GENERAL INTRODUCTION

Thank you for selecting the 6010N meter. The 6010N 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 IP65 case. The touch mode keys are

highly reliable with tactile and audio feedback. This meter can

operated with one 9V battery, typical battery life is 1000 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 “ HOLD ”

the display to indicate the end point value of a measurement.

AUTOLOCK and user prompts help eliminate most errors in

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

error-free measurements. The 6010N can also be used in

non-AUTOLOCK mode.

The model 6010N 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.

WATER PROOF

Though the 6010N meter is housed in a watertight case, DO NOT

use it underwater. The watertight case prevents permanent damage

to the unit if accidentally dropped into non-corrosive solutions.

Follow these steps immediately if the unit is immersed in any

solution:

1. Rinse unit carefully with distilled water. After rinsing and drying,

inspect and clean connectors to remove all contaminants that

may affect probe connections.

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 6010N meter is packaged with one 9V battery required for

operation. To insert the batteries into the meter, follow the

procedure outlined below.

Figure 1: Battery compartment

1. Use a screw driver to remove the two screws and battery cover

to expose the battery compartment. (Figure 1.)

2. Replace the 9V battery.

3. Replace the battery cover and make sure to secure the two

screws for the water-tight feature.

[Note: Press the “ON/OFF” key to turn the unit on. If the unit is

running then you can press the ”ON/OFF “ key to turn the unit

off. The unit will automatically turn off after 30 minutes of no key

activity.]

OPERATIONALPROCEDURES

A. Buffer Set Selection

The 6010N 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” 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 6010N uses 2-point calibration. The first point must be 6.86/7.00,

and the second point can either be 4.00/4.01 or 9.18

/ 10.01.

[Note: For accurate measurements, it is recommended that pH

calibration is preformed once a week and after replacing the

electrode. ]

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

mode.

1. Turn the unit on. Press “CLEAR” key for 5 seconds, all LCD

elements will lit up. The meter clears all calibration values

stored in the internalmemory.

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

“STAND” 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).

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 “SLOPE” icon will flash. The unit

is ready to be sloped at the second buffer.

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

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

or 9.18/10.01). 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 second point and the unit will automatically exit

the calibration mode. Dual point calibration is complete.

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.

[Note: It is recommended to use a new electrode when the

efficiency value is over than 75%.]
