SETTING A CHANNEL DAS240
The recorder DAS240, enable to record the following settings: voltage, current, resistance, temperature (with
a thermocouple, PT100 or PT1000).
We are going to see how to set an acquisition channel, with three examples:
1) Channel 1 configuration with a single voltage
2) Channel 2configuration with a K type thermocouple to measure an ambient temperature
3) Current configuration with a SHUNT resistor
I: Example voltage, setting the channel 1
1- Go to the channels validation by pressing the “Channels and functions On / Off” button:
2- Select the channel. Here we choose channel 1:

3- Go to the channel setting s by pressing on the channel to be set:
4- Set the type of measurement, here we measure the voltage:
5- Choose an adapted caliber for this voltage, in this example: 20V caliber :

6- Set the zero’s position, here we will use the “Min” position because we want to visualize a positive voltage.
The range will be 0 to 20V:
7- It’s possible to use a filter to remove the glitches, here we will choose 10 Hz:

8- Choose the acquisition period, in the example we will use a « 20 ms » sampling period (each channel can
have their own sampling period which is different of the sampling frequency of the recorder):
9- The configuration of the first channel is completed and we can visualized the signal:
