BM series 65
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 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 The water temperature currently set (unit:°C, factory setting : 25°C) is displayed.
Use the following keys to change the value.
RE-ZERO (+)key ....The key to increase the temperature by one degree.
(0°C is displayed after 99°C)
MODE (-)key..........The key to decrease the temperature by one degree.
(99°C is displayed after 0°C)
PRINT key............The key to store new water temperature, display end and return to the
density mode. Proceed to Step 1.
CAL key...............The key to cancel the change and return to the density mode.
Proceed to Step 1.

g/cm 3
Entering the density directly
( ldin 1 )
The density currently set (unit : g / cm 3 , factory setting : 1.0000g / cm 3 ) is displayed.
Use the following keys to change the value.
The range to set the density is 0.0000g / cm
3 to 1.9999g / cm 3 .
RE-ZERO 1 (+)key....The key to set the value of the digit selected.
RANGE 1 (-)key........The key to select the digit to change the value.
PRINT key............The key to store the change, display end and return to the density mode.
Proceed to Step 1.
CAL key...............The key to cancel the change and return to the density mode. Proceed to Step 1.
