Please note, if the alkalinity obtained by the KHG deviate by 1.5 dKH from your desired dKH setting ("KH

auto correction"), KHG will show error messages. KHG will assume this is a major deviation and will

suspend all subsequent dosing of sodium bicarbonate solution and enter into a forced reboot and return

back to standby mode. If the tested value is larger than the "KH auto correction" by +1.5 dKH, KH>ERR will

appear. If the tested value is less than the "KH auto correction" by -1.5 dKH, KH<ERR will appear.

Main Display

Please make sure the RJ45 network cable is securely attached and connect

KHG to your home router or LAN. After switching on KHG, the display panel

will show the IP and port number automatically assigned by the network DHCP

(Figure 7). Please write down the IP and port number shown on the display,

and enter it to the browser of your computer or mobile device to access controls

of the KHG.

If your network DHCP did not automatically assign an IP to KHG, the default IP

will be 192.168.1.10.

For example, if the display were shown as Figure 7, then you should enter

http://172.22.20.158:8090 into your browser. When the login window appears

as Figure 8, enter the password (default setting is "Admin") and Click Login

button, then you will be able to access the controls of KHG as Figure 9.

Get dKH

Press to test and obtain KH value. Counter will be reset after the

testing is completed.

Purge Chamber

Press to purge and empty all solutions in the reactor chamber.

This must be performed every time you intend to move the

KHG. It is crucial to purge reaction chamber to prevent solutions

damaging the optical lens and other electronic components.

Failure to purge chamber could result in KHG failure.

SW Tube De-Gas

Press to pump saltwater sample into the reaction chamber. This

is normally only used at initial setup of KHG, or after reassembly

of the step motor head. By pressing it, saltwater will pump water

up the feeder tube, purging gas from the tube. If there were

blockage in the feeder tube, after a preset amount of time no

water has been pumped into the reaction chamber, the display

would show S.W_ERR error message.
