Measuring range conductivity
After the choice of the field
y-range
four fixed measuring ranges can be
selected in the already explained way with the function keys beside the
arrows. If you choose >
auto
<, the HDM99 automatically adjusts the
measuring range, this way an optimal graphic representation of the running
measurement is assured.
By activating the function key
ok
you will get back to the conductivity and
temperature measurement. The vertical axis of the course graphic, as well
as the scale length of the beam display, now correspond to the measuring
range you have chosen.
The temperature coefficient menu point allows many different setting
possibilities. In the parameter menu for conductivity and also conductivity
+ temperature, it is possible to choose from a list of preset temperature
coefficients of various dialysis machine manufacturers. These are listed by
name.There is also a standard value of 2.07% / °C and a user value. The
user value can be changed in the usual way in the adjustment menu for
conductivity. All settings are permanent until the next change. The selected
setting is shown in the measurement menu.
