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. ]
