GENERAL INTRODUCTION

Thank you for selecting the 6011M/6011EU meter. The

6011M/6011EU is a precision tool that measure pH, ORP 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 and buffer solutions.

This unit has a waterproof IP67 case. The touch mode keys are

highly reliable with tactile and audio feedback. This meter can

operate with one 9 V battery, typical battery life is 800 hours.

Re-calibration is not required when power is turned on again.

The front of the meter has a large LCD that displays pH or ORP and

temperature simultaneously along with user prompts and mode

indicators. The unit prompts the user through calibration and

measurement procedures.

An AUTOLOCK feature for both pH and ORP measurements

enables the unit to automatically sense the end point and “ √ ” the

display to indicate the end point value of a measurement.

AUTOLOCK and user prompts help to eliminate most errors in

determining pH and mV values, resulting in precise, repeatable and

error-free measurements. The 6011M/6011EU can also be used in

non-AUTOLOCK mode.

The unit is also equipped with a non-volatile memory allowing the

user to store 50 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 6011M/6011EU is available with pH, ORP and ATC

(Automatic Temperature Compensation) probes. Other features

include electrode offset recognition, electrode slope recognition,

electrode efficiency display, built-in buffer coefficients, automatic or

manual temperature compensation, long battery life and 50/60Hz

AC noise rejection. 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.

INSTALLING THE BATTERIES

OPERATIONAL PROCEDURES

A. pH Buffer Set Selection

The 6011M/6011EU meter has two buffer sets: 7.00, 4.01,

10.01 pH and 6.86, 4.00, 9.18 pH. The meter is factory

pre-set at 7.00, 4.01 and 10.01 pH.

To change the buffer set, turn off the unit, then press and hold

the “Stand” key while turning on the unit again.

[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 6011M/6011EU up to 3 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.]

a. Calibration with an ATC/Temp probe in the pH-AUTOLOCK

mode.

1. Turn the unit on. Press “Clear/Enter” key for 5 seconds, all

LCD elements will lit up. The meter clears all calibration values

stored in the internal memory.

2. Connect the pH electrode to the BNC connector and the

ATC/Temp probe to the ATC/Temp connector of the unit:

“ATC” icon will lit up. “pH” icon and “AUTO” icon will lit up. The

“buffer” icon will flash.

3. Rinse the pH and ATC/Temp probes in distilled water and

immerse them in the first buffer solution (either 7.00 or 6.86

pH). Allow temperature reading to stabilize, then press and

hold “Stand” key for 2 seconds to calibrate. The “ ” icon will

flash until the unit detects a stable reading. Once the unit

calibrates the first point, the “4.00（4.01）” and “9.18（10.01）”

icon will flash. The unit is ready to be sloped at the second

buffer.

[Note: If the first buffer solution is 7.00 or 6.86 pH, at this

moment, press the “Mode” key. The unit will exit the

calibration mode. Single point calibration is complete.

If the first buffer solution is 4.00, 4.01, 9.18 , 10.01 pH, at this

moment, the unit will automatically exit the calibration mode.

Single point calibration is complete.]

4. 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). Allow temperature reading to stabilize,

then press “Slope” key to calibrate. The “ ” icon will flash

until the unit detects a stable reading. Once the unit

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” key, the unit will

exit the calibration mode. Dual point calibration is complete.]

5. Rinse the pH and ATC/Temp probe in distilled water and

immerse them in the third buffer solution (either 4.00/4.01 pH

or 9.18/10.01 pH corresponding to the flashing number on

display). Allow temperature reading to stabilize, then press

“Slope” key to calibrate. The “ ” 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.

Three point calibration is complete.

6. The unit calculates and compensates for the pH electrode

slope deviation corresponding to the values of the calibrated

buffers. After calibration, press and hold “Mea./Eff.” key for

about 5 seconds to display the new electrode efficiency and

offset.

b. Calibration with manual temperature compensation in the

pH-AUTOLOCK mode.

1. Turn the unit on. Press “Clear/Enter” key for 5 seconds, all

LCD elements will lit up. The meter clears all calibration values

stored in internal memory.

2. Connect the pH electrode to the BNC connector of the unit,

“MAN” icon will lit up. “pH” icon and “AUTO” icon will lit up. The

“buffer” icon will flash.

3. Rinse the pH probes in distilled water and immerse it in the

first buffer solution (either 7.00 or 6.86 pH). Adjust the

temperature reading to that of the first buffer using the “Up” or

“Down” keys (0.0 to 60.0 ℃) before pressing “Stand” key.

Then press and hold “Stand” key for 2 seconds to calibrate.

The “ ” icon will flash until the unit detects a stable reading.

Once the unit calibrates the first point, the “4.00（4.01）” and

“9.18（10.01）” icon will flash. The unit is ready to be sloped at

the second buffer.

[Note: If the first buffer solution is 7.00 or 6.86 pH, at this

moment, press the “Mode” key. The unit will exit the

calibration mode. Single point calibration is complete.

If the first buffer solution is 4.00, 4.01, 9.18 , 10.01 pH, at this

moment, the unit will automatically exit the calibration mode.

Single point calibration is complete.]

4. Repeat steps 4 to 5 of “Calibration with an ATC/Temp probe

in the pH-AUTOLOCK mode” for dual and three point

calibration.

5. The unit calculates and compensates for the pH electrode

slope deviation corresponding to the values of the two

calibration buffers. After calibration, press and hold

“Mea./Eff.” key for 5 seconds to display the new electrode

efficiency and offset.

c. Calibration with an ATC/Temp probe in the pH NON-

AUTOLOCK mode.

1. Turn the unit on. Press “Clear/Enter” key for 5 seconds, all

LCD elements will lit up. The meter clears all calibration values

stored in internal memory.

2. Connect the pH electrode to the BNC connector and the

ATC/Temp probe to the ATC/Temp connector of the unit:

“ATC” icon will lit up. “pH” icon is on. The “buffer” icon will

flash.

3. Rinse the pH and ATC/Temp probes in distilled water and

immerse them in the first buffer solution (either 7.00 or 6.86

pH). Allow temperature reading to stabilize, then press and

hold “Stand” key for 2 seconds to calibrate. Once the unit

calibrates the first point, the “4.00（4.01）” and “9.18（10.01）”

icon will flash. The unit is ready to be sloped at the second

buffer.

[Note: If the first buffer solution is 7.00 or 6.86 pH, at this

moment, press the “Mode” key. The unit will exit the

calibration mode. Single point calibration is complete. If the

first buffer solution is 4.00, 4.01, 9.18 , 10.01 pH, at this

moment, the unit will automatically exit the calibration mode.

Single point calibration is complete.]

4. Rinse the pH and ATC/Temp probe in distilled water and

immerse them in the second buffer solution (either 4.00/4.01
