four fixed measuring ranges can be
selected in the already explained way with the function keys beside the
arrows. If you choose >

<, the HDM99 automatically adjusts the
measuring range so that an optimal graphic representation of the running
measurement is assured.
With activation of the function key
ok
you arrive back in the conductivity
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.
