1. INTRODUCTION

1.1 Introducing the EcoScan Series

Thank you for purchasing Eut ech Instruments’ EcoSc an Conductivit y and Tot al Dissolved Solids (TDS) meter series. These economy microprocessor-based handheld meters deliver up to ±1% full-scale accuracy. It has a large custom LCD (Liquid Crystal Display) for clear and easy reading.

EcoScan CON 5 measures Conductivity (uS/mS) and Temperature ( the EcoScan TDS 5 measures Total Dissolved Solids (TDS) and Temperature

C). These sturdy meters measure up to 3 different ranges with auto-ranging

( capability that switches to appropriate measuring range automatically.

The instruction manual is organised for quick reference with step-by-step procedures that give you thorough review of the various features and meter operations.

Included with your meter are a 2 stainless steel pin Conduct ivity electrode with built-in temperature sensor (for ATC), a rubber boot, 4 alkaline “AAA” batteries, instruction manual and warranty card. To order other accessories and buffer standard solutions, please refer to the Section on Accessories for more information.

2. GETTING STARTED

2.1 Description of Keypad Functions

The EcoScan CON 5/TDS 5 meter has 6 keys on its splash-proof keypad. These comprise ON/OFF, HOLD/ENTER, CAL, MODE, ∆ and ∇ keys.

ON/OFF: Powers the meter on and turns it off. Meter directly enters measurement mode when you switch it on.

MODE: Selects measurement mode for Conductivity/TDS or Temperature, CAL: Allows calibration mode for Conductivity/TDS and Temperature, or to

abort calibration without confirming any set value.

HOLD: Freezes the measured reading for easy viewing. ENTER: Confirms calibration value. ∆∆∆∆ (UP) / ∇∇∇∇ (DOWN): Scrolls up and down to the values during calibration.

2.2 Description of LCD Annunciators

The meter has a large custom LCD that consists of 3½-digit segments and operation annunciators for uS/mS or ppm/ppt and annunciators include “HO” (when the HOLD function is activated) and “LO” (low battery condition).

2.3 Inserting & Removing the 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.

2.4 Inserting New Batteries

The battery compartment is found at the back of instrument. To open the battery compartment, push in the direction of arrow and lift up the cover. Note the polarity of battery before inserting into position. After replacement, place cover back and press down until it locks tight.

2.5 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.

Caution: Power off the meter when changing battery.

2.6 Connecting the Electrode and Temperature Sensor

To connect electrode into meter, align the connector slots with the posts of meter’s socket and rotate connector clockwise until it locks. Do not force when connecting. To remove, simply rotate the connector in anti-clockwise direct ion until it unlocks, and slide the connector off the socket.
