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

Press ON/OFF ON/OFF ON/OFF ON/OFF key to switch on the tester. The LCD shows the power-up sequence ON/OFF
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
• SALTTestr11
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 Specif Specif Specif Specifica ica ica ica ications

2. The tester goes to range selection mode. The LCD shows the currently selected
Range (the default is AUTO) in the lower display. The upper display shows the
maximum possible reading for the selected range. Press HOLD
until you see the required range (PU, LO or HI).

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 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:
Note: The LCD indicates 'Or' (over range) if the reading is outside the selected Note: Note:
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 HOLD
'HOLD' indicator is displayed in LCD. The measurements are frozen and the 'MEAS'
indicator disappears.
HOLD HOLD
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.
