GENERAL INTRODUCTION
Thank you for selecting the 6179MB meter. The 6179MB 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. The 6179MB is a 5th
generation pH/ORP/ION/temperature Bluetooth benchtop meter
with iOS and Android tablet connectivity.
This meter has a waterproof IP54 case. The mechanical keys are
highly reliable with tactile and audio feedback. It is powered by six
AAA-size alkaline batteries or with a UL/CE approved AC adapter
(OUTPUT:DC 9 V). The meter also displays a “BAT” message when
the batteries are in need of replacement. Re-calibration is not
required when power is restored.
The front of the meter has a large LCD that displays pH , mV , Rmv,
ion and temperature measurements along with user prompts and
mode indicators. The unit prompts the user through calibration and
measurement procedures.
An AUTOLOCK feature for pH, mV (RmV) and ion measurements
enables the unit to automatically sense the end point and “LOCK”
the display to indicate the end point value of a measurement.
AUTOLOCK and user prompts help eliminate most errors in
determining pH, mV (Rmv), ion values, resulting in precise,
repeatable and error-free measurements. The 6179MB can also be
used in non-AUTOLOCK mode.
The unit is also equipped with a non-volatile memory allowing the
user to store 750 different sets of readings. This unit will assign a
site number for each set of reading so the user can review the data
easily.
The model 6179MB is available with pH, ORP, ion and ATC
(Automatic Temperature Compensation) probes. Other features
include up to 5 point calibration for pH , 2 to 5 point calibration for
ion, 1 point calibration for ORP, electrode offset recognition,
electrode slope recognition, electrode efficiency display, built-in
buffer coefficients, automatic or manual temperature compensation
and 50/60 Hz AC noise rejection. This meter is user-friendly for
laboratory application.
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

3
until satisfactory operation is confirmed.
POWER INPUT
The model 6179MB can be powered by an UL/CE approved 100 to
240 V AC 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.
INSTALLING THE BATTERIES
To insert the batteries into the meter, follow the procedure outlined
below.
1. 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)
2. Replace the old batteries with new ones and install them in the
correct polarity position.
3. Put the battery cover back on the instrument. Use a Philip
screw driver and turn the screw in the clockwise direction to
lock the battery cover.

OPERATIONAL PROCEDURES
A. pH Buffer Set Selection
The 6179MB 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. Press “Slope/Enter” key to save the
selected buffer set.
[Note: There is no need to repeat this procedure every time the
unit is power up unless one decides to change the buffer
settings.]
B. pH Calibration
The 6179MB uses up to 5 point calibration.
[Note: If the device is required to perform more than one
calibration points, the first calibration point must be 6.86/7.00
pH.]

begins to flash.
d. 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” key for 2 seconds to calibrate. The“WAIT”icon
will flash until the unit detects a stable reading. Once the
unit calibrates the first point, the selected buffer will lit up
while two other selectable buffers start to flash. The unit is
ready to be 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

J. Save, Recall and Delete Data
1. Saving readings to memory.
a. In the measure modes, press and hold “Slope/Enter” key
for 2 seconds to save data. The “ID” icon and number with
the corresponding site number will lit up for a brief moment
to indicate a successful data save. Saving is now complete.
b. If the “Full” is displayed, this means that all 750 data saving
sites are used up. No new data can be saved until existing
saved data are deleted.
2. Recalling readings from memory.
a. Press “Mode” key until the “dAtA rCL” will show. Press
"Slope/Enter" key to go into “Recall” mode.
b. To view data, press “Up” or “Down” key to select the
storage site number and displays the corresponding

18
record.
c. Press “Mode” key to exit “Recall” mode.
3. Deleting data.
a. Press “Mode” key until the “dEL onE” or “dEL ALL” will be
displayed. Then press the “Slope/Enter" key to go into the
corresponding “Delete one” or “Delete ALL” mode.
b. In the “Delete ALL” mode, press the “Slope/Enter” and
enters the selection screen. Using the “Up” or “Down”
key to select “YES” or “no” for clearing all stored data. To
clear all data, must select “YES” and press the
“Slope/Enter” key. “nonE” will be displayed after data is
completely deleted.
c. In the “Delete one” mode, press the “Slope/Enter” and
enters the selection screen. Using the “Up” or “Down”
key to select data to be deleted. Then press “Slope/Enter”
key to delete. Deletion is now complete. The next set of
saved data will automatically move up a slot in the storage
site.
d. Press “Mode” key to exit “Delete” mode.

K. 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 meter. The buffers used to calibrate the meter must exhibit
the same temperature characteristics as the stored values.
