EC/TDS/SALT Testr

Large Screen Waterproof Multi Range

Conductivity/TDS/Salt Tester

with Temperature Display

Introduction

Thank you for selecting microprocessor-based waterproof EC / TDS / SALT tester with

large dual line display. You have one of the following models:

• ECTestr11

• ECTestr11+

• TDSTestr11

• TDSTestr11+

• SALTTestr11

Non-plus models

Non-plus models (ECTestr11, TDSTestr11 & SALTTestr11) come with user-replaceable

two-pin type sensor and have many user friendly features such as Dual-range

measurement, the Hold function, Automatic Temperature Compensation (ATC) and

Self-Diagnostic Messaging capabilities.

Plus models

Plus models (ECTestr11+ & TDSTestr11+) come with the user-replaceable cup type

sensor and have additional features such as Multi-range measurement, up to 3-point

calibration and higher resolution measurement.

Before You Begin

Remove the electrode’s protective cap. Soak the electrode for a few minutes in

alcohol to remove any oil stains on the electrodes which will affect the accuracy of

the tester. Rinse thoroughly with de-ionized water and shake off dry.

Switching On

Press ON/OFF

ON/OFF

ON/OFF key to switch on the tester. The LCD shows the power-up sequence

as illustrated in Figure 2.

When the tester is on, if you do not press a key for 8.5

minutes, the tester automatically switches off to conserve batteries.

Range Selection

Depending on the selected model, you can set the tester to limit its reading to a

particular measuring range (PU, LO or HI) or full scale (AUTO). The default setting

is AUTO. When you select a range other than AUTO, the tester can be calibrated

only for that particular range. If you try to measure a sample which has a higher

conductivity/TDS value than that of the selected measuring range, the LCD shows

‘OR’ error message. Refer Specif

HOLD key repeatedly

until you see the required range (PU, LO or HI).

Note:

Note: If no key is pressed within 5 seconds, LCD shows power-up sequence and

tester goes to measurement mode.

3. The tester automatically confirms the last selection if no key is pressed for 5

seconds. Upper display momentarily shows ‘CO’. The LCD shows power-up

sequence and the tester goes to measurement mode.

Measurement

1. Press the ON/OFF

ON/OFF

ON/OFF key to switch on the tester. The ‘MEAS’ indicators appears

when the tester is in measurement mode.

2. Dip the electrode into the test solution making sure that it is fully immersed.

Stir to clear any trapped air bubbles from the electrode and let the reading

stabilize. For plus models, you can opt for the cup style measurement by filling

the electrode cup with sample of test solution.

Note:

Note: The LCD indicates ‘Or’ (over range) if the reading is outside the selected

range. If this occurs, select an appropriate range to suit the reading.

3. The upper display shows the main reading (conductivity/TDS/Salt) of the

solution, automatically temperature compensated (ATC) to normalized temperature

of 25°C. The lower display shows the temperature of the solution.

HOLD Function

This feature lets you freeze the display for a delayed observation.

1. Press HOLD

HOLD

HOLD key to freeze the measurement. The tester goes to hold mode and

‘HOLD’ indicator is displayed in LCD. The measurements are frozen and the ‘MEAS’

indicator disappears.

2. Press HOLD

HOLD

HOLD key again to release the measurement. The ‘HOLD’ indicator is no

longer displayed. The tester goes back to measurement mode.

Temperature Unit of Measurement Selection

This feature lets you set the unit of measurement of temperature to either Celsius (°C)

or Fahrenheit (°F).

When the tester is in the measurement mode, press °C/°F

°C/°F

°C/°F button. The temperature

display toggles between the Celsius and Fahrenheit reading.
