC/Temp probe pH-AUTOLOCK mode. - Page 14 The “ATC” icon will lit up. b. Press “Mode” key until “pH”, “AUTO”, “ATC”, “buffer”, “WAIT” icons lit up. c. Rinse the pH electrode and ATC/Temp probe with distilled water and immerse in the sample to be measured. Remove any air bubbles trapped around the probe by shaking or stirring the probe.
