Test items:
Water quality TDS ppm (mg / L), conductivity us / cm, Celsius temperature ° C, Fahrenheit temperature ° F.
Basic functions:
* Switch / lock button (ON / OFF / HOLD) Function:
Power on: in the shutdown state, press the button, you can boot.
Automatic shutdown: 5 minutes after the use of automatic shutdown.
Manual shutdown: press the button 3s to shut down continuously.
*
Press the function key to display the test water quality conductivity
us / cm value, and then press once to display the Celsius temperature ℃,
then press once again to display the Fahrenheit. The function selection
button (MODE): the default display test water quality total solid
dissolved amount ppm; Temperature ℉; then repeat the cycle to display
the above.
* CLEAR key function: clear. Clear the lock read and re-test.
*
Automatic test and lock reading: clear after the insertion of water can
be automatically read, according to the different water quality shows
the corresponding TDS value or conductivity us / cm value. And then
automatically locked.
* Scale function: according to national
standard scale. And with appropriate reference to international
practice. Direct drinking water warning with reference to national
standards using TDS = 40 for the dividing line. Less than 40 show green
backlight, for qualified straight drinking water, more than 40 show red
backlit, for non-direct drinking water.
* Backlight function:
the use of low-power backlight, easy to night and light dark place for
testing use. At the same time as a direct drinking water to determine
the show.
* Large screen display: the use of high distortion
STN thin liquid crystal, display 4-digit value and the corresponding
physical unit.
