1 INTRODUCTION

Thank you for purchasing the Salt 6 Salinity meter. These economy

microprocessor-based handheld meters deliver up to ±0.5% full-scale accuracy.

It has a large custom LCD (Liquid Crystal Display) for clear and easy reading.

The Salt 6 meter measures the amount of Sodium Chloride (NaCl)

concentration either in Percentage (%) or Parts Per Thousand (ppt), and

Temperature (°C).

Your meter includes a conductivity electrode (cell constant K = 1.0) with built-in

temperature sensor (Order Code: EC-CONSEN91B/ 35606-55), a rubber boot,

4 alkaline “AAA” batteries, instruction manual and warranty card.

Please read this manual thoroughly before operating your meter.

To order other accessories and buffer standard solutions, please refer to the

Accessories Section for more information.

2.2 Keypad

The Salt 6 salinity meter has 6 keys on its splash-proof keypad; ON/OFF,

HOLD/ENTER CAL, MODE, ▲and ▼keys. Some buttons have several

functions depending on its mode of operation.

OFF

•Powers on and shuts off the meter. Takes you directly into

measurement mode when meter is switched on.

CAL

•Enters into calibration mode for % (or ppt) and Temperature.

•To abort calibration or setup mode without confirming any set

value.

HOLD

ENTER

HOLD: Freezes the measured reading. To activate, press HOLD

key while in measurement mode. To release, press HOLD

key again.

ENTER: Press to confirm values in calibration mode, and to confirm

selections in SETUP mode.

•In Calibration Mode: Press to scroll through calibration values.

•In Setup Mode: Press to scroll through the setup sub-group

programmes.

MODE

•Selects measurement mode for salinity and Temperature.

•When pressed together with ON/OFF key, it will take you into

the SETUP mode. This allows you to customize meter

preferences such as selecting electrode’s normalization

temperature, temperature coefficient factor, and resetting the

meter to factory default.

1) Normalization Temperature

2) Temperature Coefficient Factor

3) Selection of ppt or % measurement mode (ppt or PrSn

4) User reset

3 PREPARATION

3.1 Inserting & Removing Rubber Boot

1) To remove meter from rubber boot, push

out from the bottom edges of meter until it

is completely out of boot. Ensure that the

cables of Conductivity electrode or

temperature probe are not connected.

2) To insert meter into rubber boot, slide in

from the top of meter before pushing the

bottom edges of meter down to set it into

position. Lift up the stand at the back of

meter for bench top applications if

necessary.

3.2 Inserting the Batteries

The battery compartment is found at the

back of instrument as shown. To open the

battery compartment:

3) Push in the direction of arrow

and lift up the cover.

4) Note the polarity of battery

before inserting into position.

5) After replacement, place cover

back and press down until it

locks tight.

3.3 Battery Replacement

A “LO” annunciator in the LCD alerts you when battery power is running low.

Replace with the same type as recommended by the manufacturer.

"LO" Battery Condition

Caution: Power off the meter when changing battery.

3.4 Conductivity Electrode Information

The Salt 6 salinity hand-held meter is supplied with a

electrode with a BNC connector. This electrode (Order

Part Number: EC-CONSEN91B/ 35606-55) comes with

Stainless Steel rings, cell constant of K = 1.0, and a built-

in temperature sensor for Automatic Temperature

Compensation (ATC). Its specially designed Ultem-body

housing has good chemical resistant properties. It

provides fast temperature response and reduces air

entrapment, which makes it easy to obtain accurate,

stable readings.

The probe materials used which have good chemical

durability include:

1. Polyetherimide (Ultem) – protective probe guard

2. Polybutylterphalate (Valox) – sensor housing

3. Stainless Steel (SS 304) – 2 steel bands

Instruction Manual Salt 6

Proper use of probe is essential to ensure

that the optimum measurement is taken in

a short time.

The removable protective plastic probe

guard is meant for simple periodic

maintenance and it must be kept in tact

during measurement and calibration.

Always immerse the probe beyond upper

steel band.

NOTE:

1) DO NOT remove the protective probe guard during measurement

and calibration as it may affect your readings.

2) We recommend that you do not submerge the probe above the

protective guard. You can submerge the cable for brief periods of

time, but not continuously.

See Section 7 - Probe Care and Maintenance” for more information.
