DO Calibration  
Calibration
Turn on the meter or return to the Measurement Mode
 
Select % Mode and Immerse the DO probe in the zero-oxygen solution until READY shows.(Get high accuracy ,please immerse the probe for 3min or longer .
The next steps must be performed only when the expectation value will be below 5%.)
 
Press MODE a few times until the Calibrating is flashing on the Second Display, press HOLD/SET to enter Calibration Mode. (Calibrating stop flashing)
 
The meter will automatically recognize the standard solution and automatic calibration. During this process, calibration value will be shown on the Second Display.
 
After Calibration, meter automatically returns to Measurement Mode.
 
100% Calibration
In the Measurement Mode  
 
Turn on the meter or return to the Measurement Mode
 
Select % Mode and Place the probe at 1cm above the liquid until READY shows.(Get high accuracy ,please keep the probe for 1min or longer .)
 
Press MODE a few times until the Calibrating is flashing on the Second Display, press HOLD/SET to enter Calibration Mode. (Calibrating stop flashing)
 
The meter will automatically recognize the standard solution and automatic calibration. During this process, calibration value will be shown on the Second Display.
After Calibration, meter automatically returns to Measurement Mode.
 
At most 2 points calibration: 0% and 100%, when the solution cannot be recognized, show "Err" for 2s. Then automatically returns to Measurement Mode.
NOTE: For 100% calibration, air calibration way is a simple, quick, approximate method.
(For high accuracy, we recommend that users should regularly calibrate. In the following situation, users must recalibrate meters.)
 
Replace probe
l after measuring aggressive chemicals
 
Restore Factory Default
