Page 3: General Introduction
This meter is user-friendly, for field, industrial and laboratory applications. INITIAL INSPECTION Carefully unpack the unit and accessories. Inspect for damages made in shipment. If any damage is found, notify your Jenco representative immediately. All packing materials should be saved until satisfactory operation is confirmed. WATER PROOF Though the pH6810 meter is housed in a watertight case, DO NOT use it underwater. -

2. Wait for the unit and probe to dry completely before resuming operation. 3. If the unit does not function correctly after steps1 and 2, call JENCO for possible repair or replacement (see Warranty). INSTALLING THE BATTERIES The pH6810 meter is packaged with 4 “AAA” alkaline batteries required for operation. -

Page 7: Operational Procedures
OPERATIONAL PROCEDURES A. Buffer Set Selection The pH6810 meter has two buffer sets: 7.00, 4.01, 10.01pH and 6.86, 4.00, 9.18pH. The meter is factory pre-set at 7.00, 4.01 and 10.01pH. To change the buffer set, turn off the unit, then press and hold the “Stand”... -

Rinse the pH and ATC/Temp probe in distilled water and immerse them in the third buffer solution (either 9.18/10.01 or 4.00/4.01). Allow temperature reading to stabilize, then press “Slope” key to calibrate. The “WAIT” icon will flash until the unit detects a stable reading. Once the unit calibrates the third point and the unit will automatically exit the calibration mode. -

C. pH Measurements To take pH measurements, “STAND” and “SLOPE” icon must be on, indicating the unit is either dual-point or three-point calibrated and ready for measurements. If “STAND” and “SLOPE” flash, perform a pH calibration before taking measurements. Measurement with an ATC/Temp probe in the pH- AUTOLOCK mode. -

Press the “Mea.” key. The “WAIT” icon will start flashing. The unit is waiting for a stable reading. The display will track the pH value as sensed by the pH electrode probe. When the “WAIT” icon disappears, the reading is then “HOLD” and will not respond to further changes from sample. -
Page 13: Temperature Measurements
D. Temperature Measure The pH6810 can measure temperature independently with the ATC/temp probe without using the pH electrode. Place the ATC/temp probe in the sample. The unit will display the measured temperature. E. mV Measurements Measurement in the mV-AUTOLOCK mode. 1. -
Page 14: Ph Buffers
pH BUFFERS The temperature coefficient of pH calibration buffers 4.01, 6.86, 7.00,9.18 and 10.01 are stored inside the instrument. The buffers used to calibrate the instrument must exhibit the same temperature characteristics as the stored values. Temperature coefficient of the pH buffers 4.00 6.86 9.18... -
