This feature can effectively increase the sensitivity of the electrode and extend the life.–Strategies for adjusting seawater sampling and emissions.–Enhanced Test pretreatment procedure.–S.Raise KH ml/L ability with network submask memory location conflict–For modified three-wheel KRS pump, adjust the calculation method of water droplet shape.–Multiple bug fixes.
V8W.H6A8VD (09/18/2018)–Multiple bug fixes
V8W.H6A8VC (08/15/2018)–AC_ERR–Multiple bug fixes
V8W.H6A8T (06/10/2018)–LCD pH field will display *ERR* when unit experiences an error.–During an error, LCD will display the latest dKH results instead of the last successful dKH measurement prior to the error. –Log Retry: If unit tests a second time due to the first test having unusual results, enter "0" to not record first test to log (Default). Enter "1" to record the results of the first failed test.–> or < 1.5 Alert : If the alkalinity obtained by the KHG deviate by 1.5 dKH from your desired dKH setting (“KH auto correction”). Enter "0" to disable and "1" to enable alarm. –KH Doser Pump : user can set up which baking soda pump to use. 1 is Built-in baking soda pump (not available for "M" model), 1 is Kamoer step pump (available both for "C/M" model).–C.R. suspend time: If the alkalinity obtained by the KHG exceed from your desired dKH setting ("KH auto correction"), After KHG restarts, suspension time (unit:minutes) required for the calcium reactor. Please note that this setting cannot be greater than Check intervals.–Force reverse calibration: In field "REF.KH", enter the value you obtained from a 3rd party test kit and it will calibrate your KHG unit against it.
