Selecting the temperature coefficient set

To select the current temperature coefficient set press the function key

while in conductivity mode. The

temperature coefficients are shown with their respective temperatures alternating every 3 seconds. The upper
line shows the name of the temperature coefficient set, the middle line shows the temperature and the lower
line shows the temperature coefficient associated with the temperature above. If a single temperature
coefficient is used the values in the lower line are the same.

The

HDM97

Pocket

enables the user easy to choose between vendor specific temperature coefficients as well

as a free adjustable value called "USER TC". Use the

and

navigation key to select between

the machine manufacturers. By pressing the navigation key

the setting will be applied. Pressing the

navigation key discards the setting and the meter returns back to measuring mode.

Which temperature coefficient you should use

First of all please double-check the temperature coefficient with the machine manual.
If you have machines from one manufacturer only in your use the temperature coefficient that the dialysis
machine is using for compensation.

If you have different types of dialysis machines in your unit the best solution is to use a temperature
coefficient of 2.07 %/°C for

all

machines. This avoids confusion with different readings of the conductivity

on different machines.

For your water treatment system use the values according the list above. If the manufacturer is not in this list
use the Non-linear Function (nLF) according ISO7888 – EN27888.

For tap, purified and waste water we recommend to use the Non-linear Function (nLF) according ISO7888 –
EN27888.

Selecting the temperature coefficient

Be  aware  that  changing  the  temperature  coefficient  will  lead  to  changes  in  values
displayed by the meter. Therefore only change the temperature coefficient, if you are fully
aware  of  its  consequences.  If  the  temperature  coefficient  setting  is  wrong  it  will  lead  to
false display values.

The

HDM97

Pocket

is able to apply dynamic temperature coefficients. It supports a set of 2 coefficients for

25°C and 37°C respective. If only one temperature coefficient is needed it is necessary to set both, the
coefficient for 25°C and for 37° to the same value.
