Page 3: General Introduction
GENERAL INTRODUCTION Thank you for selecting the 6179M meter. The 6179M 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: Power Input
POWER INPUT The model 6179M can be powered by an UL/CE approved 100 to 240 VAC adaptor as well as 6 “AAA” alkaline batteries. Check the label on the AC adaptor supplied with the instrument to make sure that the AC line voltage is correct. If the wrong AC adaptor is supplied, notify your JENCO representative immediately. -

Page 8: Operational Procedures
OPERATIONAL PROCEDURES A. pH Buffer Set Selection The 6179M 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/Clear” key to enter the buffer set selection mode. Use “Up” or “Down” key to select the preferred buffer set. - Page 9 To continue with two or more point calibration, the first buffer solution has to be either 7.00 or 6.86 pH.] Rinse the pH and ATC/Temp probe in distilled water and immerse them in the second buffer solution (either 4.00 / 4.01 pH or 9.18 / 10.01 pH corresponding to the flashing number on display).
- Page 10 sloped at the second buffer if the first buffer solution is 6.86 or 7.00 pH. [Note: At this moment, press the “Mode” key, the unit will exit the calibration mode. Single point calibration is complete. To continue with two or more point calibration, the first buffer solution has to be either 7.00 or 6.86 pH.] Repeat steps “e”...

The unit immediately calibrates the second point, the selected two buffers lit up and the remaining buffer starts to flash. The unit is ready to be sloped at the third buffer. [Note: At this moment, press the “Mode”...

Page 13: Temperature Measurements
Repeat steps “c” and “d” of “Measurement with an ATC/Temp probe in the pH NON- AUTOLOCK mode” D. Temperature Measure The 6179M 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. -

The "WAIT" icon begins to flash. Rinse the ORP probe in distilled water and immerse it in the standard solution. -
Page 15: Ion Calibration
Allow sufficient time for the display to stabilize. The meter will display the mV (RmV) value of the sample. ION Calibration The 6179M 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 16 Press “Slope/Enter” key. The mV value of the standard solution will appear on the main display. The “Wait” icon will flash until the meter detects a stable value. When the “Wait” icon disappears and the ion calibration value on the secondary screen moves up to the next value, the first point calibration is complete and the meter is ready for the second point calibration.
