Entering the density of a liquid
Two ways to set the density of a liquid are available in the function table, "Liquid density input (ldin): by
entering the water temperature or by entering the density directly.
1 Press the MODE key as necessary to select the density mode.
Press and hold the MODE key (for approx. 2 seconds) to select to "water
temperature" or "liquid density". In the density mode : The unit is "g (gram)". The
processing indicator ( ) blinks. Response adjustment is off.
If you cancel the density mode, press the MODE key.
Entering the water temperature ( ldin 0 )
2 Press and hold the MODE key (for approx. 2 seconds). The water
temperature currently set (unit: °C, factory setting : 25°C) is
displayed. Use the following keys to change the value.
RE-ZERO (+)key
....
To increase the temperature by one degree.
(0°C is displayed after 99°C)
MODE (-)key .......... To decrease the temperature by one degree.
(99°C is displayed after 0°C)
PRINT key............ To store the new water temperature, display
end and return to the density mode. Proceed
to Step 1.
CAL key............... To cancel the change and return to the density mode.
Proceed to Step 1.
