“ (Filter
= digital filter
).
-
Use button 2 and button 3 to select the desired filter [in sec.].
Selectable values: 0.01 ... 2.00 sec.
Explanation: this digital filter is a digital replica of a low pass filter.
Note: when using the input signal 0-50mV a filter value of at least 0.2 is recommended
-
Press button 1 to validate your value, the display shows “

For configuring the outputs of the EV-94 EB, please follow the instructions given in chapter 4.8.
4.3. Measuring temperature
(Pt100, Pt1000 RTD probes and thermocouple type J, K, N, S or T
)
This chapter describes how to configure the device for temperature measuring with the help of external plati-
num RTD probes or thermocouple probes. This instruction demands that you selected “
t.res
“ or “
t.tc
“ as your
desired input type like it is explained in chapter 4.1. The device has to display “
InP
“.
-
When pressing button 1 the display shows “
SEnS
