Operating Instructions

EcoTestr EC High Waterproof Pocket Tester

Conditioning Before First Use:

1. Remove the transparent cap and add 20 mm of tap water or calibration standard (approximately ½ full)

2. Recap the EcoTestr and soak* for at least 15 minutes

3. Rinse the cap after use

4. The sensor is now activated and ready for use

Measurement:

1. Remove cap and press to turn on the tester

2. Dip sensor into the test solution

3. Stir once and let the reading stabilize. Note the measured value

4. To hold reading, press . Screen ﬂashes HO once, then displays measurement with blinking unit (mS) to indicate that tester is in the hold mode. Press again to cancel hold mode ( HC)

5. Press to shut the tester oﬀ

Note: Tester automatically shuts oﬀ after 8.5 minutes of non-use to conserve batteries.

Calibration: The EcoTestr is factory calibrated. However, to ensure accuracy, calibration is recommended. Note: Calibration standard sold separately.

1. If the sensor was stored dry, follow “Conditioning Before First Use” steps for best results

2. Press to turn on the tester

3. Dip sensor into calibration standard solution and wait for the value to stabilize

4. Press to begin the calibration. Display shows

CAL

momentarily and blinks the

default reading

5. Press until the blinking value matches the value of your calibration standard at 25 ºC. Note: to set a calibration standard value that is lower than the blinking value, continue to press past the maximum value to continue with the lowest adjustable value

6. Release to accept the calibration value. After a few seconds, (

) is shown and

measurement is resumed

7. To abort calibration, press to escape (

ESC

)

Maintenance: Clean the stainless steel sensors by periodically soaking them in alcohol for 10 - 15 minutes. Rinse sensor with clean water after each use.

Useful Notes: To avoid cross contamination, rinse between samples and calibration standards with clean water.

* The tester cap is not leak-proof. Please keep tester upright during soaking.

Step 1

Slide in left hand thumb to clear the back catch

Figure 1: Removing battery cover to change batteries

Step 2

Slide in right hand thumb to clear the front catch

Changing Batteries:

1. To remove batteries, hold the tester on the left hand with the left thumb slide under the back clip of the cover. This will release the back catch

2. Next, hold the cover with your right hand, at the same time release the front catch with your right thumb. Slide up to remove the battery cover (Figure 1)

3. Replace old batteries with fresh ones. Note polarity as shown in battery compartment

4. No re-calibration is required after battery change. The tester’s non-volatile memory function retains calibration settings

Your EcoTestr includes (4) pre-installed 1.5V alkaline batteries. LR44 or A76 battery types are suitable and commonly available. Replace all (4) batteries together. Waiting too long to replace the batteries can lead to inaccurate readings and is the most common cause of problems.

Error Messages:

– Batteries are weak and need replacement

2. Er – Calibration was attempted with a value that is <5 % of the full-scale range; use a calibration standard with a higher value – Use fresh calibration standard

– Sensor is dirty or has not been soaked

3. Or – Over Range. The measurement is above the range of the instrument (including temperature measurement)

Reset Option: Reset option allows you to restore the calibration back to factory default settings.

1. Press to turn oﬀ tester

2. Press and hold , then press to turn the tester on. The display shows a ﬂashing

(reset)

3. Press again to conﬁrm reset (

) or press to escape (

ESC

) reset option

Warranty: This instrument is supplied with a warranty against manufacturing defects for a period of one year from date of purchase.
