Tips for an Accurate Measurement

• Ensure the sample does not contain any debris.
• Whenever the cuvette is placed into the checker, it must be 

dry outside and free of fingerprints, oil and dirt. 

• Wipe the cuvette thoroughly with 

HI731318

 microfiber 

cleaning cloth or a lint-free cloth prior to insertion.

• Shaking the cuvette can generate bubbles, causing higher 

readings. To obtain accurate measurements, remove such 

bubbles by swirling or by gently tapping the cuvette.

• Do not let the reacted sample stand too long after reagent 

has been added, as accuracy will be affected.

• Discard the sample immediately after the reading has been 

taken or the glass might become permanently stained.

Battery Replacement

To save the battery, the checker shuts down after 10 minutes of non-use and 

2 minutes after reading.

A fresh battery lasts for a minimum of 5000 measurements. When the battery is 

drained, the instrument displays “bAd” then ”bAt”, and turns off. 

To replace the battery, follow the next steps:

1. Press and hold the ON/OFF button to turn the checker off.

2. Turn the instrument upside down and use a screwdriver to unfasten the screw and 

remove the battery cover.

3. Remove the old battery, replace it with a new 1.5V AAA battery, inserting the 

negative end first.

4. Replace the battery cover, fasten and tighten the screw.
