CONVERSION OF PRESSURE UNITS
13
ە In the DP2 series, the conversion to different units is automatically done on changing the setting of the pressure unit.
However, this conversion can also be obtained by multiplying the values by the coefficients given in the following table.
࣭
For example, if 2kPa is to be expressed in kgf/cm
2
, since 1kPa=1.0197210
-2
kgf/cm
2
, 2kPa becomes 21.0197210
