Err Range (dKH) :
This is to set the variance range in comparison to the previous dKH value. If the difference of this test
deviates a preset error range from the last known dKH value, the KHG will setup second testing immediately
to verify the result. The unit of value is dKH. We recommend to set it at 0.5 dKH.
Err Try :
This is to set the number of retest to be taken, if the Err Range condition were met.
Last KH (dKH) :
This is only used after a system reset or diagnostics, or if instructed by a qualified KHG support staff.
ADJ KH (dKH) :
This is to force adjustment (correction) of the value obtained by KHG. This is normally used if you believe
there is a constant deviation between the value tested by KHG versus another test kit, and you believe
KHG's value need to be adjusted every time. You can enter the deviation in here. The adjustment value can
be either positive or negative.
Enable KH Auto :
Enter “1” to activate automatic mode. Any other number will cancel the automatic mode. (Feature not
available fo M model.)
KH auto correction :
This is to set your desired tank dKH value. The unit is dKH. As a full functioning dKH controller, KHG not
only monitors your tank alkalinity, but with KH auto correction, KHG will also actively maintain your desired
dKH level. Regardless if you normally maintain your tank alkalinity by kalkwasser, calcium reactor, or
alkalinity dosing, we highly recommend you set your usual alkalinity dosing to a level slightly below your
desired target, and let KHG do the final fine tuning for your tank automatically. (Feature not available fo M
model.)
For example. If your desired tank dKH is 7.5, then please set this number at this field. At the same time,
please setup your normal alkalinity dosing to near 7.0, and let KHG do the rest. KHG will calculate the
difference of the actual tank alkalinity level versus the desired target. Taking account of the total tank
volume, KHG will calculate how much sodium bicarbonate solution to add after each testing.
M.L.Q :
MLQ sets the maximum amount of sodium bicarbonate that KHG can add at any given time. Unit is milliliter
(ml). This is the safety feature for your tank to prevent too much alkalinity to be added into the tank at any
given time. (Feature not available fo M model.)
For example, if this time KHG determines 80 ml should be added into your tank, but you have set the MLQ
at 35 ml, then KHG will only add 35 ml this time into the tank.
