Low Alarm Value

Option: 

user selectable

The range is influenced by the high-alarm value set (e.g. if high-alarm value is set as 8.00 mS/cm, 
low-alarm value can be set from 0.10 mS/cm and incremented up to 7.90 mS/cm).
“LOW ALARM VALUE” message is scrolled on the bottom of the LCD screen.

   

Note: 

The user can set the low-alarm value with low-alarm option enabled only.

TDS Factor

Option

: TDS factor may be set between 0.45 to 0.99.

Press the arrow keys to change the value.
TDS factor is a conversion factor that is used to change an EC measurement to a ppm measurement.  
Common factors used in the hydroponic industry are 0.5 and 0.7. Consult Nutrient manufactures 
literature to determine the setting for this factor. 0.5 is based upon a sodium chloride solution. 0.7 is 
based upon a Potassium chloride solution.
“TDS FACTOR” message is scrolled on the bottom of the LCD screen.

Note: 

The user can set the TDS factor value with Measurement Mode option set to tdS only.
