ture
Via the MODE key different functions can be superimposed, e.g. the function: Pressure
Rate (RATE).
With the 2-channel version of the CPH6400 an additional display of measured tempera-
ture can also be made, using an external Pt100 resistance thermometer. If there is no
Pt100 resistance thermometer connected with this version, then the display shows
"Waiting" instead of the temperature value.
Activation of the Pressure Rate function RATE and optional temperature display
Pressing the MODE key twice* (directly within the standard measuring mode) displays
the pressure rate and the temperature in °C.
Pressing the MODE key three times with an external Pt100 resistance thermometer
(directly within the standard measuring mode) displays the pressure rate and the temper-
ature in °F.
* If you are in a different measuring mode than the standard measuring mode, press the MODE key until the
measuring mode with the Pressure Rate function appears on the display).
