INTRODUCTION

Thank you for purchasing the EcoSense pH1000A, a precise laboratory

benchtop meter that measures pH, mV 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.

The mechanical keys are highly reliable with tactile and audio feedback.

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

temperature simultaneously along with user prompts and mode

indicators.

An AUTOLOCK feature for both pH and mV 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 and mV

values, resulting in precise, repeatable and error-free measurements.

The pH1000A can also be used in non-AUTOLOCK mode.

Other features include single, dual or three point calibration; electrode

offset recognition; electrode slope recognition; electrode efficiency

display; built-in buffer coefficients; automatic or manual temperature

compensation; and long battery life. This meter is user-friendly for

laboratory application.

The following sensors are available for use with the pH1000A:

• 1101 pH electrode (item # 601101).

• 1102 pH/ATC (Automatic Temperature Compensation) probe

(item # 601102). This is a pH electrode with a convenient built-

in temperature sensor.

• 1103 temperature sensor (item # 601103).

• 115-1: ORP electrode (item # 605376).

Note: The instrument features a BNC connector for pH and ORP

electrodes. Any pH or ORP electrode with a BNC connection can

be used, but the 1103 temperature sensor will need to be used for

the instrument to automatically compensate pH measurements for

temperature.

or contact Technical Support at 800-897-4151 (+1 937 767-7241) or

[email protected].

GETTING STARTED

INITIAL INSPECTION

Carefully unpack the instrument and accessories and inspect for

damage. If any parts are damaged or missing, contact YSI Customer

Service at 800-897-4151 (+1 937 767-7241) or the authorized YSI

distributor where the instrument was purchased.

PRECAUTIONS

THE ELECTRODE

pH and ORP electrodes should not be allowed to dry out. When not

in use, place a small amount of pH 4 buffer, potassium chloride (KCl)

solution, or clean water in the electrode cap and install the cap over

the sensor. Deionized (DI) water should never be used for storage, as

it can permanently damage the electrode. DI water can be used for

rinsing between measurements or calibration points.

INSTRUMENT POWER

The pH1000A can be powered by the power supply included with the

instrument or with 6 “AA” 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 YSI

representative immediately.

INSTALLING THE BATTERIES

To install (or replace) the batteries, follow the procedure outlined

below.

1. Remove the battery cover by unscrewing (counter-clockwise) the

cover screw with a Phillips-head screwdriver.

2. Replace the old batteries (if applicable). Insert the new batteries,

ensuring correct polarities as marked.

3. Install the battery cover, then hand tighten the cover screw with a

screwdriver.

Battery Disposal

Battery disposal requirements vary by country and region, and users are

expected to understand and follow the battery disposal requirements

for their specific locale.

KEY PAD

Key Description

Power key. Press and hold for 3 seconds to

power on the meter. Pressing this key will also

turn the instrument off.

Up and down arrow keys are used to

manually enter temperature values.

They have no effect on the unit

when operating in ATC mode.

Mode Mode selects display mode. Pressing

this key changes the display sequentially

to display pH-AUTO, mV-AUTO, pH and

mV. The calibration values will not be

affected by changing the display modes.

Press the Mode key to exit a pH calibration

early (i.e. complete a 1 or 2 point calibration).

Clear Clear key. Press to clear any

errors that are displayed.

Press and hold for 2 seconds to clear all

calibration values stored in the internal

memory. After 2 seconds the unit will

enter the pH-AUTO mode. “AUTO” and

“CAL” will be displayed and one of the

buffers in the pre-selected buffer set will

start to flash. This means that the unit

must be calibrated again before use.

Stand/Slope is used for pH calibration

of the unit. Pressing and holding

the Stand key while turning on the

power will change the buffer set.

Meas.

Effic.

Meas. / Effic. is used to bring the unit out of

the AUTO condition when operating in the

pH-AUTOLOCK or mV-AUTOLOCK mode.

Press and hold this key for 5 seconds for

the electrode efficiency to be displayed.

Stand Slope

MAIN DISPLAY

Number Description

WAIT: This will be displayed when the unit is still waiting

for a stable reading.

BAT: Low battery indicator.

pH: Unit and mode indicators.

mV: Unit and mode indicators.

ATC/MAN: ATC indicator will be displayed if a

temperature probe is connected, otherwise the MAN

indicator will be displayed.

CAL: This will be displayed when the unit enters the

calibration mode.

AUTO: AUTOLOCK mode indicator.

Buffer selection: This indicator will flash if the pH1000A

needs to be recalibrated. This indicator also identifies

the buffer set currently selected.

LOCK: This will indicate the reading is frozen during

AUTOLOCK mode.

EFF: This will be displayed if the user is viewing the

efficiency of the electrode. It is recommended to clean

and/or replace the electrode when the efficiency value

is less than 90%.

MAIN DISPLAY: pH, mV and probe efficiency values.

SECONDARY DISPLAY: Temperature display in oC.
