Page 3: General Introduction
GENERAL INTRODUCTION Thank you for selecting the 6179 meter. The 6179 is a precision tool that measures pH, mV, ion concentration and temperature. A built-in microprocessor stores, calculates and compensates for all parameters related to pH determinations including pH electrode temperature characteristics, electrode slope deviations, offset and buffer solutions. -
Page 4: Installing The Batteries
INSTALLING THE BATTERIES To insert the batteries into the meter, follow the procedure outlined below. Use a Philip screw driver and unlock the battery cover by turning the screw driver in the counter clockwise direction. After unlocking the screw, take off the battery cover (Fig.1) Replace the old batteries with new ones and install them in the correct polarity position. -

Page 7: Operational Procedures
OPERATIONAL PROCEDURES A. pH Buffer Set Selection The 6179 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. In pH mode, press “Set” to enter the buffer set selection mode. - Page 8 for calibration. Rinse the pH and ATC/Temp probes in distilled water and immerse them in the first buffer solution (to perform 2 to 5 point calibration, the first calibration point must be 6.86/7.00). Allow temperature reading to stabilize. Press and hold “Stand”...
- Page 9 calibration point must be 6.86/7.00). Adjust the temperature reading to that of the first buffer using “Up” or “Down” (0.0 to 60.0 ℃). Then press and hold “Stand” for 2 seconds to calibrate. The “WAIT” icon will flash until the unit detects a stable reading.
- Page 10 temperature reading to stabilize. Press “Slope/Enter”. The unit immediately calibrates the second point, The selected two buffers lit up and the remaining buffer icons start to flash. Dual point calibration is now complete. Press “Mode” to exit. To continue with the third, the fourth and the fifth point calibration, repeat step 4.

C. pH Measurements To take pH measurements, 6179 must be calibrated before first use. Measurement with an ATC/Temp probe in the pH- AUTOLOCK mode. 1. Connect the pH electrode to the BNC connector and the ATC/Temp probe to the ATC/Temp connector of the meter. -
Page 12: Temperature Measurements
Repeat steps 2 to 4 of “Measurement with an ATC/Temp probe in the pH NON- AUTOLOCK mode” D. Temperature Measure The 6179 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. -
Page 13: Ion Calibration
Allow sufficient time for the display to stabilize. The instrument will display the mV (RmV) value of the sample. ION Calibration The 6179 can measure ion concentration when using an ion selective electrode (ISE) for the specific ion of interest. The available ion calibration values are 0.10, 1.0, 10.0, 100.0, and 1000. - Page 14 is now ready for a fresh calibration. Connect the ISE to the BNC connector of the meter. “MAN” and “AUTO” icons will lit up. The "CAL" icon will begin to flash. Rinse the ISE in distilled water and immerse it in the first standard solution.

Page 17: Ph Buffers
pH Buffers The temperature coefficient of pH calibration buffers 1.68, 4.00, 4.01, 6.86, 7.00, 9.18 , 10.01 and 12.46 pH are stored inside the instrument. The buffers used to calibrate the instrument must exhibit the same temperature characteristics as the stored values. -
